I think I might have caused my friend to relapse into their xanax addiction.
How do you think you did that?
I talked about taking xanax for my anxiety because I forgot that he used to have a problem with them.
It's not good that you mentioned xanax to your friend that used to be addicted to them. You could have possibly put him on a destructive path.
What do you think I should do?
I think it would be good to check on your friend to make sure that he hasn't relapsed. If he has relapsed, then you should talk to someone who is able to help him out.
