I have to admit that the big druggies I know (and knew..) were much the opposite. We all have our problems of course and they are all relative. Some wanted to be rock stars and had the drugs and hellraising bit and I suppose the talent too, but just like Pearl the Singer, they never made it. Others just think it's so fooken cool to take drugs. The having a hard life bit then becomes a self-fulfilling prophecy.
I wonder do people who have been in a war zone, lost family to the war, seen horrors and I mean real horrors, lost home and everything else, etc, etc. Do majority of them become heroin addicts? I s'pose some do, but I wonder if they come to a drugs party on the streets of UK what they think of the reasons our druggies became druggies? I know some of them, the worst I have heard is "My Mum died and my life went down from there". That one was from a forty year old man on the streets of Leeds.
ETA just thinking, in fairness he could have been 14 when that happened, but even so, I bet he had never even heard of say, Gaza.
