Well then, I guess that reading the wikipedia article on cannabinoids should do the trick  
(and if it is not enough, then I can read the referenced articles too :) )

Your first lead with be the cannibanoid receptor. Almost like a brother to the Gaba-ergic channels these largely control the amount of neurotransmitters that a neuron fires. If the brain can’t find a signal, or thinks it’s under attack it will crank up this volume.
 
Delta-THC, and CBD are the two most well known, and active Cannibanoids that you should look into, but some strains have over 50 analogs (structurally similar, usually minor differences like carbon chains or phenol rings to denote unique properties.

@Derpian  
I’m a youtube - scholar/google kinda learner.
 
Basically you can find a guy that will give you a general, comprehensive overview, and then you can search for all the little details, like analogs, other cannibaniods, metabolic halfife and all of that from articles listed by citation. Lots of numbskulls call this psuedo intellectual because they’ve never foraged the internet before or something.
 
Yeah I was checking on one of my pictures before I take a nap, when I wake up I’ll find you something if you haven’t already.

@Ninji  
This is very interesting. I guess I should read something more about that. Any particular book, article or webpage you’d recommend?

@Derpian  
Well what science can figure is THC is a precursor to plant poison. Lots of flora have trace amounts of it, including apples. Precursor means the brain has evolved to see this chemical as a warning for poison. Weed however doesn’t have toxic qualities, you couldn’t eat enough to kill yourself. It’s speculated we have bred the toxic qualities out of weed just like we bred the prefrontal cortex into dogs.
 
cannabinoids hit the receptor and say “POISON!” and neurotransmitter valves open up wider to feed the neurons, and strengthen them against the toxic threat, however there is no toxic so the brain is just pumping and feeding itself uninhibited. This increase in neurotransmitter flow makes all senses appear ‘wider’ you absorb everything much quicker, and some people become couch locked because it warps their since of phychomotor coordination, or get mesmerized by music, or they just feel incredibly comfortable.
 
This mechanic of heightened neurotransmitter release causes euphoric feelings, and often a phantasmagoria of neurons that have been cold for a long time, you will experience memories you usually never think about, and if it’s strong enough the memories can become visual and auditory, causing mild hallucinations.

@Ninji  
Do tell me more

What’s actually going on is your neurological static (random unstructured fires) becomes a lot louder. You might start feeling thrumming energy in your head because the nervous white noise is actually your brains way of feeding and maintaining the neurons. Scientific basis for this is observed in the fact that cannabinoid receptors  
are proven valves for neurotransmitter release.
 
I speculate that your brain does this as an evolutionary attempt to rebound from plant poison, and weed has the chemical precursors of plant poison without actually being toxic, this observation is purely anecdotal from my experience with other drugs I’ve felt amazing rebound from.

@monolyth  
Close enough, I guess

@Derpian  
My brain goes numb

@monolyth  
Nah, if you smoke enough you can feel the nature

That sounds more like LSD.

@Einsman  
Nop, thats nitrogen. Its, in a very small dose, what we breath. Oxygen is just breathable in a mixture with nitro, but its not because we are breathing it that we decay, its because we are exposed to it. You could put yourself in a room full of oxygen and just breath from a tank, and the first thing to go would be your skin. Because that is how it works. By exposition, not by dissolution.

Marijuana can show some decline in lung function over time, but I’d be hard pressed to think it causes any substantial damage in comparison to plenty of things we do everyday from physical exertion to our piss poor diets.

@nekonigga
 
And that 30% that we need to live is ALSO what causes our bodies to slowly fall apart.

Tree Hugger? More like Weed Killer.

@Einsman  
Like Amniotic fluid, medical mist, any tea infusion. Also, AIR, that little thingie is actually an ultra dirty compound, just 30% of what you breath is actually what need to live, the rest is smoke, dirty gasses, and a lot of dirt, so, yeah, everything you put in your lungs is killing you.

@nekonigga
 
Anything foreign introduced to the lungs DOES do damage.

@Einsman  
The smoke is actually hard gas, the lungs can with it. The thing about tabaco that damages the lungs is all the residual shit it lefts in there

@nekonigga  
Putting ANY kind of smoke or somesuch in your lungs does damage.

Never mind. The art is good, so I upvoted this after drawing back my downvote.

@nekonigga  
Totes agree w cha bro. (o3o)

@atalarikt  
Weed and tabacco are two very diferent things

Smoking weed isn’t killing yourself lol.
