| Description: | Oregon Health & Science University scientists have published the first reliable measurements of "free-base" nicotine in cigarette smoke. Free-base nicotine is believed to be the most available, and thus addictive, chemical form of nicotine in cigarette smoke. Environmental scientist James Pankow, Ph.D., and coworkers found higher-than-expected percentages of free-base nicotine -- as much as 20 times higher in some cigarette brands -- and a wide range of percentages among 11 brands studied. |
