I don't know if reefer works on pain. I know people say it does and they also say it helps with the side effects of drugs for treating cancer and other really heavy-hitters like that. I'm just doing the same thing now that I was doing in 1978. I quit drinking many years ago though. The side effects of alcohol are too much....getting arrested, lawyers, jail. That's Dr. Jekyll and Mr. Hyde. With weed, I'm like GD Gandhi...it's all peace and tranquility.
