I don't smoke weed anymore but I smoked for a lot for about 6 years and I think being high makes you a little more anxious socially then when you are sober. It is a drug in my experience that should be used when you are at home with a couple friends or by yourself watching a funny movie or something of that nature. But there is a small amount of paranoia and anxiety associated with being stoned and I think makes my stutter worse personally.
