If you don't know that second hand smoke from weed gets you high, then you don't know shit. It must have some THC if it gets you buzzed at least. By the way, this isn't some new and innovative way to ENHANCE effects of weed. All this is is a method to get ALL your money's worth (literally) and to eliminate some of the odor. Just huffin and puffin alone gets you light headed...so maybe there actually is a little extra kick to it. Stop bein a hater dawg.
