Docs are right with that while you are smoking pot they really can't tell how their drugs are working on you. Cannabinoids are anti-psychotic, anti-depressant, and anti-anxiety. THC is ... well... Let me say I have two friends with epilepsy, and one would go into grandmall at a wiff of smoke, while another uses pot as the only epilepsy control after the pharmaceutical anti-epileptics messed him up really badly, one worse than another. And when he does not have a puff first thing in the morning before he sits down and starts checking the stock market will likely seize, fall of a chair and have another nasty concussion (I once suggested that if he refuses to smoke before sitting to a computer he should at least put a bike helmet on, and maybe even strap himself to a chair). But remember the other one who gets grand malls from some smoke or a bite of brownie? Do you get why your docs want you off this stuff? It just creates one big UNKNOWN.

You may want to try reducing how much you smoke, and be consistent with it. That already may change how your prescription drugs work. Don't need to get stoned all the time, it's all up to you. You must have had moments when you decide you had enough for now, so negotiate with yourself to decide so earlier.

And it sounds like your friends really, really care about you, trust that they will help you.
