Best way to talk to a friend about addiction?

[Danzig]

i would bluntly tell him you're not able to give him funds to pay for his habit. but, til HE recognizes the problem and wants to change, nothing will get him to quit. i'd imagine his mother probably already realizes something is up. but there's really nothing you can do. he has to do it.

My best friend killed himself due to an addiction... I wish I would have said something to him when I had the chance....

I suggest trying to talk to him if you can and the sooner the better.
