I know plenty of people including myself who use drugs on a very regular basis and still manage to hold down a job, relationship, friendships, keep a rood over their head, feed themselves. Hell some of them even wash before leaving the house - who'd have thought it?
The majority of drug problems in this country are down to legislation and the media, not drugs themselves.
