I knew military cats that would dry out old chew in the sun and roll it up, and that's how they'd cop buzzes while out on perimeter in Iraq or whatever they called that shit they had to do. Said they'd get pretty faded for a good 15 minutes just off smoking dried chew. I've never smoked chew, myself. But, everyone I know that's tried it says it kicks you in the ass a little bit just by itself.
