Hal, dear, you need to take a Chemistry class! THC is not mostly water. Heck, THC can't even disolve in water! (This is why pot tea won't get you very high.) But back to the topic of vaporizers, I love mine. I've had it for about 2 months. I got a little Vapor Brothers GNES Hands-free model. I use 1/2 the pot (it will pay for itself in no time), MY LUNGS ARE CLEAR!!!, the brownies from the duff are kick-ass, and kids,there is virtually NO smell! I picked mine up from discountworldonline.com for under $140 with about $14 for S&H. I got good service- a receipt and a shipping notice the next day,and their service was prompt. (They must love me by now for all the free advertising. LOL) Really, kids, I've been using cannabis for 40 years, and getting the VB was one of the best things I've done for myself ( getting my medical recommendation was #1, but this isn't far behind!) Right now about half of you are out of pot- the normal late summer drought- if you bought at the same level as you do now, but used a vaporizer, you'd likely have a nice stash to tide you over. I do! :thumbsup: Health, stealth and wealth- all with a vaporizer. Granny has spoken!
