Prepackaged sachets of nicotine, flavors, artificial sweeteners and other chemicals are becoming increasingly popular as alternatives to cigarettes. While oral nicotine pouches contain fewer carcinogens than cigarettes, a new study from the Center for Tobacco Research at The Ohio State University Comprehensive Cancer Center finds that oral nicotine pouches do not curb nicotine cravings as quickly as cigarettes.
Nicotine pouches, while containing fewer toxins than cigarettes, are unlikely to help smokers quit.
Nicotine sachets that contain no tobacco leaves and are marketed as alternatives to cigarettes are less effective at reducing nicotine cravings in current smokers, a recent study shows. The study was conducted by public health experts at The Ohio State University Comprehensive Cancer Center (Arthur G. James Cancer Hospital) and the Center for Tobacco Research (The Center for Tobacco Research) at the Richard J. Solove Research Institute. The results of the study were published in the medical journal "Addiction" (Addiction).
Nicotine pouches are pre-portioned sachets that contain nicotine powder, flavors, artificial sweeteners and other chemicals to extend shelf life. Since entering the consumer market in 2016, these products have become increasingly popular as a smokeless, tobacco-free alternative to cigarettes.
Lead author Dr. Brittney Keller-Hamilton said these products are attractive to current smokers because they contain fewer known carcinogens and toxins than other tobacco products and can be used indoors where smoking is prohibited. However, researchers worry that if not carefully formulated and regulated, these products may lead to an increase in the use of nicotine products among young people rather than reducing smokers' cancer risk.
In this study, researchers evaluated whether nicotine pouches with different nicotine concentrations were more or less attractive to smokers.
They found that current smokers had a much larger spike in blood nicotine levels while smoking and a greater relief of craving symptoms compared to using low-dose and high-dose nicotine pouches. Keller-Hamilton explained that the peak of measurable nicotine in the blood occurs about five minutes after smoking. With nicotine pouches, the process, like other smokeless tobacco products, is more gradual - typically taking 30 minutes to an hour to reach peak effect - meaning craving symptoms are relieved. The same goes for the drop in nicotine levels - it's also more gradual after oral administration.
Because of this, there's reason to believe that for people already addicted to nicotine, the instant gratification of smoking is more appealing than oral nicotine pouches. "The challenge we face is how to regulate nicotine pouches to limit their appeal to young people while making them more attractive to adult smokers," Keller-Hamilton said.
Research results and methods
For the current study, Keller-Hamilton's team recruited 30 active adult smokers from Appalachian communities in Ohio.
Researchers observed participants three times during which they either smoked their usual brand of cigarettes or used oral pouches containing either three milligrams or six milligrams of nicotine. Researchers took repeated blood samples during product use to measure changing plasma nicotine levels. The researchers also asked participants to fill out a nicotine craving questionnaire before using the product, and again within 5, 15, 30, 60 and 90 minutes after starting to use the product.
"Nicotine addiction is a very real problem for many people, and most current smokers say they want to quit, but often fail because quitting -- and staying quit over the long term -- is just too challenging," Keller-Hamilton said. "For smokers trying to make healthier choices or quit smoking, they should talk to their health care provider or call their state's quit line to find the best quit option for them."
Continuous research provides scientific basis for tobacco regulation
The Ohio State University Tobacco Research Center is conducting ongoing research to inform regulation of oral nicotine pouches through a newly funded $20 million Tobacco Regulatory Science Center grant from the Food and Drug Administration and the National Institutes of Health. This grant will enable scientists to conduct further research to inform oral nicotine pouch regulations and promote public health. This includes studying how various aspects of nicotine affect the appeal, addiction and use of nicotine oral pouches.
Researchers will also study how these factors affect product switching - for example, switching from smokeless tobacco or combustible cigarettes to nicotine snus pouches. Additionally, the study will examine how use of these products affects the microbiome of people who switch from smoking or using smokeless tobacco to using nicotine pouches.
