Yeah, unless youre inhaling THC vapor from a vaporizer, the bag method is not a very good idea. BTW, I smoked out of a voporizer for the first time yesterday afternoon. It's so cool, it blows all the vapor into this big bag and we just passed the bag around. I got SO stoned. I'm pretty sure it's the most stoned I've ever gotten by inhalation. I was starting to trip out and see double. There was stuff shaking all over the place. But it was So good. I need to get me one of those.
