If you are interested in living a healthy lifestyle than you should know that vaporizing won't damage your lungs like smoking will
Vaporizing is hands down the cleanest and most efficient way to enjoy your herbs. Vaporization consists of heating the herbs(not burning) and blowing the resulting vapor into some sort of bag or container. The vaporization process actually saves you from all of the carcinogens in smoke by gently heating the herbs instead of torching them.
A major difference between vapor and the smoke, is the freshness. The vapor will stay fresh for the entire smoking session and will not become stale like regular smoke would. When you use a flame to smoke you are burning carcinogens and unwanted plant matter that has ZERO effect besides damaging your lungs. After a homemade vaporizer session the herbs will be brown and and stripped of their active chemicals, you can treat it the same as ash.
The flavor and aroma from vaporizing is a one of a kind experience that all smokers should have and those who haven't I am sure would like to. Obviously I'm an advocate of trying to make a homemade vaporizer vs buying one, and if you see how effective mine is you will feel the same way. The volcano is $600 which is a little ridiculous, let's make homemade vaporizers and hopefully they will either go out of business or drop the price. If you smoke the health benefits of vaporizing are clear but which vaporizer to choose is another tough decision. Whether it is a volcano or homemade it still beats the classic Bic lighter any day of the week.
