Smoking While Manic

I smoke cannabis for my back and cptsd but I have now realized it effects my biplor side. I don't know what to do because it helps me the most with my back injury. Even muscle relaxers didn't work. I tried quiting for 2 days and during then I was Manic and my mind was completely quiet. Well 10 mins after smoking my paranoia and insecurities have been flowing back. God I hate having these conditions 😒
