Take a ativan before you smoke! after you have smoked one and there is no paranoia it will probably go away. Try strawberry cough it might help you calm down more and also remember that paranoia is always in your head . And part of the buzz from cannabis is all in your head , mj does not make people freakout! people make themselves freak out!!Nobody overdoses on cannabis so why worrie? The worst thing that can happen is falling asleep! so hang in there!
