I suppose that the "lead" feeling I get isn't from THC, but from the smoke i've sucked down. Perhaps vaporizers would work better, but honestly, I doubt i'll ever get one; if I have to choose between buying a sizeable amount of weed and something with which to smoke, i'll stick with the first option.

I bought a bong for $30, and, although I figured it was a rip-off, i've saved probably double that in papers. The money is small, but it does add up.
