DON'T SMOKE Marijuana;
The usual irritating and toxic breakdown products of burning utilized with smoking are totally avoided with vaporization. Extraction and inhaling cannabinoid essential oils below ignition temperature of both crude and refined cannabis products affords significant mitigation of irritation to the oral cavity, and tracheobronchial tree from pyrollytic breakdown products.

Cannabinoids- Inhaling Safely
non burning ingestion of active principles
usual irritating and toxic breakdown products of burning utilized with smoking
are totally avoided with vaporization. Extraction and inhaling cannabinoid
essential oils below ignition temperature of both crude and refined cannabis
products affords significant mitigation of irritation to the oral cavity,
and tracheobronchial tree from pyrollytic breakdown products.
first described vaporizing cannabinoids in the 5th century BC:
Scythians then take the seeds of this hemp and, creeping under the mats,
they throw them on the red hot stones; and, being so thrown, they smolder
and send forth so much steam that no Greek vapor bath could surpass it.
The Scythians howl in their joy at their vapor-bath. This serves them instead
of bathing, for they never wash their bodies with water.”[i]
cannabinoids were noted to boil at 150° - 180° C. (302° - 356° F) by Wood,
Spivey, and Easterfield (J Chem S, v lxix, 539) in the 20th Ed.
1918 U.S. Dispensatory.[ii]
oil, an extractive product from organic solvents and filtration, was described
by Adams in 1940 to boil at 180° - 190° C. (356° - 374° F)[iii]
Merck Index lists the boiling point of delta 1 Tetrahydrocannabinol as
200° C (392° F)[iv]
author first recommended vaporizing cannabinoids in 1993[v] with
the observation that vaporizing cannabinoids takes place below ignition
temperature with much less exposure to the numerous breakdown products
of burning. Vaporizers, a
video was published in 1999, updated 2002 documenting different devices

a thoroughly documented description of using the Vripmaster vaporization
device utilizing different adjustable heat guns.
2000 at the International Cannabinoid Research Society meeting Oakland
Cannabis Buyers Cooperative director Jeff Jones demonstrated a Vripmaster

Pharmaceuticals sponsored the first vaporizer contest in Redway on November

the use of thermostatically controlled heat gun devices, patients
report positive feedback regarding efficacy and prefer to smoking cannabis.
Instead of losing drug to combustion, which continues after inhalation,
the heat gun is turned off and the vaporization halted.
freedom from breakdown products of burning permits appreciation of aromas
and tastes of cannabis. Hot air essential oil extraction process from
granulated crude cannabis appears to be the most efficient and temperature
controllable. Furthermore, there are significant changes in the composition
and rate of vaporization with the increase in temperature. Delicate and
distinctive aromas and tastes at the lower temperatures change in character
and intensity as temperature increases. For product description it will
be appropriate to characterize first aroma, second taste, and psychic effects.
While the Merck Index lists delta 1, 9THC as vaporizing at 392° F, the actual subjective experience is that the vaporization of cannabinoids is a function of temperature and amount. While delta 1, 9 THC may vaporize at that temperature the other cannabinoids go into vapor phases at temperatures significantly below.
at room temperature in a bud trimming room with significant exposed crude
cannabis affects me and others not adapted to ambient levels of cannabis
vapor. With granulated crude cannabis supplemented with condensed refined
resin vaporization takes place at lower temperatures. (190 - 200° F).
These cannabis tasters would also better characterize the qualitative properties of the samples and give feedback to the provider as well as inform the customers.
addition to protecting customers it gives providers quality standards.
Similarly, all cannabis cup competition organizers should be encouraged
to vaporize the products to permit a more complete and sophisticated description
of competing products.
constitutes a salient breakthrough in cannabis therapeutics because of
safety and avoiding the other disadvantages of smoking cannabis. Additionally,
the complexities from the enhanced appreciation of tastes and aromas adds
aesthetic dimensions to cannabis products that are obscured by smoking.
Improvement of health in marijuana smokers who ingest high impurity product
in large amounts appreciate inhaling cannabinoids instead.
