THE BOX VAPORIZER
The first and most common vaporizer is the the box vape. These are the cheapest and can be found on ebay for some great deals. In fact most come with things like free grinders or scales with your purchase. The only down side to these is that they aren't made to last... Most are made in China and the screen/tubing will need to be replaced from time to time (more on that in another sections).
The Volcano Type Vaporizer
Although there are clones of the Volcano (cheaper versions) these seem to be one of the most affective ways to Vaporize! A bag is attached and the machine automatically heats the bud and then releases the THC in the detachable bag. This is very convienent as the bag can be passed around and shared. Volcanoes can cost a pretty penny though (400 to 600$) they are worth the price and very reliable (volcano brand).
Portable Vaporizers
Portable Vaporizers are a handy lil gizmos to have. Unlike all the other styles of vapes, these babies are cordless and can be taken with you to get that vape session in on the go! They are pretty reliable and priced reasonably on places like ebay. Sneak it into a movie theater and take a trip!
