You should convince him what he is doing is bad for him.. his health and everything else.

Lesliedean, You are probably not with the right guy... he sounds a lot like me and I wouldn't worry too much about him as I would you.  He's doing things that are hard core and absolutely irrational, stupid, irresponsible.  I have done many things like him and should be dead but always managed to come backBack pain - low
Back strain treatment with a smile... It was sooo selfish of me because I never thought about the people around me... It was easy to do to me!  I'm so surprised that he is doing THIS in front of you???  It's a mind scrambler!  I can’t imagine that he has a lot of respect for himself let alone you?  Maybe Get out while the getting out is easy, and that is easy for me to say. I know what it means to love someone.  Love can concur all but it can also blind all.

I was not normal when I was doing those kinds of things.  It sounds like you are reasonably normal.  Do you want a normal life?

Drug-induced hypertension hit faster but not last as long.

And from those I know that do it, bloodyBloody or tarry stools nosesNose fracture and such should be expected. Not a good thing, and that's from people that do it (not I, I'm too scared to do that or shoot up).

Good luck with him. Are you trying or have you quit yourself? If so, you don't need to be around people using. Plus, think how bad yop'd feel if you have quit, or are quitting, and you get arrested just because you were with someone else using/buying?

Normal people honestly take by the label and their doctors intructions.....

Addicts crushCrush injury them and snort them there is a huge difference....

Did you ever contemplate crushing any meds your doctor prescribed then taking  a straw or a dollar bill and snorting them up your noseNose fracture???????
