.................................................. HUGS

Thinking of you !

Calm down let others do the work for you don't try and do it yourself you will only get into trouble (been there done that not worth it), Call the police inform them of the drugs explain you have mental health issues and that at the moment you are in a deep depression and can't get him to stop using drugs in YOUR apartment......

Tell them where his 'things' are and leave it up to them.

In the meantime keep your head down at a friend or families house for a few days.

The rest is not your problem its his.
