That's the thing though, they were probably weird conspiracy theorist nutjobs WITHOUT the weed. It doesn't magically make you into one, the same way that coke doesn't automatically make you Tony Montana. Equally alcohol doesn't make you a violent knuckle dragger, but it does lower the inhibitions of the average knuckle dragger to the point that they are happy to get violent. Of course, booze is socially acceptable but recreational pharmaceuticals aren't so we have to demonise them and the ones that partake. Personally, I'd far rather be camped next to a bunch of stoners than a group of piss heads.
