It is true, but these people usually just decide to stop doing cannabis by themselves, and then the problem is solved.JJScorpio said:I know people that can not smoke because they get paranoid and have anxiety attacks.
Those who do not stop smoking even when it makes them feel bad had some kind of mental problem in the first place, it is maybe a manifestation of some kind of self destructive behaviour or s.th. like that. Why else would you keep puffing when it feels unpleasent and makes you paranoid?
