wonderful isn't it? my best mate and i find MJ incredably useful for this purpose.
when we felt 'the itch' before we would go out and get wrecked on massive cocktails of drugs; acid, shrooms, mdma, ketamine (with spliff and beers ontop). now when we get 'the itch' we just get totally ripped, like to the point where you can barely lift the spliff for the next toke and end up with half a cookie in your lungs because you cant stop laughing.
probably helps that we're getting headies rather than nasty-ass mids nowadays.
