I miss weed, if it was cheap, and legal, I would smoke it every day, like I did for about thirty years.
As far as performance enhancing, I can see how you can get into the zone with it, heightened sensibilities sort of thing, and I have been the runner at a few games of country footy, where I took a joint out with the drink bottle, for the guys who liked to toke up while playing.
They were some of our best players too.
My personal experience is limited to surfing, snow skiing, and rock climbing high, and you definitely could get too bent to want to take on a grade 26 wall at horsham, or 15 foot waves down south, but you would have to be really, really wasted, just nicely baked and you get right into it, and perform, very well, often it feels like you are performing better, but there is a degree of subjectivity to those pursuits which makes that determination not totally reliable.
Flippin holier than thou baskets, just legalise all the sh1te that people enjoy, drinking, druggin, sexing it up, gambling, you know, the fun stuff.
So long as you are not hurting anyone else, then why the hell do they care so much that they want it all banned?
