4、ns of cigarettes to a research company in North Carolina, it was a turning point in the governments war on smoking. These were no ordinary cigarettes, but experimental ones, made of genetically altered tobacco to lower the nicotine content by 97 percent while preserving all the other tastes and smel

5、ls and rituals for smokers of conventional cigarettes. Researchers had been seeking a new and bigger supply because shortages had limited previous studies to just dozens of people. The experimental cigarettes are produced by a Massachusetts company, the 22nd Century Group, which holds 98 patents for

6、 genetic manipulation of tobacco plants to reduce or increase the amount of nicotine in cigarettes. The National Institutes of Health(NIH)bought nine million of these cigarettes, marked “for research purposes only,“ from the 22nd Century Group as part of a broadening scientific effort to find ways t

7、o regulate cigarettes so that they are nonaddictive. The Spectrum brand test cigarettes have eight different levels of nicotine for research, from a nicotine content of 3 percent to 100 percent of the nicotine in the best-selling Marlboro Gold, though a 97 percent reduction is the most common level.

8、 Dr. Nora D. Volkow, director of the National Institute on Drug Abuse of the NIH, which oversees the work, called the delivery crucial for the new federal research projects. These include last months award of $2.5 million for the first year of a planned five-year series of studies into threshold(门槛

9、)levels of nicotine addiction and the possible impact of a sharp reduction in nicotine on smoking and public health. One study of the test cigarettes will follow about 500 smokers over six months to determine whether they are more likely to quit if they switch to those cigarettes quickly or graduall

10、y. The research, led by Dorothy K. Hatsukami, a professor of psychiatry at the University of Minnesota, and Eric C. Donny, associate professor of psychology at the University of Pittsburgh, will use about 1.5 million of the recently acquired cigarettes. For researchers, the availability of a new sup

11、ply of test cigarettes is “a game changer,“ said Mitch Zeller, co-chairman of the Tobacco Harm Reduction Network at the National Cancer Institute and a consultant on nicotine replacement products. “Its still all about the nicotine. Only now we have the power to do something about it. “ At the same t

12、ime, officials in the $80 billion tobacco industry have warned of unexpected side effects from addiction withdrawal and black market products, complex issues the Food and Drug Administration(FDA)will have to study in considering regulation. Under a 2009 law giving the FDA authority over tobacco prod

13、ucts, the agency cannot ban nicotine, but can require that it be reduced to extremely low levels if that is proved to benefit public health. “We really need to have good science to determine whether this might be a product standard, and to have good science, we need reduced-nicotine cigarettes,“ sai

14、d Dr. Hatsukami, who is also a member of the FDA Tobacco Products Scientific Advisory Committee. Her work stalled when companies stopped making very-low-nicotine cigarettes. “In the middle of a study, we dont have the cigarettes,“ she said. “No one has ever sought FDA approval of a cigarette as a me

15、dical device,“ Joseph Pandolfino, the founder and chief executive of 22nd Century, said in an interview. Preliminary studies show smokers can have an easier time quitting if they cut down on the nicotine while still being able to do all the other things they do with cigarettes, he said, but larger s

16、tudies are needed. The growing industry of quit-smoking products has not further dented(削减 )the rather steady rate of smoking recently in the United States, which has stayed at about 20 percent since 2004 after years of notable decline. A new crop of electronic cigarettes and smokeless tobacco produ

17、cts seem aimed more at getting smokers through smoke-free times rather than quitting. Earlier this month, the FDA and NIH also announced they were starting a $ 118 million study to track about 44 000 people over five years to assess usage trends, risk perception, quit-smoking attempts and the possib

18、le impact of new tobacco regulations. In 2006, a federal judge found that tobacco companies had designed cigarettes to precisely control the amount of nicotine and provide doses sufficient for addiction, while concealing much of their nicotine research. They marketed so-called light cigarettes, whic

19、h delivered a lower dose to smoking machines because of holes in the filter, but the same dose or worse to smokers who compensated by covering the holes with their lips and drawing harder. In two small studies by Dr. Hatsukami and Dr. Benowitz, the genetically altered cigarettes were found to defeat

20、 the phenomenon of smoker “compensation.“ But researchers said they needed much more evidence. Tests so far on the experimental cigarettes are encouraging enough that Dr. Hatsukami is going into a Phase 3 clinical trial. That means Phase 2 trials have proven effectiveness on humans. Phase 3 measures

21、 both effectiveness and safety. 22nd Century is also planning to start Phase 3 trials next year. The studies are examining gradual or rapid reductions of nicotine. In a regulated marketplace, the government could set limits on nicotine and ratchet down(逐步减少 ). And teenagers could still experiment wi

22、th cigarettes, as they are wont to do, without getting addicted. “Its a hot topic,“ said Clifford E. Douglas, director of the University of Michigan Tobacco Research Network. “But as difficult as menthol(薄荷醇 )has been, nicotine will be more difficult, because its not 15 million smokers, its every sm

23、oker in the United States.“ The FDAs advisory panel has not put nicotine pn its agenda yet, which is why Dr. Gregory N. Connolly, a Harvard professor of public health and antismoking advocate, said he resigned from the FDA panel in December. “After 50 years of knowing cigarettes cause cancer, its ni

24、ce to know we have a supply we can investigate,“ Dr. Connolly said. “But the real issue is the FDA should have begun a process two years ago to see if we can eliminate nicotine in cigarettes, at least for children. If we can put a man on the moon, we can get rid of nicotine. “ 2 The experimental cig
