I hear ya man! That is the exact reason I started growing, and truly feel that its the only sustainable way to use cannabis as medicine...and not live in the poor house because of it. That being said, I would live in the poor house in order to continue to treat my condition with this plant. I've been able to come off 7 prescription medications because of cannabis, and only need to take a few pills in the evening for sleep (although I am always on the lookout for heavy sedating strains, with hopes to no longer need these last two pills!!).
