I have a good friend of mine we'll call C for this, and C used to only smoke weed. It wasn't a big deal, and then he started drinking and stopped being my friend for a really long time. Then he started trying literally anything anybody would give him no matter what it was and I'm trying to become his friend and gain his trust again so I can help him because I do still care about him, I just wasn't capable of handling an addict in my life at the time this happened. How can I at least help him a little bit? His family doesn't care what he does so there's nobody I can really relay the information to, and we aren't close anymore so I'm not sure what else to do.
