as one who has smoked marijuana,.. I can say I see no effectual medicinal purposes for marijuana,..what I have experienced is a sense of paranoia in different stages, the loss of effective thinking skills in some areas while under the influence of it, and just an overall high feeling,..nothing good, nothing medicinal. hasn't helped any pain or coping with pain. I don't see how it can free-up the tensed joints from symptoms of arthritis,.. how has it really helped?
