I'm looking for the most economical/efficient way to smoke weed. I currently use either a bong or a pipe when I smoke, and I understand the bong is the better of the two. Lately though, I've been wondering about vaporizers. I've heard a lot of mixed opinions on them. My friends say its the best way to smoke pot, but i've heard others say that they aren't all they're made out to be. Could you guys offer some insight on this?
