SWALLOWING Tortuga Bi LIBERTY writes, "All smoke is bad for your lungs, so cannabis should be eaten, never smoked" (Letters, APRIL 17). This is only partly correct. Yes, all smoke is unhealthful to the lungs and can increase one's chances of cough, bronchitis, and other lung problems, though the data suggest that occasional smokers of marijuana run relatively little risk. And, unlike tobacco, marijuana smoking has not been shown to increase one's risk of lung cancer. Eating marijuana, however, may not be a viable alternative for everyone: Because of how it's processed by the body, cannabis that's eaten tends to act much more slowly, while the psychoactive effect is generally stronger than with smoking and lasts a great deal longer. Depending on circumstances, this may be either good or bad, but it's certainly a different experience than smoking. Another healthy, nonsmoked alternative is vaporization. A vaporizer allows the user to inhale the active components of marijuana, called cannabinoids, without the tars, carbon monoxide, and other toxic combustion products contained in smoke. UC San Francisco researcher Donald Abrams published a landmark study of one such device last year.
