British and Australian Smokers Attracted to Smoke-Free Substitutes

A study published in Harm Reduction Journal (here) concludes that there is “an untapped interest in the use of substitutes to reduce the harmfulness of smoking…The greater the range of products on offer, the more smokers are likely to try a product to quit.”

The study’s lead author is Ron Borland at Australia’s VicHealth Center for Tobacco Control. His coauthors are from the University of Nottingham in the UK, and Roswell Park Cancer Institute in Buffalo, New York.

Thirty-four smokers in the UK and 31 in Australia were recruited; each received a variety of smoke-free substitutes for “short term use (less than 1 week).” In the UK, 15 smokers preferred nicotine lozenges, 9 preferred Oliver Twist (here), one liked both products and 8 liked neither. Smokers in Australia were sent more products, and 17 tried all of them. Six favored Oliver Twist, 5 liked nicotine lozenges, 2 preferred Swedish snus (here) and one favored Stonewall/Ariva dissolvables (here); three smokers didn’t like any of the smoke-free alternatives.

Borland and colleagues reported that there was “considerable interest in using [pharmaceutical nicotine and smokeless tobacco] as a means of quitting smoking or as a long-term substitute for smoking.” They added that “the greater range of options provided, the more likely we are to find one that will be acceptable to any given smoker, thus increasing the potential pool of those who might be helped” and they advocated sampling to get “the participant to choose the product they wanted to use longer term” as a “sensible and viable approach for encouraging more than minimal use of substitute products.”

The authors reasonably write that smokers should try a variety of smoke-free substitutes, but they add an unrealistic caveat -- “we should not allow for-profit companies to directly market them to consumers, rather they should be available from a not-for-profit source.”

Borland and colleagues conclude that “…many smokers are interested in reducing the harmfulness of their smoking behaviour. Smokers deserve to know what the differential risks of potential alternatives are, and to be supported to make the choices that are in their long-term best interests, which is to quit nicotine altogether, but failing that use the least harmful form of nicotine they find acceptable.”

Many smokers are interested in harm reduction, but too many are dying every year – 15,000 in Australia, 80,000 in the UK and 400,000 in the US – because they don’t have truthful information about vastly safer cigarette alternatives.

Evidence That Dissolvable Tobacco Works for American Smokers

Researchers from the Department of Psychiatry at the Medical University of South Carolina have published a small, but persuasive, study documenting that dissolvable tobacco products “led to a significant reduction (40%) in cigarettes per day, no significant increases in total tobacco use, and significant increases in two measures of readiness to quit, either in the next month or within the next 6 months.”

The study was funded by the National Institute on Drug Abuse, a U.S. government agency, and it was published by Matthew Carpenter and Kevin Gray in the online edition of Nicotine and Tobacco Research.

Carpenter and Gray randomly assigned 31 smokers who were uninterested in quitting to receive Ariva or Stonewall, dissolvable smokeless products from Star Tobacco (that I have recommended to smokers for many years here and here), or to continue smoking cigarettes. Smokers were given “minimal instructions on how to use” these products and were “told that there is no safe tobacco product and that the best thing they can do for their health is to quit entirely.”

Carpenter and Gray wrote that their findings suggest “that Ariva and Stonewall are effective products to curb withdrawal and craving.” In other words, these products satisfy smokers.

Perhaps the researchers’ most important conclusion was that there is “no evidence that smokeless tobacco (Ariva or Stonewall) undermines quitting. To the contrary, readiness to quit (in the next 1 month and within the next 6 months) significantly increased among smokers who used a smokeless tobacco product relative to those who continued to smoke conventional cigarettes.”

This is important because tobacco prohibitionists have complained that telling smokers about vastly safer smokeless substitutes will “undermine quitting.” Never mind that this puts their dream for a tobacco-free society ahead of the health of people who smoke. The new research shows that tobacco harm reduction is completely consistent with both the health of smokers and broader public health goals.

Had Carpenter-Gray successfully completed a lung cancer vaccine trial, it would have made international headlines. Instead, their monumental study on smokeless tobacco, with major implications for immunizing smokers against lung cancer, has gone unnoticed. With the lives of millions of smokers at stake, their work deserves greater attention.
