Scientific Information About Herbal Vaporizers

Article by WADE AGNEW

Herbal vaporizers are an effective and safe device for the delivery of the active alkaloids contained within cannabis. The efficient delivery of THC is equal to any traditional smoking system, with virtually no exposure to any of the disadvantages produced by smoking; these are toxic and potentially harmful.

So in layman terms what is vaporization? When any liquid is heated to its boiling point under normal atmospheric pressure; for water 100 degrees C, the molecules of the liquid are energized sufficiently to unbind them. When this occurs they escape the liquid state in the form of individual molecules of vapour until none remain. For water or other liquid this is referred to as "boiling". Each different solid substance needs different temperatures and amounts of applied heat to completely vaporize. This is known as the "latent heat of vaporization" for that substance. This demonstrates the concept of vaporization, and suggests that you need to experiment with not only different temperature settings on your vaporizer, but also the duration those temperatures are applied to the herbs, to achieve the optimum result.
The manner that heat is applied to your substance, in this case herbal cannabis, varies with each particular Vaporizer design. Some employ direct or contact heating, others use convection, with a heating element remote from the herbs, using heated air drawn over the them to bring them to vaporization temperature.

In a recent 2001 scientific study by Dale H Gieringer PHD it was observed that "the primary health hazard of cannabis is respiratory damage from marijuana smoke. Strategies for reducing the harm of smoking include the use of higher potency cannabis, and smoking devices aimed at eliminating toxins from the smoke produced. The most promising alternative appears to be "vaporization", in which cannabis is heated to a point where cannabinoids are emitted without combustion". "A feasibility study by NORML and MAPS has demonstrated that an electric Vaporizer can successfully generate THC at 185C while completely suppressing benzene, toluene, and naphthalene formation. Analysis of the vapour from the Vaporizer found it delivered 36%-61% of the THC in the sample. Studies of cannabis cigarettes smoked via a smoking machine under varying conditions of puff duration and air speed found very similar efficiencies of 34%-61%. Consequently Vaporizers can achieve the desired effect with a similar amount of cannabis as smoking. Further studies are needed to evaluate how their performance varies under different conditions."

There are a number of factors that govern the efficiency of any Vaporization device. Among the most important are the following;
1. The temperature setting of the Vaporizer
2. Overall weight of the sample
3. The consistence of the mixture, clumps or ground mix
4. The potency of the cannabis
5. The form of the sample, flowers or leaves
6. The inhalation technique employed

The alkaloids held within cannabis all vaporize at slightly different temperatures, but the most effective range for vaporization is between 180C and 220C depending on the variables mentioned above. It is also beneficial to "open" the cannabis using a herbal grinder, this avoids clumps that prevent even vaporization. Most users of Herbal Vaporizers will find that the best way to get the most from any batch of cannabis is to experiment to find the optimum temperature, inhalation regime, and vaporization time for that mixture.
