I was at one time an avid user/grower, it was the only thing that allowed me to relax enough to get to sleep at night. It also gave me the pain relief needed to have sex where I actually enjoyed it without the fear of having a giant spasm. I eventually gave it up when my kids were a little older but now if I had the chance I'd do it. I hear it helps with depression too. I don't think I'd enjoy paying for it though since I always grew my own hydroponically.
Peace,
Steve
