I think what they mean as "vunerable", is a young, teenage mind, is not fully developed yet, and maybe smoking MJ, which does slow down the brain cells, interupts the final growth stages of the young mind. It may interupt the growth process of the mind, and maybe that warp your brain, or "twist", mix things up in a young persons head.

That's what I think anyways.
Nochowderforyou Reviewed by Nochowderforyou on . Just been reading about cannabis. Just read the news article from the homepage of this site about young people who smokes MJ alot have more of a chance of developing psychosis and the other one scitzo whatever. A few questions its says vulnerable young people, what do they class as vulnerable? A history of mental illness? Also the article says adolescent. What is classed as adolescent? I am 18 does that mean I am still adolescent? WHat is classed as "heavy use"? Everyday? Couple of times aweek? Rating: 5
