While most users are familiar with varying potencies of marijuana, many are only vaguely aware of differences in the efficiency of various ways to smoke it. Clinical studies indicate that only 10 to 20% of the available THC is transferred from a joint cigarette to the body. A pipe is better, allowing for 45% of the available THC to be consumed. A bong is a very efficient delivery system for marijuana; in ideal conditions the only THC lost is in the exhaled smoke.

If that's true it should settle some controversy. I think the stat about a joint doesn't account for the residual canna-goodness that's deposited by the smoke onto the fresh herb as it passes through.


Tolerance and the quality of the marijuana both affect the balance between the two tiers of effects: the coordination problems, short-term memory loss and disorientation associated with the term "stoned" and the pleasurable sensations and cognitive stimulation associated with the word "high." The distinction between the two states is nothing unique. Alcohol, nicotine and heroin can all produce nausea when first used; this symptom also disappears as tolerance to the drug develops. To conclude that marijuana users consume the drug to get "stoned" would be as accurate as asserting that alcohol drinkers drink in order to vomit.

imp:

Most marijuana users regulate their use to achieve specific effects. The main technique for regulating the effects of marijuana is manipulating tolerance. Some people who like to get "stoned" on pot, which (unlike the initial side effects of other drugs) can be enjoyable. These people smoke only occasionally. People who like to get "high" tend to smoke more often, and maintain modest tolerance to the depressant effects. But this is not an indefinite continuum. Just as joggers encounter limits, regular users of marijuana eventually confront the wall of receptor down-regulation. Smoking more pot doesn't increase the effects of the drug; it diminishes them.

cool article. it's a pithy way to explain everything i've tried to explain about herb. Plus you know the author is unbiased, because such a well-written article couldn't have been written by a stoner, right?
