Routes of Administration
Main article: Cannabis consumptionCannabis is consumed in many different ways, most of which involve inhaling vaporized cannabinoids ("smoke") from small pipes, bongs (portable version of hookah with water chamber), paper-wrapped joints or tobacco-leaf-wrapped blunts.
A vaporizer heats herbal cannabis to 365–410 °F (185–210 °C), causing the active ingredients to evaporate into a vapor without burning the plant material (the boiling point of THC is 390.4 °F (199.1 °C) at 760 mmHg pressure). A lower proportion of toxic chemicals is released than by smoking, depending on the design of the vaporizer and the temperature setting. This method of consuming cannabis produces markedly different effects than smoking due to the flash points of different cannabinoids; for example, CBN (usually considered undesirable) has a flash point of 212.7 °C (414.9 °F) and would normally be present in smoke but not in vapor.
Fresh, non-dried cannabis may be consumed orally. However, the cannabis or its extract must be sufficiently heated or dehydrated to cause decarboxylation of its most abundant cannabinoid, tetrahydrocannabinolic acid (THCA), into psychoactive THC.
Cannabinoids can be extracted from cannabis plant matter using high-proof spirits (often grain alcohol) to create a tincture, often referred to as Green Dragon.
Cannabis can also be consumed as a tea. THC is lipophilic and only slightly water-soluble (with a solubility of 2.8 mg per liter), so tea is made by first adding a saturated fat to hot water (i.e. cream or any milk except skim) with a small amount of cannabis.

Famous quotes containing the word routes:
“The myth of independence from the mother is abandoned in mid- life as women learn new routes around the mother—both the mother without and the mother within. A mid-life daughter may reengage with a mother or put new controls on care and set limits to love. But whatever she does, her child’s history is never finished.”
—Terri Apter (20th century)
