FDA Blunders Again, Endorsing Reduced Nicotine Cigarettes Today…and 27 Years Ago

 

The Well News on January 25 published my commentary on the FDA’s recent regulatory blunder of approving a cigarette that provides all of the smoke but almost none of the nicotine of a traditional cigarette. 

Upon its publication, I received a number of critical emails suggesting that I had failed to properly research the issue.  In fact, those critics failed to do their due diligence on me.  To help them, here is another analysis I published on the subject – back in 1995.

A group of tobacco reformers, led by the Food and Drug Administration Commissioner, has a new regulatory strategy: reduce the amount of nicotine in cigarettes. The theory is that the nicotine concentration of cigarettes will be too low to allow nicotine addiction to be established in new smokers. In the meantime the strategy is intended to serve as a (mandatory) national withdrawal program for the nation’s current smokers.

 

The FDA commissioner has collaborators in this regulatory quest at the highest levels of academia and government. Two well known experts on nicotine addiction, Dr. Neal Benowitz from the University of California at San Francisco and Dr. Jack Henningfield from the National Institute on Drug Abuse, wrote an editorial in the New England Journal of Medicine essentially endorsing the fadeout plan. Although they admitted that “a threshold for nicotine addiction is a theoretical concept ...,” these researchers still postulated a safe concentration of nicotine in cigarettes that would prevent addiction in new smokers. To reach this level, the FDA would have to order a reduction in nicotine content from about eight milligrams per cigarette to about one-half of a milligram, representing a 94 percent reduction.

 

Although the fadeout idea has not been tested with regard to prevention, the plan has been studied for many years as a smoking cessation option. It is basically a drawn-out variation of a strategy called nicotine fading, in which the smoker’s exposure to nicotine is gradually reduced to very low levels. The concept was first introduced in 1979, and numerous trials, usually combining nicotine fading with other behavioral modifications, were conducted throughout the 1980’s.

 

In a recent review of 21 different quit-smoking strategies, nicotine fading came in with an unsurprising success rate — about 25 percent. Dr. Michael C. Fiore, director of the Center for Tobacco Research and Intervention at the University of Wisconsin, questioned the effectiveness of this strategy in helping current smokers quit. Of course if the FDA has its way, this program will not be optional. In other words, a large percentage of current smokers may not find this forced nicotine withdrawal a pleasant experience. What will they do?

 

As they did with low tar low nicotine cigarettes and those with filters, smokers will initially respond to the nicotine phase-out plan by smoking more often and more intensely. Benowitz and Henningfield acknowledged this problem in their editorial. They responded by saying that these smokers’ “short-term (ten-year) risk may be offset by the long-term benefit of a greater likelihood that they will quit smoking (as cigarettes become less satisfying) and by the enormous benefit of preventing nicotine addiction in future generations.”  In other words, they are sorry if your risks increase for ten years because you can't quit, but maybe you'll quit anyway and besides, maybe your children won't get hooked.

 

Another drawback to the fadeout plan is its potential to spawn another huge illicit drug problem. The FDA commissioner commented that “even if we don’t ban cigarettes, we could create a black market by removing the nicotine too quickly.” He seems to believe that the problem is avoidable simply by reducing the nicotine slowly. He is undaunted: “We need to withdraw it at just the right pace, letting the addiction fade as we reduce the nicotine.”

 

There are other fundamental problems with the strategy. For example, setting a threshold level of nicotine exposure below which it is not addictive is an extremely speculative tactic. This would imply that there may be a “safe” level of consumption for all addictions including alcohol, cocaine, and heroin.  A caffeine comparison serves us well here. Utilizing the same rationale concerning effect on body function (addictive potential) and intent (ability to manipulate levels), the FDA has ruled that caffeine is a food additive at concentrations up to 0.02 percent. This amounts to 72 milligrams of caffeine in a twelve-ounce soda. The FDA designates over-the-counter products containing caffeine (up to 200 milligrams per dose) as stimulants. Consistency is not a strong feature of the FDA’s caffeine policy, because a twelve-ounce serving of coffee can have as much as 400 milligrams of caffeine.

 

The important lesson from the caffeine analysis is that the FDA can draw on a precedent for every aspect of the nicotine fading strategy. The plan seems to be bolstered by an elegant scientific rationale, and it superficially appears to be a new and creative approach to the problem of nicotine addiction. However, that's where the real problem lies. Because antitobacco groups have passed judgement on nicotine addiction, they have focused all of their energy on eradicating tobacco. The nicotine fade is simply a thinly veiled disguise for tobacco prohibition.

 

That was my view, published 27 years ago in my clearly timeless book, For Smokers Only: How Smokeless Tobacco Can Save Your Life. Dr. David Kessler was FDA Commissioner at the time.

At the FDA, despite dramatic advances in tobacco science, virtually nothing has changed.

Who Said Light Cigarettes Are Safer? The American Cancer Society


On June 22, Congressman Henry Waxman wrote a commentary (here) in The Hill’s Congress Blog celebrating the first anniversary of his legislation giving the FDA regulatory authority over tobacco. He noted, “Today new regulations take effect banning the use of the terms ‘light,’ ‘mild,’ and ‘low-tar,’ from tobacco advertising, labeling, and marketing. These terms were designed by the industry to mislead consumers, who often think - incorrectly - that products that carry these labels are less dangerous than other tobacco products.”

This line – that safer cigarettes are a deception perpetrated by the tobacco industry -- has been repeated so many times that it is considered gospel by the American public. In fact, the medical and scientific literature makes this a prime example of historical revisionism, if not pure myth.

Research published in the 1970s documented that low-tar low-nicotine cigarettes were less hazardous than others. Contrary to Mr. Waxman’s assertion that “these terms were designed by the industry to mislead consumers,” articles in respected medical journals reveal that the American Cancer Society played a prominent role in shaping consumers’ positive perception of these products.

As I have previously blogged, in 1976 the Cancer Society published research (here) showing that light cigarettes were indeed safer. In 1959-60, over a million people were enrolled by the Cancer Society in a prospective epidemiological study of cancer risk factors. Smokers were classified according to nicotine-tar content, high (2.0-2.7 milligrams nicotine and 26-36 mg tar) or low (less than 1.2 mg nicotine and less than 18 mg tar); detailed records were obtained about the number and dates of deaths.

The study revealed that the death rate from all causes was 16% lower among smokers of low nicotine-tar cigarettes than among smokers of high nicotine-tar cigarettes. Similarly, low nicotine-tar smokers had a 14% lower death rate from heart attacks and a 26% lower rate from lung cancer. The Cancer Society authors concluded that “total death rates, death rates from coronary heart disease, and death rates from lung cancer were somewhat lower for those who smoked ‘low’ tar-nicotine cigarettes than for those who smoked ‘high’ tar-nicotine cigarettes.”

This study was extensively reported on by the media.

In 1979, Cancer Society investigators published a study in the New England Journal of Medicine, confirming the 1976 lung cancer findings (abstract here). This study examined the lungs of 211 men who died in 1955-60 and 234 men who died in 1970-77. It looked for microscopic changes indicating that a cancerous tumor might have eventually developed if these men had lived longer.





















Smoking Category% Pre-cancer, 1955-60% Pre-cancer, 1970-77
NonSmoker 00
Less than 1 pack per day 2.60.1
1-2 packs per day 13.20.8
2+ packs per day 22.52.2



The results from this study are shocking. In 1955-60, when filter or light cigarettes were rare, 2.6% of men who smoked less than a pack per day had pre-cancerous changes in their lungs. Among men smoking 1-2 packs, 13 percent had changes, and this increased to 23 percent among those smoking over 2 packs per day. But in 1970-77, when, according to the report, “a large proportion of smokers have deliberately selected brands with reduced tar and nicotine,” the percentage of smokers in every category who had pre-cancerous lung changes was very small.

Cancer Society researchers concluded: “The evidence from this study is consistent with evidence from epidemiologic studies indicating that death rates from lung cancer are lower among men who smoke the same number of high tar/nicotine cigarettes per day…”

This study appeared in the New England Journal of Medicine, one of the most prestigious medical publications. The results were widely reported by the national media, including the Wall Street Journal.

According to one article (here), ACS president LaSalle D. Leffall Jr. issued a harm reduction message, saying that “findings of the new study suggest a way for smokers to reduce their lung cancer risk by switching to low tar-nicotine cigarettes if they find it impossible to quit entirely.” To his credit, Leffall also noted that “the best way to escape the risk of lung cancer ‘is not to smoke at all…There is no safe cigarette.’”

American smokers made a large-scale transition from full-flavor to light cigarettes almost 50 years ago; the public health impact remains a highly debated topic even today. One fact is not debatable: The marketing of light cigarettes was not entirely an industry-driven conspiracy. The health advantages of light cigarettes compared with full-flavor brands were documented and promoted by the American Cancer Society in 1976 and 1979.
