Yeah, @asdf420, CBD is hardly "inactive". But not in a cannabis sort of way. Almost like a benzo. And it sure reverses a lot of THC effects in seconds, wow. It's probably thanks to the many constituents pulling in different directions that vaping cannabis flowers causes no rebound when not doin' it. But I suspect we're in for some rougher water when people are selectively taking huge doses of isolated substances, like THC -- maybe even CBD. The tree-huggers may be right after all, stick to the God-given flowers?
