Psychosis from cannabis use destroys lives
Having worked in Jamaica for 31 years, I am unfortunately well placed to comment on cannabis ('The truth about David Nutt').
I see many addicts, and motivating them to stop is as difficult as motivating tobacco smokers. I also see many young lives ruined by psychosis.
For many users, cannabis is only moderately dangerous through its adverse effects on motivation, driving, COPD and lung cancer.
But for the youths who become psychotic it is devastating - a living death to all their dreams.
This is the reason cannabis use should be discouraged.
Making cannabis use criminal of course does little to dissuade, but I am convinced that cannabis is more addictive than studies suggest.
