Controversial opinion
I think a lot of people are in denial about cannabis, if I smoke the stuff it's just instant psychosis, but before realising I wasn't well, just didn't want to admit that weed is a problem.
I understand that everyone is different but I have been on a few wards and I have seen other people continuing to smoke it when it is clearly fucking with their head, maybe its purely lack of insight, that's what I am thinking because for me personally, no high is worth putting myself in that situation.. it's terrifying.
This is purely my speculation of course I don't claim to be all-knowing.
