Your Brain on Drugs: Marijuana

Your Brain on Drugs: Marijuana


For centuries, humans have been using substances
to alter their state of mind. From caffeine, cigarettes and alcohol
to more extreme drugs. But as the most commonly used
illicit drug in North America, Where does marijuana fit in and how exactly does it affect your brain? First, we need to understand how the brain functions. Neurons are the cells that
process information in the brain. By releasing chemicals called neurotransmitters from the axon of one neuron
to the dendrite of another they change the electrical charge
of the receiving neuron consequently exciting or inhibiting it. If excited, the signal is passed on. Though it sounds simple
these signals work together and the effect is quickly compouned
into complex configurations within milliseconds flashing over the entire brain. This is what happens every single time
you think, breathe or move. So what is going on inside your brain
when you’re smoking marijuana? Well unlike alcohol, which contains molecules
nothing like those in our body, cannabis contains molecules that resemble those
produced in our very own brains: cannabonoids. Although naturally these cannabonoids
circulate at much lower quantities compared to the large influx imposed by smoking, specifically the chemical tetrahydrocannabinol or THC resembles a natural transmitter called “anandamide”. These cannabonoids are specialized neurotransmitters released by neurons having just fired. Neurons temporarily become unresponsive after firing to prevent them from overracting
or being too dominant. This allows your brain to function in a
calm and controlled manner. But cannabonoids interrupt this approach
in some parts of the brain. Instead, they remove the refractory period of neurons
that are already active and can cause your thoughts, imagination,
and perception to utterly magnify itself. This means, once you begin your train of thought it becomes the most significant
and profound thing ever. You can’t see the big picture
or even recall your last epiphany because you’re caught up in the momentum
of a particular idea and your neurons keep firing until a new idea takes hold
and you go off on a new tangent. These cannabonoids also affect the levels
of dopamine and norepinephrine in your brain often leading to a sense of euphoria,
relaxation, pain modulation and general enhancement of an experience, though sometimes causing anxiety. Furthermore, there are cannabonoid receptors in areas controlling short-term memory,
learning, coordination, movement control and higher cognitive functions. Got a burning question you want answered? Ask them in the comments

  1. How many of the boys are out there watching this high asf because it popped back up your recommended because YouTube’s algorithm is trash lmao

  2. Does smoking it once or twice in a month? Has any effect on brain in the long term, like effect on learning, decision making, studying etc. Plz give a answer to this question, and btw i am 22 years old and i am heavily addicted by marijuana , and now i want to cut it down to 1or 2 joints a month..please reply❤️

  3. First time i smoke weed when i feel hot in my body hot tasted like tomato i don't know how can i explain i hope you understand what i said

  4. Me *sees video*finally many ill have an excuse to do dope (for legal resons this is a joke)

  5. I'm gonna start writing a diary every time I get high. Some of the stuff I come up with needs to be archived.

  6. Just a reminder: E V E R Y T H I N G has risks, even water, even a spoon, even a paper towel, everything can kill you if you use it wrong, in the wrong situation, overdosing, etc…
    But weed is so much better than things that are legal is almost every, if not every single, country in the world like alcohol and cigarettes

  7. Why do people get depressed high when they smoke weed? The other night I smoked and I couldn’t stop crying because I wasn’t happy high and my dumbass thought hitting a candle on my head repeatedly would make me pass out. Did dopamine not get released?? I’m so confused

  8. If you are under 25 do not smoke. It will mess with the brain. Your brain is still developing and you don’t mature until you are 25. If you drink or take drugs as a teen you are more likely to get depression and have an underdeveloped frontal lobe. But if you are over 25 light that shit up

  9. Can you please upload more about where the locations of the brain and long history with (the blat) marijuana

  10. I recently started smoking weed and ive noticed that ive completely just lost my appetite. isnt it supposed to be the other way around where you get extremely hungry?

  11. I tried it once and it felt amazing when it hit and I loved how it made me laugh but as soon as I started the laughter fit my heart rate picked up… and from then on for the agonizing remainder of the high I just felt anxious and scared… I guess it was just too high of a dose (this was my first time and it was edibles) but yeah..

    Anyway several times later I tried an Indica oil (around 2mg thc) and I didn't have any physical problems but it's been very unpleasant to say the least. I wouldn't use the word "anxiety" or "paranoia" but just very very boring feeling and also a "speedy" feeling.. But not speedy in a euphoric, fun or even constructive way.. Honestly I was just waiting for it to end because it was very unpleasant, not scary or anything but just very unpleasant. I'll give it another go since it's obviously this amazing plant but it hasn't shown me much reason to, not even a redeeming quality..

  12. Used to be so scared of marijuana in primary school when teachers were teaching about bad drugs… Damn look at me now

  13. When I got high for the first time, I was only 18 and got so paranoid since everything around me became stretched and started spinning in a weird manner
    And my body felt like it was in another dimension and like I didn’t have control over it
    I got so scaredd
    And I didn’t get the high that everyone enjoys and make them laugh and shit
    Mind anyone explain

  14. I put a camera in my room and house when I got high (I live alone so ye) and when I wasn’t high anymore I re watched the footage on the cam and the shit I said and did lmao

  15. This is my first time getting high and this video explained all of my questions. Its an experience for sure

  16. all the kids in the comments sayin weed is completely harmless. Addiction to it IS real, i was there and trust me its not a joke

  17. I watched this before getting high and now I'm rewatching it while high nd believe me I can hear the letters laugh

  18. So beware smoking marijuana? This video tells us that when we are high neurotransmitters are basically working overtime instead of resting when overworked like how they do when sober. So I’d imagine becoming a heavy stoner means your neurotransmitters are always at rest when sober and only really super active when high. Good way to beat this could be longer breaks between highs maybe…and shorter high times with longer sober times. Basically smoke less 💨

  19. Is it normal that my eyes, eyebrows and tongue moved by itself repeatedly? Cause i did this when i was high

  20. Smoking weed can kill you faster as the cigarettes? And how this plant affect your lungs and your body when you are smoking it?

  21. It's interesting that he stressed the second syllable in 'cannabinoids', I'd always stress the third. I wonder if that's a difference between American and British English pronunciation.

  22. When I'm high I just feel I'm spinning in circles and my body feels so relaxed it feels so good and than I sleep. Lol

  23. Should of put there that its an enhancement.. And a mineral. That slows the growth of cancer cells from forming… And if you are pregnant you can smoke organically with valcano or zero butane..
