People don’t always understand or sometimes deny side effects of pot because it’s not always noticeable right away but long terms are many and they are bothersome especially for young people. Personally I’d never live with pot smokers. It will be either me or pot. And I am out if it’s pot.

Sadly you can only control yourself. You can’t make people stop their habits

I recommend therapist for yourself actually you can do Al Anon because it’s not just for alcohol.
