lol it's bullshit. That crap was disproved ages ago and the guy who began the rumor stated it was just bs. I'm also pretty sure that that chemical has a very very very high burning/melting point... and wouldn't even be able to be smoked.
no way... my friend bought some once and i laughed at him and then we smoked a bowl of it and obviously nothing happened except perhaps a mild unpleasant intoxication you will get from smoking anything, like leaves for example, accept legal "buds" are almost expensive as marijuana. That stuff is a rip off and I still laugh at anyone smoking it trying to have an experience even remotely close to smoking the good stuff. Just my perspective and opinion.
