I used to smoke a bowl almost every night. I quit because it had a number of affects on me I didn’t like: (1) it made me sleep poorly. (2) it made me paranoid/anxious, as in I would become hyper focused on all the ways my life could hypothetically fall apart (3) I couldn’t manage to do much besides sit on the couch and watch tv or game (4) I would basically become paralyzed by overanlysis, to the extent that I couldn’t really talk to people.

Friends of mine smoke regularly have basically the opposite experience. It really appears to me that weed affects people in really different ways, so it’s hard to make a general statement.
