I suppose I`ll add in my two cents on this for what it`s worth. Yes I smoked my share of weed in college back in the 70`s. Drank more than my share of beer too. Like alcohol, weed is a mind altering substance. It changes your perception of reality. You THINK you`re more creative when you`re high. You THINK you might sound better when you`re drunk. Kind of like everyone thinks they`re a badass at 1 AM in the bar after they`ve downed a six pack.

The reality is that you`re not. You`re NOT playing better, you`re NOT more creative. You just percieve that you are. If you have to get high to relax before playing guitar then something`s wrong. Just playing should be relaxing enough. Mastering a new song for the first time should be enough of a high.

Enough pontificating. Just my opinion. As long as it`s legal folks can make their own decisions. Play on.
