Smoking

Smoking is the most common method of using cannabis.

Cannabinoids, such as THC, in smoked cannabis reach the bloodstream within five seconds of inhalation. Peak blood levels of cannabinoids are achieved within five to ten minutes after smoking. The biggest advantages to smoking cannabis are the speed of effects and the ability to accurately gauge the dose.

Cannabis cigarettes (joints or blunts) are not very efficient, since only about a third of the available cannabinoids is absorbed by this method. Experienced cannabis smokers tend to be twice as efficient as novices at extracting cannabinoids from cannabis cigarettes.

Waterpipes (bongs) are more efficient than cigarettes, delivering over 50% of available cannabinoids. Because waterpipes deliver large volumes of smoke, the dose is difficult to gauge.

Glass pipes are the most efficient smoking method, as their small bowls encourage manageable doses. All glass pipes should regularly be cleaned of cannabis tar by scrubbing them with 90% rubbing alcohol and salt, then rinsing with water.

To properly smoke cannabis, you must both inhale and exhale normally. Studies have shown that breath holding beyond ten seconds does not increase cannabinoid absorption. Use the smallest dose of cannabis that produces medicinal effects. Wait at least ninety minutes between doses of smoked cannabis. When smoking, herbal cannabis flowers with higher cannabinoid content reduces exposure to irritating tars.
