yes I have tried it and it has gone to the point where my friends noticed it ? We were at the beach doing it and I was just talking and talking , relaxed and high and my friend says," dude you're not stuttering anymore " I realized this myself and was sort of amazed. I usually stutter when I say a story or get nervous but I was talking for long periods of time and wasn't getting blocked at all. Maybe it's the fact that you feel more relaxed and calm when you're high? Or maybe the face that all my friends were high and didn't pay attention to my speech
