Go on a walk. Share a secret. Tell each other something you really like about each other. Cook. Build something.
Many drugs often end up being an excuse to socialize and experience something significant together, but lots of non-drug things can do the same work (even if they're less "cool" to suggest).
There are support groups, but accountability and understanding from true friends. Help him set tapering goals and he needs to understand what he will go through - vivid dreams coming back, fierce at first, etc. But support from those who have done it.
What does he smoke it for? Pain, anxiety, just the high?
I tried pot once and it was not for me, but I know folks who use it, and they have different reasons.
Also, is it legal where you are? That tends to ensure that he's getting more consistent pot (which would mean better being able to be sure of what effect he's seeking/getting).
Not doing drugs.
I smoke Hashish + Tobacco now and i've been doing drugs since i was a kid, it takes it's toll.
Rn i want to stop but my girl don't. I don't have that self control to not smoke and be just watching (and smelling).
Anything can get you addicted and be a problem.
I used cannabis too much to escape reality when i was a kid, now it's very hard to stop it.
I stopped using cocaine but can't manage to quit tobacco or THC.
What do you mean better then coke?
At first coke was cool and i wanted to be with people and have sex, then after a year i don't even cleaned the house anymore, would not eat for entire weeks, be tweaking, paranoia, panic when i set foot on the streets, etc...
Don't get me wrong, you and me both know people can function on drugs, but it still drags you down. I found out i can enjoy life and it's things with no drugs after i sorted out some things...
