thats not worth using as a vaporizer. maybe you should start smoking meth. btw, you can make one from old lightbulbs, a 2-liter pop cap, and a straw that wouldnt cost money, but if you've already bought it whatever... anyhow, i've made those from lightbulbs before. same thing. might as well just smoke the pot, cause thats what you'll end up doing anyway when you realize it doesnt work well at all. if you can actually get vapor rather than smoke from it, it won't save pot, and it usually ends up with smoldering pot anyhow. trust me, these things suck. only good if you're into smoking chemical drugs....
^while how much is actually thc vapor and how much is more or less smoke is debatable, it gets me high with what appears to be less than normal, and without damaging health problems, to a limited extent.
