that, and the increased amounts of dopamine flood the receptors, effectively downing them and making it so you can't become naturally happy as easily
Wait what the forget.
Lemme go point by point through this stuff while I'm sober. I have literally done hundreds of hours of studying on the medical benefits and negatives of marijuana and other drugs. The reason I'm unable to actually talk to Aph about this is because he's not willing to listen. He's already got his mind set that marijuana is this awful thing, so there's no reasoning with him. I'm not offering nor forcing him to smoke cannabis, I've tried to discuss it with him, but he doesn't care what I have to say because I'm a burn out stoner who will never blah blah whatever. So forget that kid, not going to bother.
Dodger; where the forget did you get that half-baked information? That literally sounds like its out of a 1963 anti-marijuana ad. Adding cannabis to your listening experience allow you to experience different parts of the music that an untrained ear would not normally hear. Your audible receptors become more sensitive, so you hear it in a more "HD" way you could say. Your next experience listening to music won't be sub-par, because frankly, it doesn't do anything to your audible receptors. Marinuana raises your ears sensitivity a bit when you're high, but it doesn't prevent you from enjoying it sober. Not to mention, after you sober up, you pretty much forget what you heard, and so music just sounds the same, lol.
In regards to the dopamine; since I doubt you'll listen to me, you should read this thesis done by a real scientist who actually ran the tests.
