Well I dont see that smoking pot is going to be a performance enhancing advantage over any other racer, like Cab says, not good on the reactions. I've been to almost every meet at our local track for the past 30 years, i know who participate & who don't, I dont see any What The F type driving on our track from the regulars, only newbees giving themslves a crash course on racing. I thought it was kinda bizzare thing to do, but then maybe it happens elsewhere which is why i ask. So you can say it's not common practice in the US?
