I dont have a vaporizer, but I'm going to get one soon. After reading so much about them, they are deffinately the way to go. If you ever get in a debate regarding legalizing marijuana and your advisery brings up the fact that cannabis smoke contains harmful carcinogens, tell them to vaporize man. Here is some information I found while researching medical marijuana. http://www.mikuriya.com/can_vapor.html This is from the web page of Dr. Tod H. Mikuriya. Dr. Mikuriya has spent the better part of 50yrs, basically his entire medical career, researching and advocating medical marijuana. This is awesome, it even has a realplayer video on how to properly vaporize! And after you are done with that, take a moment to review his entire webpage. He truely is a remarkable man. And here, Marijuana, I have uploaded a study conducted using the Volcano Vaporizer that demonstrates vaporizers effectiveness in delivering cannibinoids without having to inhale harmful toxins. Enjoy.
