I knew one preacher man who had been a drug addict, got locked away for some crime he committed while under the influence and when he came out he often went to preach to his friends in pubs. And it wasn't long before he started drinking again. It's very easy for someone who is overconfident to take unnecessary risks and end up slipping. What do you think? Should a recovering addict be always terrified of the drugs [they used] and stay away from people who use them "forever" if possible?
