E-cigarettes less addictive than cigarettes, PATH study shows
People who regularly use electronic cigarettes are less dependent on their product than those who regularly use traditional cigarettes, according to Penn State College of Medicine researchers.
While cigarette use has declined in recent years in the United States, the use of e-cigarettes is increasing, especially among adolescents and young adults. Although the new findings suggest that electronic cigarettes—also known as e-cigarettes—cause less nicotine dependence than traditional cigarettes, planned follow-up studies will help determine if e-cigarettes could lead to use of traditional cigarette dependence down the line.
E-cigarettes include a range of battery-powered devices that heat and vaporize a liquid mixture (e-liquid) that may contain nicotine, flavorings and other chemicals. The vaporized e-liquid is then inhaled as an aerosol. Although the use of e-cigarettes (called vaping) is believed by many experts to be less toxic than cigarette smoking—and could even help some people quit smoking—recent research at Penn State College of Medicine and other institutions indicates that inhaled aerosols produced by vaporizing e-liquids are not harmless.
In addition, experts have raised concerns that e-cigarette use could cause nicotine dependence and lead to cigarette use, reversing hard-won public health gains.
A 2016 report by the Surgeon General called for more research on the use and health impact of e-cigarettes. To that end, health experts and government regulators have been awaiting the first results of the Population Assessment of Tobacco and Health (PATH) study, a comprehensive, ongoing national survey of tobacco use among more than 30,000 young people and adults.
To compare e-cigarette and cigarette dependence, researchers at Penn State College of Medicine analyzed responses to surveys taken in the PATH study. In these responses, they looked for daily or almost daily users of either e-cigarettes or cigarettes.
Out of 32,320 who answered the survey, 3,586 fit the study criteria. Among those, about 5 percent exclusively used e-cigarettes and about 95 percent exclusively smoked cigarettes. Of the e-cigarette users, 93 percent once regularly smoked cigarettes and about 7 percent experimented with cigarette smoking.
Compared with cigarette smokers, e-cigarette users waited longer to start using their product after waking up. Vapers were less likely to consider themselves addicted, to have strong cravings or to feel like they really needed their product. They were also less likely to say they found it difficult to refrain from using their product in restricted places. Researchers report their findings in Preventive Medicine.
All of the participants included in the analysis were considered dependent due to their regularity of use. But the study’s lead author, Guodong Liu, assistant professor of public health sciences, said the findings indicated that e-cigarette users were relatively less dependent than cigarette users.
“No doubt about it, e-cigarettes are addictive, but not at the same level as traditional cigarettes,” Liu said.
Follow-up studies will focus on further analysis of e-cigarette users’ dependency and evolution of e-cigarette use. Around 80 percent of adult PATH participants also submitted blood and urine samples when they were surveyed. Liu’s group plans to study this data when the National Institute on Drug Abuse makes it available to see if participants’ nicotine levels agree with their self-reported dependence.
The researchers also plan to analyze dual users of both e-cigarettes and cigarettes—to draw a more complete picture of nicotine dependence on the entire spectrum of e-cigarette use.
“We suspect that most e-cigarette users are either experimental users or dual users of e-cigarettes and at least one type of traditional tobacco product, like cigarettes,” Liu said. “We want to learn if dual users’ dependence levels differ from each other and also from exclusive e-cigarette or cigarette users.”
Perhaps most critically, the same PATH participants will be surveyed on an ongoing basis, and the results of future waves of data will show if experimental e-cigarette users eventually are converted to regular cigarette users.
