How do I help my boyfriend get off pills??

Bring him to professional help. that is my advice

The problem is the friend that's getting him to do it. Peer pressure is one of the major reasons people get into drugs in the first place, so you'll have to try to get him to stop hanging out with the friend, but you have to be subtle about it because if you make him choose between the two of you then you might have a problem. Then I suggest that you try to find out why he does it apart from peer pressure, does it relax him, excite him, etc. Then once you find out what that reason is then you can suggest activities to replace the sensation, for relaxing I suggest having him try yoga or meditation, you can learn it together to help strengthen your relationship and to give him greater incentive to quit. I hope my advice helps! Good Luck!

Wow its great you guys have that trust. First of all he needs to explain to his friend that pills are not for him and he doesn't want to do them anymore. If his friend gets it then great and if he doesn't get it then he's a pretty shitty friend. Get involved in a free anonymous support group. depending on the pills, google your city for narcotics anonymous. They can really help him get a handle on things, and give him tools and steps in a good direction.

Seems like the hard thing for him is confronting his friend. Maybe if he can explain what has happened to his father and that he doesn't want to go down that path, the friend will understand.

Keep him around the more he's around you the less time he will spend on the drugs

Another thing that worked with me and my cutting is when my boyfriend threatened me. Well he threatened to start smoking pot again. If he really cares he won't want you to do something bad and he will quit. He will probably start doing them less and less that's what happened with me

Hope he quits and hoped this helped
