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

    So one time I was invited to a party… I was always the quiet one in school… (which means I didn’t really have friends or I never went out) and I decided to go to the party and I didn’t know there was gonna be smoking and drinking so I was just standing there doing nothing like an idiot… then there were these group of people and my one friend was in it and they invited me over… then one of the guys got something out of there pocket… and of course it was marijuana… all of them were smoking except for me… so my friend was also smoking too… and she asked me if I wanted to do it? And I said “sorry, I never tried before so idk” and all of them seemed Soo surprised I never tried so they forced me too… then, they gave me the chute (where I live we use a homemade chute to smoke weed with) and I said “Uhm idk how to light it up” so my friend did it for me. Then I did it! And a few tokes later… my eyes felt low and Fat? And I couldn’t stop laughing and Smiling… lol and I was always shaking my legs😂 idk why but it was an amazing time… then After a few more tokes my crush… (I think we liked each other at that time) invited me over to his room! And I was confused… (I was soooo high that I was confident to do anything…) and then he was rubbing my thighs… and then you know what happens after that…! And then of course I was forced to try alcohol too! Soo idk why I drank it in the first place! So I actually enjoyed it that night… and now me and my bf Kerwin are dating 🙂

    I feel at Nirvana rn lol. You see so I have a wax pen and I am a pretty experimental type guy, really! I'm like a mad scientist or something, or just a fool 🙁 BUT I wanted to test some effects on Marijuana on the right side of my brain. How so? Simple by being weird and being a lil brave and so I held the button down and snorted a little of the marijuana through the right nostril while being under a lot of stress. The reason I'm here is because it worked lol! So the area of pain in my brain was in the right side and now I just wanted to see wtf my right brain was doing now lol cause its like floating in space rn. Sorry be back soon friends!

    I don't bash Marijuana but I do bash users of Marijuana. They tend to have tattoos, be lazy as heck, and smell bad most of the time. Which are qualities that I hate. And also, they talk about relaxation but when I smoked Marijuana for the last time in 2016, I was feeling panicky. I was seeing double and my heart was beating rapidly. It's strange but I do think that Marijuana should be in every single health care/medicine facility in America for medical reasons.
