My mate had a real drug problem

I used to have a friend who had a real problem with drugs and i've tried sum before. The best thing is not to nag him abotu it or you'll just lose him as a mate. U gotta keep dropping the dangers into conversations with him and make sure he doesnt move onto nething bigger. If he says owt like "its can be gud u know it helps people with cancer and stuff" just ask him if hes got cancer. But basically try not to nag him cos it mite make it worse, and make sure he dont get nething stronger.

I think what you are saying is the right thing to do, otherwise you will create a divide in your relationship with him. Perhaps you can bring other people around to your point of view so that you influence his lifestyle as a combined effort.
