Have you tried needles? Heroin will make you fly high for days before you die. You can always switch to it from pot later on.

What I'm trying to say is that it's your life but that path is a risky one and if you are really looking for progress I'm afraid you may not find it at the end of it.

Meds are not so bad and you can manage its impact on you with a helping hand from a professional. If you're interested in my opinion I'd say go for meds rather than "smoking something to make me feel better".
