You are lucky bud will do it completely for you! I pray things stay that way for you as you age. It's always best to use the least possible of any substance for relief of any symptom. Pot took me off over 100 mg of Morphine/day. But I had to gradually build up to it to experience that pain relief.
@cannabineer produces the concentrates from my grow. He uses Hexane right now because of it's temperature properties but Butane or any other appropriate solvent extraction when done correctly produces a safe and effective product. When larger amounts need to be taken concentrates can reduce irritation on the respiratory system from smoking or vaping.
Best of all the distillation decarboxylates the end product so it's immediately mixable for edibles.
However at no time does he 'blast' butane. This is all done in laboratory glass with a Ph.D. glass jockey. After watching him I'm surprised more people don't blow themselves up. I'm left with a wonderful pharmaceutical grade product. It's a dilemma and I've been on CN about writing an amicus brief. Where do you draw the line? Who should do this? I am afraid I have more questions than answers.
