Millions of smokers have already switched to smokefree tobacco products
Switching from cigarettes to smokefree tobacco products has been occurring in the U.S. and in Sweden for many decades, and isn’t an unproven theory (as some harm reduction denialists claim).
The 1986 nationwide Adult Use of Tobacco Survey (AUTS), conducted by the CDC Office on Smoking and Health, found that 7% (i.e., 1.67 million) of male ex-smokers indicated they had used smokeless tobacco (ST) products to help them quit smoking cigarettes, and 6.4% (i.e., 1.63 million) of males who currently smoked indicated using ST to help them quit smoking. In comparison, just 1.7% of male ex-smokers (i.e., 404,600) and 2.4% of males who currently smoked (i.e., 609,000) indicated using organized programs to help them quit smoking cigarettes.

A 1984 Philip Morris market research survey of 489 adult male ST product users in Houston, Atlanta, and Florida (who were interviewed outside retail stores after purchasing ST) found that 37% of ST users stated they were former cigarette smokers (including 22% of those under age 35 and 50% of those 35 years or older). The survey also found that, in response to the question, “Did you start using smokeless/chewing tobacco as a replacement for cigarettes, that is, when you stopped smoking cigarettes, or not?” 20% of ST users said YES (including 11% of those under age 35 and 27% of those 35 years or older). These findings were consistent in the three different survey locations. Interestingly, 62% of respondents who used both ST and cigarettes reported that ST was “more enjoyable” than cigarettes.

The 1991 NHIS found that 33.3% (i.e., 1.75 million) of U.S. adult ST users reported being former cigarette smokers, and the 1998 NHIS found that 31.1% of ST users reported being former cigarette smokers. The 1998 NHIS found that 5.8% of daily snuff users reported quitting smoking cigarettes within the past year, that daily snuff users were 3.2 times more likely to report being former cigarette smokers than were never snuff users who had smoked, and that daily snuff users were 4.2 times more likely to have quit smoking in the past year than were never snuff users who had smoked.

The 1987 NHIS found that, among 23-to-34 year old U.S. males, those who had smoked cigarettes and then subsequently used snuff were 2.1 times more likely to have quit smoking than were cigarette-only users.

A study of 51 female and 59 male SLT users (in the Northwestern U.S.), in which 98% of females and 90% of males were either current or former cigarette smokers, found that 52% of females and 59% of males responded affirmatively when asked whether they used ST in place of cigarettes while quitting smoking.

Another study found that 72% of an estimated 359,000 U.S. smokers who switched to ST products on their last smoking cessation attempt successfully quit smoking.

In Sweden, moist oral snuff is called snus. Unlike moist oral snuff commonly used in the U.S., snus is pasteurized, not fermented, and stored in refrigerators from the time of manufacture until sold at retail. Also in contrast to most ST products commonly sold in the U.S. (except for dissolvable ST products), snus is spitfree, contains fewer nitrosamines, and has not been found to be associated with mouth cancer.

When a large national sample of Swedish ex-smokers was asked about how they succeeded in quitting, 50% stated that they had stopped without help, 33% said they used snuff, and 17% said they had used some form of NRT.

Another survey of more than 6,700 Swedes found that more than 25% of male cigarette smokers indicated they had switched to snus. The survey also found that snus was more effective than NRT products as a smoking cessation aid.

Largely due to smokers switching to snus, the male cigarette smoking rate in Sweden dropped from 40% in 1976 to just 15% in 2002, while snus use among Swedish men increased from 10% to 23%. Due to this decline in smoking, male lung cancer rates in Sweden are the lowest in Europe, while Sweden’s oral cancer rate has fallen during the last 20 years as snus use sharply increased.

An international panel of seven experts, using the Delphi approach, estimated that an additional 10% of cigarette smokers would quit over five years if all smokefree tobacco products in the U.S. were required to be low-nitrosamine products and if those products were accompanied by a warning label that stated: “This product is addictive and may increase your risk of disease. This product is substantially less harmful than cigarettes, but abstaining from tobacco use altogether is the safest course of action.”

Authors of a recent survey of Norwegian men who were either former or current smokers reported: “In a regression model in which education, number of previous attempts to quit smoking, perception of risk, and age were controlled for, the odds ratio (OR) for reporting total abstinence at the time of the survey was significantly higher for those who had used varenicline (OR = 4.95, p < .006) and snus (OR = 2.68, p < .001) compared with those who had used nicotine chewing gum (reference OR = 1).” and “Compared with medicinal nicotine products, snus and varenicline increased the probability of quitting smoking completely”.
