Cannabis, does it help?

Cannabis, does it help? Seriously don't just judge me for my username. I started smoking when I was 15 and my previously severe stutter kind of just fell away. I am a habitual smoker and have been for years and it certainly helps me. On a similar note, I had a two month period recently where I was taking 10-30mg of valium every day. I had no stutter whatsoever for this period. When I came off it, suddenly I was back to the paralysing affliction we all know and despise.
