You’re sitting on the couch, mid-snack, and suddenly you wonder: What if dogs think we’re the pets? Or maybe you’re deep in a conversation about the meaning of time, convinced you’ve cracked the code to the universe—only to forget it five minutes later.
If that sounds familiar, you’ve probably experienced what many people call a “high thought.”
Whether it’s a mind-blowing epiphany, a random (but somehow genius) idea, or a looping train of thought that goes nowhere fast, cannabis has a reputation for sparking all kinds of unusual mental detours. And while it might feel like your brain is off on its own little adventure, there’s actually some neuroscience behind these changes in thinking.
So why does cannabis make your thoughts feel deeper, funnier, or more intense? What’s really going on in your brain when you're high? Keep reading to explore what “high thoughts” are, how cannabis affects the way you think, and why that experience can sometimes be creative, insightful—or downright weird.
What Are High Thoughts?
You know those moments when, after you consume cannabis, you suddenly feel like you’ve unlocked the mysteries of the universe—or at least come up with the perfect name for a sandwich shop? That’s a high thought.
They can be deep, random, funny, or straight-up bizarre. One minute, you’re wondering if plants can hear your thoughts; the next, you’re rethinking your entire fifth-grade science project. These mental detours are a common part of the cannabis experience, and while they might feel totally out of left field, there’s actually something going on behind the scenes in your brain.
High thoughts aren’t about thinking “wrong” or even necessarily “differently”—they’re more about noticing patterns you usually ignore or tuning into ideas you’d normally brush off. Sometimes, they lead to creative insights or introspective moments. Other times, it’s just your brain chasing a wild idea because, well, it feels kind of interesting.
It’s your brain reacting to cannabinoids in ways that shift how you process information, emotions, and memories. And the science behind that is actually pretty fascinating.
How Cannabis Affects the Brain
So, what’s actually going on in your head when a high thought hits? To get it, we’ve got to talk brain chemistry—but don’t worry, we’re keeping it simple and way less boring than high school bio.
Your brain has its own built-in system called the endocannabinoid system (ECS). Think of it like your body’s internal messaging network—it helps regulate everything from mood and appetite to memory and perception. And when you consume cannabis, especially THC, it interacts with that system in some pretty interesting ways.
THC fits into your brain’s CB1 receptors—these little guys are found in areas that control things like memory (hello, hippocampus), decision-making (what’s up, prefrontal cortex), and emotion (shoutout to the amygdala). When THC binds to those receptors, it can throw your usual thought patterns into a remix, kind of like a DJ flipping the track you’re used to hearing.
According to a 2019 study in Nature Communications, cannabis use can disrupt typical connectivity between brain regions that are normally synchronized. That might sound technical, but what it means is this: your brain starts communicating in new, unexpected ways. That’s why thoughts might feel deeper, time can seem to stretch, or why that random cereal box quote suddenly feels like a message from the cosmos.
Another study published in the Journal of Neuroscience found that THC use increased activity in the frontal regions of the brain linked to creativity and spontaneous thought—but also decreased the usual filtering systems that keep our ideas in check. That combo? It's a recipe for unusual insights, strange associations, and those “wait… what was I saying again?” moments.
So no, you’re not just imagining it—your brain really is operating differently when you’re under cannabis consumption.
Why High Thoughts Feel Deeper (or Funnier, or Weirder)
Some thoughts hit differently when you’re under the influence of cannabis. An idea that might’ve floated by unnoticed during your regular day suddenly grabs hold of your full attention. Maybe it feels brilliant. Maybe it’s hilarious. Or maybe it leaves you spiraling in a loop, wondering if your fridge has feelings.
So, what’s behind that shift?
1. Your brain starts connecting dots it normally wouldn’t
THC tweaks how your brain processes information by altering salience—basically, what your mind flags as important. A study in Frontiers in Psychiatry suggests cannabis can make internal experiences (like thoughts or feelings) feel more significant than usual. That’s why a passing idea like “What if my dog understands English but just chooses not to speak?” can suddenly feel groundbreaking.
2. Your internal filter takes the night off
Usually, your brain does a decent job of filtering out the noise—irrelevant thoughts, strange associations, or off-the-wall ideas. But cannabis tends to lower those filters. It's rumored that cannabis users sometimes show an increase in divergent thinking—the type of thinking that helps you come up with creative or unexpected solutions.
That lowered mental guardrail can be a good thing for brainstorming or seeing things from a new perspective. It’s not that your thoughts are smarter—it’s that your brain is less likely to shut them down before they get a chance to develop.
3. Everything just feels more… everything
THC can increase dopamine activity, which plays a big role in how we experience pleasure, reward, and even humor. A 2001 study in NeuroReport showed that dopamine release gets a boost with cannabis use, which may explain why things seem funnier or more engaging. That’s the science behind why you might find yourself laughing at a ceiling fan or bonding with a spoon.
4. Your senses and emotions get turned up a notch
Cannabis doesn’t just shift how you think—it can also change how you feel your thoughts. Music can hit harder. Colors might seem more vibrant. Your own internal monologue might sound deeper, more emotional, or more dramatic than usual. This heightened sensory input feeds into your thought process, making everything feel more vivid and personal.
So no, it’s not just in your head. Well… actually, it is—but there’s a reason for it.
A Thought For High Thoughts
At the end of the day, “high thoughts” aren’t random—they’re the result of cannabis interacting with your brain in very real, very fascinating ways. THC changes how your brain communicates, loosens up mental filters, and makes certain thoughts or sensations feel more important than they usually would. That’s why a passing idea can suddenly seem hilarious, profound, or a little overwhelming.
Some people feel more creative. Others get introspective. And sometimes, things take an unexpected turn into anxious territory. It all depends on your brain chemistry, your environment, your dosage, and even your mood that day.
What’s consistent is that cannabis shifts your perspective. It doesn’t make you someone else—it just lets you see things from a different angle for a little while. And whether that leads to laughter, new ideas, or a deeper sense of self-awareness, there’s value in understanding how and why these mental shifts happen.
So the next time you catch yourself in the middle of a classic high thought, you can thank your brain—and your endocannabinoid system—for the ride.
