I knew some gas huffers in high school, but they weren't the kind to light you on fire for not participating. They were usually too busy wandering around the forrest screaming, "the trees are pissin' on me man!"

Of course in the joint, addicts are a lot more conservative with sharing their highs anyways, not that any of them paid for the gas they huffed; punishment for getting caught doing anything was usually hard labor with a chainsaw in the forrest, they always had plenty of opportunity.
