In an increasingly health-conscious (hopefully and politically correct society, people increasingly 'vape' their cannabis.

Keep in mind that a vaporizer doesn’t actually create smoke. Instead, it heats up the cannabis / otehr stuff to a correct temperature, just before combustion, and then it releases active chemicals for you to inhale, without the carcinogens and tar of regular smoke.

Vaporizers are helping people avoid the health effects of smoking and also prevent the typical drug culture associations evoked by joints, psychedelic pipes, dorm room bongs, and such.

Vaporizers have also become useful people who have been prescribed medical marijuana for health reasons.

Despite many state laws, federal law still prohibits any sale, use, or even possession of marijuana, if for questionable reasons.

The best portable vaporizer: Grenco Science G Pen Elite (easy to use, precision controls, a clear display, and Micro-USB charging)

The second best vaporizer: Vapium Summit (tough build, shiny LEDs)

The vaporizer with good air: Arizer Air (great price, bare bones)

The best vaporizer upgrade: Storz & Bickel Crafty (delicious, complex flavors, pricey, complex controls)
