Your Body Was Built for This: The Endocannabinoid System Explained · Bite Me The Show About Edibles

• 0:07
  SPEAKER_00: Welcome to an episode all about the ECS, the endocannabinoid system explained.
• 0:14
  SPEAKER_00: You hear that term thrown around a lot, but what does it really mean?
• 0:18
  SPEAKER_00: Especially in terms of edibles.
• 0:21
  SPEAKER_00: So I'm your host, Margaret, a certified gangier and TCI certified cannabis educator, and I believe your kitchen is the best dispenser you'll ever have.
• 0:30
  SPEAKER_00: And welcome to Bite Me, the show about edibles.
• 0:32
  SPEAKER_00: We can grab a snack and dive in.
• 0:34
  SPEAKER_00: And if you're joining us for the first time, friends, welcome.
• 0:37
  SPEAKER_00: I'm so glad you're here.
• 0:39
  SPEAKER_00: This is an important episode because you hear the ECS talked about frequently.
• 0:44
  SPEAKER_00: And if you've been here for a while, I hope you can learn a little something today.
• 0:49
  SPEAKER_00: Share that you can share with friends and family.
• 0:51
  SPEAKER_00: As we are all advocates for this plant that is cannabis, we are integral to reducing the stigma that exists out there still.
• 0:59
  SPEAKER_00: With that, friends.
• 1:06
  SPEAKER_00: Pull up a chair, pour yourself something cold.
• 1:08
  SPEAKER_00: I already mentioned the snack, and settle in because we're going to do something a little more science-y than is typical, though I've been doing a little more science-related podcast episodes as of late.
• 1:19
  SPEAKER_00: And before you think, oh God, not a biology lesson, I want you to know that this is a topic that I've known about for many years.
• 1:28
  SPEAKER_00: I've read about it in a lot of books.
• 1:29
  SPEAKER_00: I've listened to my own podcast episodes about it.
• 1:32
  SPEAKER_00: What you're about to learn is actually kind of unbelievable.
• 1:36
  SPEAKER_00: Because your body has a whole system inside it that was basically designed to work with cannabis.
• 1:41
  SPEAKER_00: And people, especially who are new to cannabis when they learn about this, are like, wait, what?
• 1:46
  SPEAKER_00: Especially if they have been privy to many, much of the propaganda that we've all been exposed to over the years.
• 1:58
  SPEAKER_00: And I'm not being poetic about it here.
• 2:00
  SPEAKER_00: It's not, I'm not making some kind of metaphor.
• 2:02
  SPEAKER_00: I mean, there literally is a biological system inside every single one of us built from receptor sites to interact with cannabinoids, and it runs your mood, your pain response, your sleep, your appetite, your memory, your immune function, and more.
• 2:15
  SPEAKER_00: And it's called the endocannabinoid system or the ECS.
• 2:21
  SPEAKER_00: And most people outside of cannabis circles have never heard about it.
• 2:26
  SPEAKER_00: I'm sure your doctor didn't tell you about it.
• 2:28
  SPEAKER_00: Your high school health class definitely didn't mention it.
• 2:32
  SPEAKER_00: I don't, I don't remember anything about that in my health class in high school.
• 2:36
  SPEAKER_00: And yet here it is running the show in the background.
• 2:40
  SPEAKER_00: Today I'm going to explain it to you in plain language because you deserve to understand what's happening inside your body when you eat an edible or take a tincture of vaporized flour.
• 2:49
  SPEAKER_00: And I'm going to connect it to something super timely because as we move into summer, at least in this area of the world where I am, you may have noticed that your tolerance does weird things in the heat.
• 3:01
  SPEAKER_00: And there's actually a reason for that, a real physiological reason.
• 3:04
  SPEAKER_00: And we'll get to that because that is something that I have noticed for sure.
• 3:13
  SPEAKER_00: What exactly is the endocannabinoid system?
• 3:16
  SPEAKER_00: So we'll start right at the very beginning.
• 3:17
  SPEAKER_00: The endocannabinoid system, or the ECS, as you'll hear it frequently referred to, was only officially discovered in the 1990s, which by the way means it's younger than some of the people listening to this show, myself included.
• 3:33
  SPEAKER_00: And it is already deeply misunderstood and undervalued, which is kind of relatable.
• 3:39
  SPEAKER_00: The discovery came out of research into THC.
• 3:42
  SPEAKER_00: Scientists were trying to figure out how THC produces effects in the brains.
• 3:46
  SPEAKER_00: And why they what they found was this: there are receptor sites throughout the human body that THC fits into, like a key into a lock.
• 3:55
  SPEAKER_00: These are the receptors.
• 3:57
  SPEAKER_00: And the receptors were there first.
• 3:59
  SPEAKER_00: THC didn't create them.
• 4:01
  SPEAKER_00: The receptors exist because your body produces its own version of cannabis compounds called endocannabinoids.
• 4:08
  SPEAKER_00: Endo means from within.
• 4:10
  SPEAKER_00: So endocannabinoids are cannabinoids that your own body makes.
• 4:16
  SPEAKER_00: Hear that again.
• 4:17
  SPEAKER_00: Your body makes its own cannabinoids on purpose, which is kind of wild because that was definitely left out of the whole like Saint Odo Drugs campaign stuff.
• 4:26
  SPEAKER_00: They they conveniently left out that little scientific detail.
• 4:30
  SPEAKER_00: The two most studied endocannabinoids your body produces are called anandomide and 2AG.
• 4:37
  SPEAKER_00: Anandamide gets talked about a lot because its name comes from the Sanskrit word for bliss, which is like the bliss molecule, which is a very good name for said molecule.
• 4:48
  SPEAKER_00: And 2AG is less poetic but equally important.
• 4:52
  SPEAKER_00: And these compounds get made by our body on demand, used, and then broken down.
• 4:57
  SPEAKER_00: They're not stored.
• 4:59
  SPEAKER_00: They're produced when the system needs them and then dismantled when the job is done.
• 5:05
  SPEAKER_00: So the ECS has three main components: the endocambinoids, I just mentioned, your enandamide and your 2AG, and the receptor sites they bind to, and the enzymes that build and break them down.
• 5:19
  SPEAKER_00: All three parts work together to regulate what scientists call homeostasis, which is just a fancy word for balance.
• 5:28
  SPEAKER_00: The ECS is essentially your body's internal balancing system.
• 5:31
  SPEAKER_00: When something goes sideways, the ECS gets involved to try and correct it.
• 5:36
  SPEAKER_00: And you'll hear this term homeostasis quite a bit when people talk about the ECS or the endocannabinoid system.
• 5:43
  SPEAKER_00: And yes, just a fancy word for creating balance in our bodies.
• 5:51
  SPEAKER_00: So what are the receptors?
• 5:53
  SPEAKER_00: Where do they live and what do they do?
• 5:55
  SPEAKER_00: And that's a great question that gets uh asked often.
• 5:58
  SPEAKER_00: There's two main types of receptors in the ECS.
• 6:02
  SPEAKER_00: There's CB1 and CB2.
• 6:04
  SPEAKER_00: So not that hard to remember.
• 6:05
  SPEAKER_00: And where they're located tells you a lot about what they do.
• 6:08
  SPEAKER_00: CB1 receptors live primarily in the brain and central nervous system.
• 6:14
  SPEAKER_00: They're the receptors most associated with the psychoactive effects of THC.
• 6:18
  SPEAKER_00: When THC binds to CB1 receptors in your brain, that's what produces the high, the altered state of perception, the shifts in time, the munchies giggling, all that stuff that we associate with getting high.
• 6:33
  SPEAKER_00: The CB2 receptors are found mostly in the immune system and peripheral tissues.
• 6:38
  SPEAKER_00: They're less involved in the psychoactivity and more involved in inflammation in your immune response.
• 6:44
  SPEAKER_00: And CBD interacts more with CB2 receptors, which is part of why it's studied so heavily for inflammatory conditions.
• 6:51
  SPEAKER_00: And here's what I told you to hold on to.
• 6:53
  SPEAKER_00: These receptors don't exist because humans decide to smoke plants.
• 6:57
  SPEAKER_00: They exist because your body needs them.
• 7:00
  SPEAKER_00: The ECS uses these receptor sites to regulate your own biological functions.
• 7:05
  SPEAKER_00: Cannabis just happens to produce compounds that interact with the same system.
• 7:09
  SPEAKER_00: That's not a coincidence.
• 7:11
  SPEAKER_00: That is a very interesting piece of evolutionary biology that we still don't totally understand.
• 7:18
  SPEAKER_00: So what does the ECS actually regulate?
• 7:21
  SPEAKER_00: Well, actually a lot, maybe a ridiculous amount of things.
• 7:25
  SPEAKER_00: The ECS has been shown to be involved in pain modulation, meaning how your body processes and responds to pain signals, mood regulation, including anxiety and stress responses, sleep cycles, appetite metabolism, memory formation, immune function, and inflammation, reproductive health, neuroprotection.
• 7:45
  SPEAKER_00: And when I list it out like that, I understand why some people hear it and think, maybe you're overselling it, Margaret.
• 7:50
  SPEAKER_00: Just a bit, just a titch.
• 7:52
  SPEAKER_00: It sounds like someone is about to try and sell you a supplement that cures everything, but that's not what this is.
• 7:57
  SPEAKER_00: The ECS isn't a cure all, it's a regulatory system.
• 8:01
  SPEAKER_00: Think of it less like a medication and more like your thermostat.
• 8:06
  SPEAKER_00: It's always running in the background, making small adjustments to keep things within a functional range.
• 8:11
  SPEAKER_00: It's not dramatic.
• 8:14
  SPEAKER_00: It's just doing its job.
• 8:16
  SPEAKER_00: And the reason cannabis is such a complicated plant from a pharmacological standpoint is that it produces over a hundred different cannabinoids, and many of them interact with this regulatory system in a different way.
• 8:28
  SPEAKER_00: THC mimics anandamide.
• 8:31
  SPEAKER_00: CB CBD doesn't directly bind to CB1 or CB2 receptors the same way THC does, but it influences the system in other ways, including slowing down the enzymes that break down your own endocannabinoids, which means your body's natural bliss molecules stick around longer.
• 8:47
  SPEAKER_00: That's a simplified version, of course, but that's the that's the shape of it.
• 8:57
  SPEAKER_00: So when it comes to tolerance, what actually happens and why?
• 9:01
  SPEAKER_00: So this is where we're going to talk about tolerance because it connects directly to everything we just covered and it connects to what I want to tell you about summer.
• 9:09
  SPEAKER_00: And tolerance is not just getting used to something, it has a specific physiological mechanism.
• 9:15
  SPEAKER_00: When you consume cannabis regularly, particularly THC heavy cannabis, your C B1 receptors respond by downregulating.
• 9:22
  SPEAKER_00: And you've probably heard that term before when it comes to any number of medicines that we can take.
• 9:30
  SPEAKER_00: They actually reduce in number and sensitivity when the CB1 receptor is downregulating.
• 9:36
  SPEAKER_00: So your body is doing exactly what it's supposed to do.
• 9:38
  SPEAKER_00: It detects ongoing stimulation of these receptor sites, and then it tries to recalibrate towards balance by turning down the response.
• 9:46
  SPEAKER_00: The result is you need more to feel the same effect.
• 9:50
  SPEAKER_00: The receptors are still there, they're just quieter and fewer in number until the system gets a chance to reset.
• 9:56
  SPEAKER_00: And this is why tolerance breaks work.
• 9:59
  SPEAKER_00: When you stop consuming THC for a period of time, the receptor downregulation begins to reverse.
• 10:04
  SPEAKER_00: The receptors come back online, the system recalibrates, and then you reintroduce cannabis after a break and you feel the effects much more strongly at a much lower dose.
• 10:14
  SPEAKER_00: And I wrote a guide about this, the fresh start, complete 30-day tolerance guide that you can find on Amazon or as a direct download from my website.
• 10:22
  SPEAKER_00: And it's a 30 days of structure to reset your ECS.
• 10:26
  SPEAKER_00: And it's not about suffering through abstinence, it's about understanding why the break works and what you can expect along the way.
• 10:32
  SPEAKER_00: And I'll link to it in the show notes.
• 10:34
  SPEAKER_00: And what I find interesting about this is last January I ran a communal tolerance break with several people who took a month off of cannabis along with me.
• 10:45
  SPEAKER_00: And it was really interesting to see how people reacted, how they managed what they did in lieu of using cannabis, which is often sort of the go-to.
• 10:54
  SPEAKER_00: And I did find, as did many other people, that after that month-long break, my tolerance did downregulate or did go down.
• 11:05
  SPEAKER_00: I noticed it quite a bit.
• 11:07
  SPEAKER_00: Now I also see now that I've been, you know, back on the cannabis for several months, that it is starting to creep back up again, but it's still not where it was probably before this tolerance break that I took that had been, I hadn't done like a month-long tolerance break in years.
• 11:24
  SPEAKER_00: It was a really interesting experiment.
• 11:27
  SPEAKER_00: I would try it again.
• 11:29
  SPEAKER_00: And there are different, many different ways you can experiment with tolerance breaks.
• 11:33
  SPEAKER_00: It don't necessarily require an entire 30 days, but the guide can walk you through a lot of that stuff.
• 11:39
  SPEAKER_00: But here's the part that most people don't talk enough about.
• 11:43
  SPEAKER_00: The tolerance isn't just about how much cannabis you're consuming, environmental and physiological factors influence the ECS too.
• 11:51
  SPEAKER_00: And this is what brings us finally to summer.
• 11:54
  SPEAKER_00: Summer heat and your endocannabinoid system.
• 11:57
  SPEAKER_00: Here's the part of the episode that I find fascinating.
• 12:04
  SPEAKER_00: Have you ever noticed in the summer that your edibles might hit differently?
• 12:07
  SPEAKER_00: Maybe harder, maybe faster, maybe your usual dose feels like too much, or maybe you've had the opposite experience where you feel foggy and flat, and your edibles seem less effective than usual.
• 12:17
  SPEAKER_00: Heat affects your ECS and it does it through a few different pathways.
• 12:22
  SPEAKER_00: We'll start with the most direct one: heat and receptor sensitivity.
• 12:26
  SPEAKER_00: Your body temperature influences how your CB1 receptors function.
• 12:31
  SPEAKER_00: Cannabinoid receptors are G protein coupled receptors, which is a type of cell receptor that is sensitive to temperature changes.
• 12:39
  SPEAKER_00: When your core body temperature rises even modestly, the binding affinity and activity of CB1 receptors can shift.
• 12:48
  SPEAKER_00: So, in practical terms, this means that cannabis compounds bind more readily or more efficiently at elevated temperatures.
• 12:56
  SPEAKER_00: In some animal studies, elevated body temperature has been associated with increased CB1 receptor activity.
• 13:02
  SPEAKER_00: This is one potential reason why being hot can amplify cannabis experience.
• 13:07
  SPEAKER_00: Your receptors may be more responsive in the heat, which is another interesting thing to mention.
• 13:12
  SPEAKER_00: Animal studies?
• 13:13
  SPEAKER_00: Yes, because all mammals have an ECS system.
• 13:18
  SPEAKER_00: That's pretty wild, right?
• 13:19
  SPEAKER_00: Now, circulation and absorption is also a factor.
• 13:24
  SPEAKER_00: When it's hot outside, your body works to cool itself.
• 13:27
  SPEAKER_00: Blood vessels near your skin surface dilate, blood flow to peripheral tissues increases, heart rate often increases slightly.
• 13:33
  SPEAKER_00: For edibles specifically, increased circulation can affect how quickly cannabis compounds are absorbed from your digestive tract into your bloodstream.
• 13:42
  SPEAKER_00: A more efficient absorption can mean a faster onset and potentially a more pronounced effect, even from a dose you've taken dozens of times before without incident.
• 13:56
  SPEAKER_00: So I'm curious if you've noticed that your tolerance can change or appear to change when it's hot out.
• 14:03
  SPEAKER_00: I'm very curious because I have noticed it myself.
• 14:07
  SPEAKER_00: And what happened is your body changed the conditions, even though the dose didn't.
• 14:11
  SPEAKER_00: There's also something else to consider, which is dehydration in the ECS, which is dehydration is the summer wild card.
• 14:19
  SPEAKER_00: Research suggests that the ECS plays a role in regulating hydration and fluid balance.
• 14:24
  SPEAKER_00: There are CB1 receptors in areas of the brain associated with thirst and fluid regulation.
• 14:28
  SPEAKER_00: When you're dehydrated, the ECS is already activated and working to address the imbalance.
• 14:34
  SPEAKER_00: Layering cannabis on top of an already activated, already stressed system can intensify effects in unpredictable ways.
• 14:41
  SPEAKER_00: Beyond the receptor interaction, dehydration thickens the blood slightly, which affects how cannabinoids move through the system.
• 14:49
  SPEAKER_00: It also affects your liver function.
• 14:50
  SPEAKER_00: And since THC from edibles is processed by the liver before entering general circulation, that's where your 11-hydroxy THC gets produced, the compound responsible for that deep body edibles effect.
• 15:02
  SPEAKER_00: Liver efficiency matters.
• 15:03
  SPEAKER_00: When you're dehydrated, your body is working harder processing changes.
• 15:07
  SPEAKER_00: So the simple version is summer dehydration can make your edibles feel more potent and last longer.
• 15:12
  SPEAKER_00: And it's not a design flaw.
• 15:13
  SPEAKER_00: It's your body responding exactly as it should.
• 15:16
  SPEAKER_00: The mistake is not adjusting your dose to account for it.
• 15:19
  SPEAKER_00: And of course, it does get complicated a little bit because sometimes cannabis can give you cotton mouth, which may also help you stay more hydrated because you're trying to combat that as well.
• 15:35
  SPEAKER_00: Then we have heat and anandemide.
• 15:38
  SPEAKER_00: And this is my favorite part of this whole biological story.
• 15:42
  SPEAKER_00: Exercise produces anandemide.
• 15:45
  SPEAKER_00: Your body makes more of its own bliss molecule, and when you move, especially in sustained aerobic activity.
• 15:51
  SPEAKER_00: For a long time, the runner's high was attributed entirely to endorphins.
• 15:56
  SPEAKER_00: It turns out it's at least partially the ECS.
• 15:59
  SPEAKER_00: Enandemide increases during exercise, and anandamide binds to CB1 receptors.
• 16:04
  SPEAKER_00: In the summer, people tend to be more active outdoors, more walking, more swimming, more casual movement just from living life outside.
• 16:10
  SPEAKER_00: Your baseline anandamide levels may be modestly elevated compared to your more sedentary winter months.
• 16:17
  SPEAKER_00: Add external cannabinoids from your edibles and a system that already has more endocannabinoids running, and you've changed the equation.
• 16:25
  SPEAKER_00: It's a small effect, but in the context of everything we've discussed, small effects stack up.
• 16:30
  SPEAKER_00: So summer heat, elevated circulation, dehydration, increased baseline, anandamide from activity, all that lands on your ECS at the same time.
• 16:39
  SPEAKER_00: As someone who has just come out from a long, cold, dark winter, I can relate to this.
• 16:46
  SPEAKER_00: And I'm sure many of you can as well, because I am definitely spending more time outdoors.
• 16:51
  SPEAKER_00: Whereas in January, well, let's just say I'm definitely a lot more sedentary.
• 17:00
  SPEAKER_00: So what do you actually do with this information?
• 17:03
  SPEAKER_00: You know your body has an endocannabinoid system.
• 17:06
  SPEAKER_00: You know, summer changes how that system behaves.
• 17:09
  SPEAKER_00: So what do you do?
• 17:10
  SPEAKER_00: You just adjust.
• 17:12
  SPEAKER_00: Start lower than you think you need to.
• 17:13
  SPEAKER_00: Stay hydrated, not just because it's summer and you should anyway, but because hydration generally changes how cannabis processes in your body.
• 17:21
  SPEAKER_00: You eat before you dose, not a light snack, an actual meal, because food slows absorption from your digestive tract and gives you a more predictable onset.
• 17:30
  SPEAKER_00: And if you've been taking a standard dose all winter and you're now noticing it's hitting a little bit harder, that's useful data.
• 17:36
  SPEAKER_00: That's your ECS giving you feedback.
• 17:38
  SPEAKER_00: You should listen to it.
• 17:40
  SPEAKER_00: Listen to your body.
• 17:41
  SPEAKER_00: We always hear that all the time, don't we?
• 17:43
  SPEAKER_00: This is where it really matters.
• 17:45
  SPEAKER_00: And if you're someone who's been making edibles at home, this is exactly why precise dosing matters more in the summer.
• 17:50
  SPEAKER_00: You want to know how much THC is in each piece of what you've made, you can adjust it intelligently.
• 17:56
  SPEAKER_00: You can cut your piece in half, add more later if needed.
• 17:59
  SPEAKER_00: You can't do that if you have no idea what you made.
• 18:03
  SPEAKER_00: And this is one of my biggest arguments for learning to make edibles properly at home.
• 18:08
  SPEAKER_00: Your kitchen's the best dispenser you'll ever have, friends.
• 18:10
  SPEAKER_00: And when you control what you make, you can control your high life, even when the seasons are working against you.
• 18:17
  SPEAKER_00: Or is that working for you?
• 18:23
  SPEAKER_00: Why all this matters beyond cannabis?
• 18:25
  SPEAKER_00: The endocannabinoid system is one of the most significant biological systems in your body.
• 18:30
  SPEAKER_00: And most people either have no idea that it exists or don't really think about it very often.
• 18:37
  SPEAKER_00: It's involved in how you process pain, how you sleep, how you feel emotionally, how your immune system fires.
• 18:42
  SPEAKER_00: And for a long time, because cannabis was illegal and stigmatized, research into the system was actively suppressed or underfunded, which is wild when you think about that.
• 18:53
  SPEAKER_00: A whole regulatory system in your body influencing your daily experience of being a human being.
• 19:00
  SPEAKER_00: And we only just started properly studying it in the last 30 to 4 years because it was politically inconvenient to do so before.
• 19:10
  SPEAKER_00: But the good news is the research is accelerating, and every year we understand more about how the ECS works, how to support it, and how things like cannabis, diet, exercise, sleep, and stress all feed into it, the picture is getting clearer.
• 19:23
  SPEAKER_00: For me, as someone who educates about cannabis, this is why I always come back to the science, because when you understand what's actually happening in your body, you can make better decisions.
• 19:34
  SPEAKER_00: You dose more intelligently, you have fewer bad experiences, which is key, and you stop seeing cannabis as something that just works or doesn't work and start seeing it as a sophisticated interaction between the plant and one of your own biological systems.
• 19:47
  SPEAKER_00: And I think that's a much more interesting and empowering place to be.
• 19:51
  SPEAKER_00: Wouldn't you agree, my friends?
• 19:54
  SPEAKER_00: So before I go today, if you want to go deeper on the tolerance piece specifically, I did an episode on tolerance breaks.
• 20:02
  SPEAKER_00: I'll link to those in the show notes.
• 20:04
  SPEAKER_00: The fresh start, complete 30-day tolerance guide walks you through how to structure a break, what to expect, when to reintroduce cannabis.
• 20:12
  SPEAKER_00: I'll link to that in the show notes as well.
• 20:14
  SPEAKER_00: And if you want to understand the science of edibles more broadly, from decarboxylation to dosing to formulation, you can find all of that stuff on the website as well.
• 20:23
  SPEAKER_00: And I'll link to those in the show notes because depending on where you're at and where you want to dig in, there's something there for everyone.
• 20:30
  SPEAKER_00: As always, I appreciate all of you.
• 20:33
  SPEAKER_00: I appreciate you being here and being curious, asking better questions, and taking your cannabis lifestyle seriously enough to learn about how it actually works.
• 20:43
  SPEAKER_00: And with that, my friends, share this episode with somebody that you think needs to learn more about the ECS and what it actually does.
• 20:51
  SPEAKER_00: Until next time, I'm your host, Margaret.
• 20:55
  SPEAKER_00: Stay curious and stay high.
