I've smoked regularly for over 10 years and just recently stopped the past month to pass a urine test for a new job. I have always told people I don't dream BUT since I've stopped, I've been having vivid strange dreams every night. I have come to the conclusion avid smoking keeps you from dreaming. I've also had tingling sensations that are irritating in both legs from knee down every night since stopping. I definately feel MJ has medicinal purposes.
