Lol @ the people thinking weed can't make you trip or cause psychosis. You obviously haven't smoked enough. I've had time dilation, thought loops, open-eyed and closed-eyed visuals and complete hallucinations, synesthesia where I've seen sounds, I've watched the entirety of existence become a layered 2d landscape, I've done the ego-death thing, heard the most celestial music coming out of a bag of chips, all kinds of crazy shit.
Referring to CNN articles about "Can weed make you trip" is about the funniest thing I've ever seen.
Also, rehab for weed is hilarious too. She didn't go to rehab for weed, she went for psychosis, which is common with pot. Zillions of case studies, longitudinal studies, personal experiences and self-reports, etc. will testify to that. It's not even an argument. You either accept the reality or you don't. Weed is really bad for some people. And it's the bomb for others.
Everyone is an individual with different physical, genetic, psychological, biochemical, and neurological make-ups. To act like any one position is a catch-all is retarded, especially when it has to do with a psychoactive drug. You guys DO realize what psychoactive means right?
