Here graft is like illegal work usually, you know selling drugs on a round for someone, selling knock off designer stuff, being the gardener for someone's crop, right up to burglaries and armed robberies.
I attend families anonymous, there is no NarAnon in the UK. It's mostly mums of addicts but to me addiction is addiction and I get a LOT out of attending the meetings and working the 12 steps with my sponsor. Even just having a friendly understanding voice on the end of the phone. My ex is a heroin addict, we're not together any more but I'm still trying to put my head back together after almost 4 years and a child together. You can look online for a meeting, try here

Or there is a forum which will help you find a meeting too.
