Understanding Vaporizers

By Robert McGregor

Are you worried about the bad effects of smoking? Don't you wish there was better way to get the beneficial ingredients of herbs and other plants without swallowing bitter pills or having painful injections? If you answered "yes" to the above questions, you could benefit from a vaporizer.

A vaporizer is a device that extracts and releases the active ingredients of plants and herbs. This is done by heating the material in a partial vacuum so that the active ingredients boil into a vapor. The vapor is then extracted through extraction chambers made of metal or glass. The user gets the vapor by inhaling a hose or pipe. The remaining vapor is stored in a bag or jar for further inhalations.

There are three types of vaporizers - thermal conduction, convection or thermal radiation. These types refer to the way the substance is heated. In thermal conduction, the substance is heated on a metal plate. These were the first types of vaporizers. In convection, hot air is used to heat the substance. This works faster and releases more active ingredients than conduction heating. In thermal radiation, the substance is exposed to bright light, causing a rise in temperature that releases the active ingredients. Such vaporizers are rare but are as good as convection vaporizers.

Because there is no combustion or burning in vaporization, there are no smelly or poisonous fumes. Unlike smoking, the vapor doesn't have combustion byproducts like tar and has a low percentage of carbon monoxide and other cancer-causing elements. This also lessens the dangers of secondhand smoke. Being colder than smoke, the vapor won't irritate or destroy the lungs and throat.

Vaporization is also superior to other drug delivery systems like pills or injections as well as smoking. Here's why: aside from being painful, injections can spread diseases through contaminated needles while pills can be affected by digestive juices and take time to work. Of course, we all know the harmful effect of smoking.

The effects of vaporization are immediate since vapors move faster and are quickly absorbed into the bloodstream. Because it is pure, less of the vapor is needed to mimic the effects of conventional drug delivery systems or smoking. This contributes to the precise delivery of active ingredients with the least side effects. These qualities also make vaporization a better choice than smoking.
