I wonder how many who post or who think that smoking cannabis is a harmless pastime. In my psychiatric nursing days, we had to look after many many drug addicts. Many admitted starting on the weed and progressing to harder items. The treatment they received depended under which consultant they were admitted. Some consultants used methadone as a means of weaning their patients off the hard stuff. Others believed in "cold turkey." It is not pleasant to watch some poor bastard crawling on the floor and screaming "for God's sake give me something - I'll do anything you want, even lick your shoes." Any more horror stories? - I've got plenty.
