<human>: Before I met my boyfriend I knew he was into drugs.  Then, word was that he had stopped doing drugs from anxiety, and I thought that was pretty neat. 

When we started dating he started feeling better about himself, and his anxiety had gotten better, so he started smoking weed again.  He said he didn't want to smoke as much as he used to.  Progressively over a month he's started smoking almost everyday with my bro and his friends.  He also binge drinks when he drinks, mostly beer.  He takes random pills I don't even know the name of, some include xanax and ambien.  He also has started smoking cigarettes again.

I'm not a big drug user, will only drink beer occasionally and weed is whatever.  I know he's not a drug addict, but compared to me is.  Being around drugs make me uncomfortable, and I really love him when he's just sober.  That's how the beginning of our relationship was like, unless he just didn't tell me.

I don't know what to do. I love him but I feel like the drugs are just unnecessary and it pains me to see him fucked up sometimes.  I know it's not my business to say "hey no drugs!" and I wouldn't leave him unless it got to addiction status. I'm just fearful for him.

How can I express my concerns without coming off as nagging?

Can you give me the gist of the text in a nutshell?
