- 0:23Today, we're talking about toxicology pearls.
- 0:27Joining me here in the podcast studio is Robert Miller.
- 0:31Robert, you have a PharmD. So I'm a pharmacist by education.
- 0:35I've been in the toxicology world for the past eight years.
- 0:40You work for the Long School of Medicine here at UT Health San Antonio.
- 0:45Of course, the larger name here is the University of Texas at San Antonio.
- 0:51You have an important message for clinicians. There's a phone number that's
- 0:56important to call if they have a patient who's in trouble, and there can be
- 1:00a lot of benefits to the doctor calling.
- 1:03So, yeah, I work for the South Texas Poison Center. The phone number is 1-800-222-1222.
- 1:11That is the phone number for the, or really the Poison Center helpline,
- 1:15and this number is very useful to have.
- 1:18And in terms of for clinicians, there's a good reason to call where they can
- 1:23document this for a case and they can let their patient know,
- 1:26I just talked with the poison experts, or can you tell me more about that?
- 1:31We still get a substantial amount of phone calls from parents.
- 1:34However, it's pretty close to 50-50 these days in terms of calls from parents,
- 1:41but then also calls from triage nurses,
- 1:46physicians in the emergency department who have a patient in front of them with
- 1:50a toxic congestion that they're looking for guidance on.
- 1:53And we work at every other level too.
- 1:56Most of our calls will be the emergency department from the clinical perspective,
- 2:01but I also get calls all the time from school nurses, from pediatrician offices.
- 2:07Toxicology, we have a bit of a, when we're teaching and just from a didactic
- 2:11approach, sick or not sick. And that's kind of your first assessment.
- 2:15So if the patient is sick, we can walk you through what this is gonna look like.
- 2:20Length of stay, and obviously the not just supportive care, but the specific
- 2:26types of supportive care.
- 2:29Antidotal therapy, when it's indicated, when it's not indicated.
- 2:32And I can give you, for patients who come in and they're just completely asymptomatic
- 2:36and you're trying to figure out, you know, how long do I need to watch this patient for?
- 2:40We can try and give you some pretty good ballpark disposition information.
- 2:45You can reassure parents and say, look, we talked to the poison control center.
- 2:48Your child's going to be fine. Or I just got off the phone, poison control.
- 2:53This is the plan. Correct. Yeah. And from an emergency medicine perspective,
- 2:58this happens all the time.
- 2:59A lot of parents will just take their kids straight to the emergency room instead of calling us.
- 3:04And then so now it's the hospital staff that are calling us and we're giving guidance.
- 3:09And often, you know, because of EMTELA, I will never say, oh,
- 3:14they don't need to be in the ER. Just just kick them out.
- 3:16That's not how it works. Obviously, if they're in the emergency room,
- 3:19they get to be seen by a provider and evaluated.
- 3:23So we will never say, oh, you can just turn them away. You don't need to see
- 3:27them. They're totally fine. They still get assessed.
- 3:28But we can walk you through the process of trying to get them a very rational kind of disposition.
- 3:34And once again, let's say that the child, maybe they don't need to be in the emergency department.
- 3:38Maybe this is something that the phrase we often use is home observation is
- 3:43appropriate, but the parent is concerned and they need reassurance.
- 3:46You can provide them the case number that we gave you, and they are welcome
- 3:51to when they get back home, if they continue to have any questions or concerns,
- 3:56they can use that same case number.
- 3:57We'll be able to see the chart in the emergency room communication and can kind
- 4:02of provide that sort of continuity of care.
- 4:05And so it's confidential, but not necessarily anonymous. Exactly.
- 4:10Yeah. Confidential, but not anonymous.
- 4:13This really is similar to any other medical charting software.
- 4:17We have the same precautions and the same training in how we're handling protected
- 4:21health information, and we do take it seriously.
- 4:24Robert, you work closely with our emergency clinicians, and I can only imagine
- 4:31what it's like when you're working a
- 4:33A 10-hour shift and you're getting call after call of people who are panicked,
- 4:38probably. How do you do that?
- 4:41What is your strategy? I'm not rushing things along. There's no metrics.
- 4:46I am going to handle the call start to finish. I will say that I think we are
- 4:52very similar to pediatrics in that sense, and that a large part of our job is
- 4:56reassurance, and it is taking care of, you know, the child is our patient,
- 5:00but just as much to some degree, so is the parent.
- 5:03And we are once again trying to offer them up reassurance.
- 5:07There's a lot of strategies and things I've learned over the years as to how I approach that.
- 5:12I think some things parents appreciate hearing is that this is,
- 5:17you know, to them, this is a very unique situation.
- 5:20Most parents will comment that they, you know, oh, this is my first time calling,
- 5:24or I've only had to call once before for my other kid.
- 5:27But for us, you know, we typically end a shift with anywhere between 30 and
- 5:3140 calls. And so this is just business as usual.
- 5:34So often I will try and reassure parents by explaining, oh, no,
- 5:39this happens all the time.
- 5:41You know, kid gets into a Zyrtec. Kids get into Zyrtec all the time. Kid got into melatonin.
- 5:46Well, ever since they made it a gummy, kids love to get into it.
- 5:49Oh, my kid got into my medicine cabinet and he ate the whole bottle of Tums.
- 5:53Well, no, that's not your fault ever since they made it into a smooth berry
- 5:57flavor instead of tasting like chalk.
- 6:00Yeah, if kids get into one, they never get into one. They get into 30.
- 6:04And our listeners know very well, we're going through an epidemic right now
- 6:09of depression, anxiety, and adolescent self-harm. So.
- 6:18Let's start off with that, with these toxicology pearls.
- 6:22What is your advice there when it comes to things that kids could easily find
- 6:29around the house, such as Tylenol, Advil?
- 6:33Exactly. So I think that really sets the stage for, we're kind of very unique in that regard.
- 6:38You know, most people will see, or excuse me, most physicians will get into
- 6:46a specialty and they will see just a very wide range of demographics.
- 6:51Obviously, in pediatricians, the demographic is the specialty.
- 6:55And we're kind of like that, too. So there's kind of a there's an interesting
- 6:58sort of U-shaped curve where a very substantial amount of our call volume are
- 7:04what we call pediatric exploratory ingestion.
- 7:07So these are your children that are age zero through six that are crawling around,
- 7:12getting into stuff. And the median age is overwhelmingly two.
- 7:15The moment they start moving around, they are going to find things.
- 7:19And, you know, kids explore the world with their mouth.
- 7:22So if they find something, they will get into it. So it might sound a little
- 7:27bit trite, but probably the number one advice for this age range is just basic
- 7:33practices of keeping stuff up high, keeping stuff locked up.
- 7:37Be cautious about storing chemicals and things of that nature under the cabinet.
- 7:41Be cognizant of the fact that when your relatives visit, they might bring pill minders.
- 7:46So even if you're very careful, you know, they may not be. Especially grandparents.
- 7:52Grandparents in particular. And partly the issue is that for thinking about
- 7:57like a geriatric population, what medications are they on?
- 8:00They're frequently on anti-diabetic medications, blood pressure medicines, painkillers.
- 8:06And these are unfortunately a
- 8:07lot of the medications that do often send children to the emergency room.
- 8:11In contrast, if a child gets into a cholesterol drug, that usually we can keep
- 8:18something like that at home.
- 8:20When I have three kids, when they were younger, we had this rule that I would stress with them.
- 8:26If they find something that looks like a candy, piece of candy on the floor
- 8:30to come show it to me or wherever they find it, the couch or whatever.
- 8:34And if it is a candy that they could eat, they could eat it.
- 8:39But if no matter what, if it's a medication, then I will give them a piece of candy.
- 8:44And even just at a very young age, that did happen where there was a grandparent
- 8:50visiting and red pill had fallen out of the grandpa's pocket.
- 8:55And when one of the kids came up and showed it to me and I was so glad.
- 9:00So I don't know, does that sound like an OK strategy or?
- 9:04Well, you definitely hit on this is a fundamental just double edged sword with pediatrics.
- 9:09How do you convince kids to take medicine?
- 9:13And, you know, we take steps both both at the personal level as parents,
- 9:17but also on sort of a commercial level, you know, kind of going back to what
- 9:22I previously mentioned, you know, we make these things taste good.
- 9:25We make them look like candy to sort of coax kids into being more amenable to taking them.
- 9:31But that comes with the consequence that at that age, they cannot tell the difference
- 9:35between candy and pills.
- 9:36And so that can sort of complicate the issue.
- 9:39So what we typically recommend is, yeah, there's some specific context in which you have to use it.
- 9:46So it doesn't fit every single permutation of a toxic ingestion.
- 9:52But for most people with an acute acetaminophen ingestion within the past 24
- 9:57hours that present to the emergency room, we can do a pretty good job of assessing
- 10:01if they need or do not need the antidote.
- 10:05So the antidote is in acetylcysteine.
- 10:09If the child is having anxiety, depression, there's a risk of self-harm.
- 10:14Keep all medications locked up.
- 10:17Another thing that you encounter is something that happens because so many medications,
- 10:24as we know today, have so many different ingredients in them.
- 10:29Yeah, I will say that kind of gets to another core problem, kind of talking
- 10:33about acetaminophen in general. This is a very common situation I'll get.
- 10:36The parents bring their child into the emergency room and say,
- 10:39oh, they overdosed on ibuprofen.
- 10:41So we might be having a conversation with the physician on, oh,
- 10:45here's what to expect with that.
- 10:48Generally, I don't want to say well-tolerated, but let's just say it takes a
- 10:52substantially greater amount of ibuprofen to cause true toxicity relative to acetaminophen.
- 10:58And so I'll walk them through the process of getting the labs and watching them
- 11:01for a couple hours. And then the labs come back and they have a positive Tylenol level.
- 11:06And so, well, what's that happening? And then we go back and talk to the parent
- 11:10and we say, wait, so did they overdose on ibuprofen or did they overdose on Tylenol?
- 11:15And we'll get that, well, aren't they the same thing? And it's one of those
- 11:18things you kind of take for granted is when you're a healthcare worker,
- 11:21you recognize that aspirin and ibuprofen, naproxen and acetaminophen,
- 11:27these are all three distinct drugs.
- 11:30But for parents often it's just, well, that's the over-the-counter painkiller
- 11:33we have at home. They're all the same.
- 11:35So that happens a lot. One thing I'll also mention is there's this phenomena
- 11:39called the acetaminophen occult ingestion.
- 11:43And here's how this generally plays out is where the child is trying to hurt
- 11:49themselves, so they overdose on the Tylenol at home. It doesn't do anything.
- 11:54So they conclude that, oh, it didn't work. So now they overdose on,
- 11:59let's say, their prescription medicine. So just to grab an example,
- 12:02let's say it's their eschatolopram, so Lexapro.
- 12:08So the parents recognize that that's a problem.
- 12:11So they take them to the emergency room and, you know, we're working them up
- 12:15for the Lexapro overdose and we get that Tylenol level or we see their,
- 12:19or more realistically, if it's been greater than 24 hours, you might have a
- 12:22situation where the Tylenol level is undetectable.
- 12:25But now their liver enzymes are rising and we're trying to figure out what's going on.
- 12:30And then they finally disclose that they actually had overdosed on acetaminophen earlier.
- 12:34So we actually have pretty good data on this about somewhere in the ballpark
- 12:39of 3% to 5% of patients who present to the emergency room with a chief complaint
- 12:45of a toxic ingestion that is not acetaminophen will ultimately end up having
- 12:50a positive acetaminophen level.
- 12:52So if you're curious, this is why we are so adamant that if a psychiatric patient
- 12:58shows up to the emergency department with a toxic ingestion,
- 13:01we're going to recommend a Tylenol level just because it's easy to check and
- 13:05it can spare a ton of misery over the next 72 hours as opposed to if we miss it.
- 13:14And there are a lot of marijuana products out there that look like candy and
- 13:19probably taste really good.
- 13:21Let's talk about THC. Let's talk about THC. So THC is a very interesting substance.
- 13:28Obviously, it's been around pretty much forever.
- 13:30But over the past 10 to 15 years, it really has just exploded in popularity.
- 13:38And a particular inflection point happened in 2018. This was when the federal farm bill passed.
- 13:46So this is kind of a piece of omnibus legislation. It's just one of those things
- 13:50that every Congress has to pass to, you know, mostly what it's doing is keeping
- 13:55like farm subsidies going.
- 13:56However, in this particular 2018 version of the bill,
- 14:01it had an exception in which products that had less than 0.3% of THC and were
- 14:10hemp-derived were kind of legally allowed federally.
- 14:13And so it's an interesting kind of gray zone where technically marijuana is
- 14:19still schedule one, but this particular product,
- 14:23let me rephrase that, these products that were derived from that hemp at that
- 14:28certain percentage were legally allowed.
- 14:31This was really the catalyst that caused this explosion of why there's a vape
- 14:36shop on every corner, basically.
- 14:38I'm sure anyone who's driving around Texas has observed this phenomena.
- 14:42The problem is that these products, they're generally intended for what we would
- 14:48call like the experienced marijuana user.
- 14:50You know, these are people who know what dose gets them their desired effect.
- 14:55And most people would traditionally be smoking marijuana, which kind of is self-titrating, right?
- 15:01They smoke to a desired effect and then they stop smoking.
- 15:03However, for most users that do not want to smoke, they have turned to edibles.
- 15:10And edibles present a pretty unique risk profile for children for multiple reasons.
- 15:15You know, one is kind of what we already talked about. These products are intended,
- 15:19and this is not an accident, like they look like candy.
- 15:23And more concerning is that they're explicitly marketed as candy in some context.
- 15:28They may obviously have warning signs and symbols all over them.
- 15:32What does that mean if you're a two-year-old, of course, right?
- 15:35So parents may be able to read that and understand some precautions.
- 15:39But if kids find them and they look like candy, they will eat them.
- 15:43The main problem with edibles, of course, is that there's two issues.
- 15:48One is kind of a pharmacokinetic issue, right?
- 15:51Once again, you smoke, you get a desired effect, you stop. With edibles,
- 15:54you may not see the inebriation for two or three hours.
- 15:57And so this applies to both adults that are trying it for the first time,
- 16:01but also for our kids that are just accidentally getting into it.
- 16:04They may eat one, they may eat two, they may eat ten. Thank you.
- 16:10And eventually, they're going to get that entire dose. It may be in a delayed
- 16:14fashion, but it may be a substantially greater dose than what they can tolerate.
- 16:19Obviously, in a two-year-old, any dose is going to be intolerable.
- 16:23But even, quote-unquote, experienced users may be taken for a surprise.
- 16:29And so this is why you're seeing this kind of substantial explosion of this
- 16:33sort of alphabet soup of THC products.
- 16:35Most people are familiar with THC, but unless you work in toxicology and you
- 16:40see these ingestions or you're a user, then you may not recognize Delta-8,
- 16:45Delta-9, Delta-10, THCA, THCP, et cetera, et cetera.
- 16:49And while there are some potency differences, and I don't want to say there's
- 16:53absolutely no qualitative difference between them, that that's not entirely correct,
- 16:58at the end of the day, from a pediatric perspective, all of them can be potentially
- 17:02inebriating for a child.
- 17:05And marijuana products, marijuana itself is much stronger today.
- 17:11Yeah, that's correct. You know, generally the people who were making marijuana,
- 17:18but, you know, growing the plants, cultivating it, selling it,
- 17:21the stuff that would kind of come in from overseas, it was relatively weak in a modern sense.
- 17:26You know, your kind of person who's at Woodstock and smoking a blunt,
- 17:32that may have been like 5% THC back in the day. These days, this really is like
- 17:36an enthusiast industry.
- 17:38These people are obsessed with getting these concentrations as high as possible.
- 17:45They're looking for a certain experience. And so these products,
- 17:50not only is this concerning for just the pediatric exposure,
- 17:53but I even run into this with adults too.
- 17:56A 50-year-old who has never tried marijuana before, or maybe they tried it as
- 18:00a teenager, might go to the gas station and see one of these products. Yeah.
- 18:05So they may find one of these products and try it for the first time.
- 18:08And, you know, spoiler alert, a 30 milligram dose is not a really smart idea
- 18:12for someone who is completely naive to these products.
- 18:15So even adults can be really surprised at the magnitude of inebriation they
- 18:20can end up experiencing.
- 18:21And it can't be good for the brain. Yeah, that's another concern,
- 18:25too, is there's obviously a very large debate about this,
- 18:29and I won't pretend that it is necessarily settled science, but epidemiologically,
- 18:34it's becoming pretty clear that these adolescents who,
- 18:39the earlier they start smoking, and obviously there's a cumulative dose effect,
- 18:44that it does seem to be linked to psychosis, psychosis,
- 18:47especially if there's any kind of either direct history or family history of
- 18:52psychiatric illness, it does seem to just substantially increase their risk
- 18:57that as they move on to young adulthood and as an adult,
- 19:00there'll be higher risk for things like schizophrenia,
- 19:03anxiety, depression, etc.
- 19:06And so many medications and come in gummies, gummy form now.
- 19:11I remember even like prenatal vitamins in gummy form. Like if my toddler at
- 19:17the time got into that, that could be disastrous.
- 19:19But when it comes to a THC gummy, I just can't even imagine.
- 19:23What do you do if a child ingests a gummy or gummies?
- 19:29Exactly. And this is what kind of gets to the heart of the matter.
- 19:31Someone might kind of naively, because in adults, it really isn't a big deal. most of the time.
- 19:37And I'm trying, I don't intend to be tried or anything like that.
- 19:41But as long as there's no fall risk or risk of secondary accident,
- 19:46most adults are not going to seize or have airway issues or a cardiac dysrhythmia.
- 19:52It's just not going to happen at any reasonable dose in an adult as far as we can tell.
- 19:56But this kind of gets into a classic problem of just, you know,
- 19:59children are not small adults.
- 20:01Their CB1 receptors are fundamentally different and they do seem more sensitive to it.
- 20:06So, you know, don't get me wrong, your kid who gets into a single edible most
- 20:11likely will be okay with just clinical observation. They probably won't need
- 20:15substantial interventions or anything of that nature.
- 20:18However, these kids who, you know, get the 400 milligram thing that looks like
- 20:24a nerd rope and down the whole thing, we actually do see children who have airway
- 20:29issues, dysrhythmias, seizures.
- 20:32So they are just categorically different. And once again, And because these
- 20:36are edible products, they can have substantially longer half-lives than the
- 20:41pyrolyzed marijuana products.
- 20:44And so these children may have a length of stay of sometimes as long as three days.
- 20:49And then is there anything you want to say about the process of helping the child to survive?
- 20:55But we very rarely will go to stomach pumping just because by the time the child's
- 21:00presenting to the ER, most likely that that risk is passed.
- 21:04And, you know, with a child who's coming in and already kind of attended and at risk for a seizure,
- 21:10we would be really concerned about being really aggressive with gastric lavage
- 21:15just because unless the airway is protected, you really are introducing an aspiration risk.
- 21:20So the care is symptomatic and supportive at the end of the day.
- 21:23I will say from a disposition perspective, what we've kind of observed is generally,
- 21:29assuming the child is ambulatory to begin with, ambulatory status is kind of
- 21:34the first thing to go and the last thing to come back.
- 21:37So that can be kind of valuable to a clinician who's assessing,
- 21:40you know, is this child sick and when is this child ready to go home?
- 21:45Anything else, Robert, you want to say about THC and the products out there
- 21:50for the pediatrician or the parent?
- 21:53So it was kind of interesting. There was a toxicology conference where we actually
- 21:58did have one of the, and I apologize, I don't remember his name,
- 22:02but one of the big wigs of kind of the,
- 22:04let's call it the Colorado cannabis industry came and kind of talked to us.
- 22:09It was interesting to see because people were really just kind of grilling this
- 22:12guy with questions, but he made a comment that, look,
- 22:17you know, if you are using these products at home, you absolutely should have
- 22:23a lockbox, and they should be in that lockbox, no exceptions.
- 22:27And, you know, you can definitely kind of push back and say that,
- 22:32no, you know, you as an industry have some responsibility for this,
- 22:35and you really should be changing the packaging.
- 22:38I think you kind of have to accept the reality that unless there's legislation
- 22:41forcing them to do this, they're probably not going to voluntarily do anything
- 22:46to kind of stop this situation.
- 22:47So while I kind of understand why people were very critical of him.
- 22:51Ultimately, he's not wrong. I actually do agree with that. If you are using
- 22:55these products, you absolutely need to have a lockbox.
- 22:59Okay. And that's great advice. And then I know we're going to talk in a minute
- 23:04about Zen pouches, which I didn't even know what that was until over spring
- 23:08break when my son told me a relative we were with was taking them on the ski slopes.
- 23:16Zen pouches, so that's, it has a delayed response.
- 23:21Can you tell us about this? Yeah, so Zen pouches are becoming very popular,
- 23:26and they also have kind of introduced a unique concern for pediatrics.
- 23:31So most of your typical nicotine products, well, one, you have to kind of differentiate,
- 23:36you know, is this a tobacco product or is this a straight nicotine product.
- 23:41And in both of these situations, traditionally, they've kind of been self-limiting.
- 23:46Like, it doesn't take that much nicotine for a child to develop nicotine toxicity.
- 23:51What are Zen pouches? Is it nicotine?
- 23:54So there's no tobacco in a Zen pouch. It's nicotine only? Yeah, exactly.
- 24:00Correct, yeah. So your typical nicotine products are kind of divided into the
- 24:04kind of what we would call straight nicotine products.
- 24:06So these are things like a lot of smoking cessation aids, right?
- 24:10So you go and buy the nicotine gum, the nicotine lozenge, and then you have
- 24:15all your tobacco products, of course.
- 24:17Snuff, dip, cigarettes, of course.
- 24:20The other major nicotine player these days, of course, are the vaping products.
- 24:24Both the kind of refillable ones with nicotine solution, but also what's kind
- 24:30of becoming the predominant one there are the disposable vapes you can buy at
- 24:34the gas stations and things of that nature.
- 24:37What makes Zinn unique is that this is a pouch that you kind of insert into
- 24:41your mouth and kind of just keep there either under the tongue or kind of bucally
- 24:46in general, and it will absorb the nicotine.
- 24:49And these are unique because this is not a tobacco product. This is straight nicotine.
- 24:55And so this has kind of introduced a risk for children for a very specific reason,
- 24:59and that has to do with the kind of delayed absorption aspect of it.
- 25:03So kids frequently get into nicotine, and while it's very dangerous,
- 25:07you know, it only takes about 20 milligrams, and children really can have like
- 25:10full-blown nicotine toxicity,
- 25:14with fasciculations and airway problems because their accessory muscles are getting weak.
- 25:20Yeah. So essentially what I'm concerned about is, you know, children having tremors.
- 25:24Nicotine is kind of what we would call biphasic in the sense that it starts
- 25:28kind of stimulatory, but then their muscles essentially just fire to a point
- 25:32where they get very rapidly fatigued after that sort of stimulant period.
- 25:37And that's when they start turning in. So what I would generally tell a parent
- 25:41is what I'm mostly concerned about sort of a floppy baby kind of situation, this hypotonia.
- 25:49So how much, again, can you stress like in a Zen pouch if a child ingests can be dangerous?
- 25:57Yeah. So what makes Zen, yeah, basically any amount.
- 26:02And the reason for that is you might look at the Zen pouch and not think much
- 26:06of it because it's quote unquote only three to six milligrams of nicotine.
- 26:10Whereas in contrast, a cigarette can have quite a bit more than that.
- 26:14But you start getting into finer details of pharmacokinetics.
- 26:18So if a child ingests a cigarette, it's kind of gross.
- 26:22But at the same time, like when you think about how much nicotine in that tobacco
- 26:26is bioavailable, kids ultimately only end up getting a couple of milligrams.
- 26:30And usually it'll be what we consider sort of self-limited.
- 26:35So the child will pretty much guarantee to get some an emetic effect from it.
- 26:40And they'll generally kind of puke it up before it's a problem.
- 26:42So one of those exposures that in theory is very serious, but it's actually
- 26:47pretty infrequent that we have to send them into the emergency room.
- 26:50The Zen pouch becomes really problematic because it's sort of bypassing that issue, right?
- 26:57So because it's nicotine in this pouch and the child swallows it,
- 27:02what they've done is they've essentially swallowed an extended release nicotine product.
- 27:07So it's going to get past the stomach, it's going to go into their bowels,
- 27:11and there it's going to absorb.
- 27:14So yes, it's quote-unquote only three to six milligrams, but the child is often
- 27:18getting the full burden of that nicotine dose, whereas more pragmatically in
- 27:23other contexts, they might have a much more limited exposure.
- 27:26And the emetic effect might not be as pronounced, so their ability to quote-unquote
- 27:31self-decontaminate is limited as well.
- 27:34And the parents may not even, what I've had very frequently happening is the
- 27:38kids like digging into the trash or finding these used Zen pouches, excuse me.
- 27:44And what's concerning is you might think, well, they're used up,
- 27:48but you're not absorbing every bit of the nicotine.
- 27:52So even the used pouches still have some nicotine content.
- 27:56What's the appeal with the Zen pouches? I think, so I'm not personally a user,
- 28:01so I won't try and give like a subjective answer.
- 28:04Yes, I would have been very worried if you said you were Zen pouches.
- 28:07My understanding is just that, well, one, they're frequently flavored.
- 28:12So people tend to like that.
- 28:14And I think also just like, once again, they are straight nicotine.
- 28:19So if you think of all the, a lot of the cancer risk and things like that stem
- 28:24primarily from the tobacco product.
- 28:26So let's say like if you're using snuff, you know, there is a risk of oral cancer
- 28:30that's pretty uncontroversial.
- 28:33Not to say that we don't have a ton of evidence that these Zen pouches are safe
- 28:36necessarily, but they're not tobacco. So a lot of your more traditional risk
- 28:41factors in theory may be lower. So I think that's part of the popularity.
- 28:46I also think it's a little bit of like a Kardashian effect. like they're popular
- 28:49because they are popular.
- 28:51But nicotine can't be good for us, right?
- 28:55Yeah. I mean, often people will say, well, nicotine itself is harmless,
- 28:59but go ask any vascular surgeon and they will disagree with you.
- 29:04That said, you know, it's kind of a risk like we talked a lot about marijuana
- 29:08and, you know, that obviously always triggers a very large debate of marijuana versus alcohol.
- 29:14And it's kind of like at the end of the day, yeah, some of this societal burden
- 29:20of these substances are pretty gargantuan.
- 29:23But when you get into the specifics of like which one is worse and which one
- 29:26is better, you know, it's all going to be very context dependent.
- 29:30And again, it's something that's flavored, so it could be really attractive
- 29:34to a child who finds it. Exactly.
- 29:36And dangerous. Kratom. Kratom. What is kratom and what's the concern there?
- 29:42So kratom is kind of an interesting substance. This is a plant that's had a
- 29:47very interesting history in the past 20 years.
- 29:50So this is a plant from Southeast Asia.
- 29:53And originally, so it's a very interesting pharmacologically,
- 29:58this is an atypical opioid, which you just don't run into that much.
- 30:03There's a few synthetic ones like tramadol, but as far as naturally occurring
- 30:07ones, there really aren't too many.
- 30:09So this is kind of a unique drug in that context. And Kratom has had very much
- 30:13a transition period where originally Kratom was being used primarily by adults
- 30:19who were suffering from opioid addiction.
- 30:22And this was essentially their way of trying to do medication-assisted therapy
- 30:27or what we would call MOUD these days.
- 30:31You know, trying to stave off that Kratom withdrawal while they try and get
- 30:35off their fentanyl or their prescription opioids.
- 30:39That has kind of transitioned into several interesting phenomena.
- 30:43One is that, yes, I don't want to say it's effective because we don't have any
- 30:50RCTs, obviously, randomized controlled trials.
- 30:54So no one is really doing any kind of evidence-based assessment of this as an
- 30:59opioid alternative. Mm-hmm.
- 31:02That being said, you know, just talking to patients and looking at kind of forums
- 31:07where people discuss using Kratom, it's very clear that Kratom itself has some addictive properties.
- 31:13And so, you know, kind of the traditional accusation against MAT or medication-assisted
- 31:19therapy, excuse me, is, well, isn't the patient just replacing one addiction with the other?
- 31:23And that kind of happens with Kratom too.
- 31:26You know, this is not really physician-supervised in most contexts,
- 31:29and so that's kind of been a problem. But what's really happened is Kratom has
- 31:34kind of also emerged in this sort of gray, you know, legal but not legal kind of drug scene.
- 31:40And so it's kind of transitioned to if you were an opioid user and you learned
- 31:45about Kratom, it was a very kind of under the table thing. You learned about it.
- 31:49You knew to ask for it. It was kind of a behind the counter thing.
- 31:52And that's really changed in the very recent history where now like everyone's
- 31:57familiar with this and it's kind of becoming more just like a general recreational
- 32:01drug and that's concerning for multiple reasons.
- 32:05One is it is an opioid but it's an atypical opioid and as far as we can tell
- 32:10it's a bit controversial if this drug causes seizures or if it's kind of simply
- 32:15lowering the seizure threshold and so other risk factors are necessary for that to manifest.
- 32:20But regardless, you do have patients showing up to the emergency room with seizures.
- 32:24Obviously, the reason I'm bringing this up is, you know, from a pediatric toxicology
- 32:29perspective, we now have the phenomenon of parents have this product in their
- 32:33home and their kids are getting into it because they can't tell the difference.
- 32:38Of course, once again, they typically don't look explicitly like candy,
- 32:42but they are in sort of an edible.
- 32:45They often don't look like pills either. So that can be a problem as far as pediatric exposure.
- 32:51And when they come in, they actually, they can have seizures and we also,
- 32:55you know, it can also function like a more classic opioid in kind of children.
- 32:59And so we do see some respiratory depression as well.
- 33:02There's also been a very increasing incidence of adolescents that are using it.
- 33:07You know, this is sort of a, this is very popular right now on social media
- 33:11and Instagram. So, same basic principle.
- 33:14If you have a teenager, they may be very tempted to kind of start this stuff.
- 33:19And once again, you know, there's really no doubt here that there are addictive qualities to it.
- 33:24And so, you know, if you have a child who's using it, it is something to seek medical advice about.
- 33:30And can you tell us about the harm it could be causing you?
- 33:34So as far as longitudinal risk, I think that is still to be determined at this time.
- 33:39Acutely, it does go back to just that very basic pharmacology,
- 33:43just atypical opioid with a risk of seizures and with a risk of airway depression
- 33:49if they use too much of it.
- 33:50Well, Robert, this is all so insightful. I really appreciate you being here
- 33:55in the podcast studio and talking about what you see on a day in, day out basis.
- 34:02Right now, the 1-800 number for the Poison Center, it might be moved to a three
- 34:10number like 911, but that hasn't happened yet.
- 34:13Exactly. So as of right now, the phone number is 1-800-222-1222.
- 34:19We would love to transition to a sort of three-digit number,
- 34:22so to speak, but there's some logistical issues, and you do have to have some
- 34:27legislative involvement for that to happen. And so it's something we're working on.
- 34:30But unfortunately, I don't have a time frame at the moment.
- 34:35And Robert, I know you said that you're working on studying for your board exams.
- 34:40So there's not a lot of things you're doing outside of the world of medicine.
- 34:43But you have a favorite quote.
- 34:45So my favorite quote is by H.L. Mencken.
- 34:48And this is me paraphrasing it. Originally, it has a slightly different connotation.
- 34:54But essentially, it's this idea that, you know, for every complex problem in
- 34:58the world, there's always a solution that's simple, elegant, and wrong.
- 35:04And I think that a lot about, that quote comes to mind a lot when we talk about medicine.
- 35:10Robert Miller with the Department of Emergency Medicine and the South Texas
- 35:15Poison Center in UT Health San Antonio.
- 35:17Thank you so much for being here today on Pediatrics Now. Been really insightful.
- 35:23Yeah, thank you so much. Pediatrics Now is brought to you by the Department
- 35:26of Pediatrics at UT Health San Antonio and University Health's new Women's and Children's Hospital.
- 35:34Don't forget to click on the link in this podcast for free credit.
- 35:39I'm Holly Wayment. I'll see you next week. And so one thing I really want to
- 35:44stress is, you know, when you call a poison sinner, you talk to a human being.
- 35:48You know, there's no robots. There's no artificial intelligence.
- 35:51There's no complicated phone tree standing between you and answer.
- 35:56You really just talk to another person.
