Stupid people smoke it or does it make you stupid? Guess that depends on who you ask.
Makes you stupid. I have a friend who was a top 10 HS student, National Merit Scholarship winner and dean’s list in college. He started smoking while on campus. 40 years later he is stocking shelves at a grocery store and deals daily with deep paranoia. It has been sad to watch his descent into his present existence. When you can just talk to him the bright young guy of an earlier time occasionally comes through, but sadly those days are fewer and fewer anymore. And yes it is physically addictive.
The previous study was done over twenty years and did before and after tests.
Yeah of they are measuring gray matter, I’d like to see the before and after. I’m betting pot doesn’t cause smaller brains, I’m betting smaller brains are using pot.
