Vaping Soars Among US Teens, CDC Report Finds

Use of electronic vapor products, or vaping, more than doubled among US high school students from 2017 to 2019 (from 13.2% in 2017 to 32.7% in 2019), a report from the Centers for Disease Control and Prevention (CDC) has found. Current cigarette smoking decreased from 8.8% to 6% during that time, as did cigar smoking (from 8% to 5.7%) and smokeless tobacco use (from 5.5% to 3.8%).

Current use of any tobacco product increased from 19.5% in 2017 to 36.5% in 2019.

"The dramatic increase in electronic vapor product use among high school students has led to increases in overall tobacco product use among U.S. youths, erasing gains made in previous years and leading the U.S. Surgeon General to declare youth e-cigarette use an epidemic in the United States," the authors write.

"The new youth tobacco use data released today from CDC's 2019 Youth Risk Behavior Survey confirm that our nation is facing multiple public health crises simultaneously: the COVID-19 pandemic, continued racial health equity disparities, and a youth vaping crisis," Harold Wimmer, president and CEO of the American Lung Association, said in a statement about the findings.

"The dramatic increase in youth vaping led to a near doubling of overall tobacco product use among high school students, from 19.5% in 2017 to 36.5% in 2019," he added.

MeLisa R. Creamer, PhD, from the Office on Smoking and Health in the CDC's National Center for Chronic Disease Prevention and Health Promotion, and colleagues report their findings in an article published online August 20 in Morbidity and Mortality Weekly Report.

 

The researchers analyzed data from the 1991 to 2019 cycles of the CDC's biennial national Youth Risk Behavior Survey. The findings, the authors say, are in line with those from other national surveillance systems, including the National Youth Tobacco Survey and Monitoring the Future.

Frequent use (20 or more days during the previous 30 days) of electronic vapor products also increased among current electronic vapor product users (from 25.1% to 32.6%), but frequent cigarette smoking fell, and frequent use of smokeless tobacco or cigars remained the same among users of those products.

The use of two or more tobacco products did not change from 2017 to 2019. "Multiple tobacco product use is associated with substance use disorders and might increase nicotine exposure and risk for nicotine dependence," the authors explain.

Differences by Demographic Group

Among current vapers, the usual source of obtaining these products differed by age. Those aged 17 years or younger most often said they borrowed them from someone else (42.8%). Among those age 18 or older, 56.4% said they purchased them in a store.

Federal legislation raised the minimum age for tobacco product sales from 18 to 21 years nationwide on December 20, 2019.

Students aged 17 years or younger were more likely to get tobacco products on the internet, give someone else money to purchase them, borrow them from someone else, get them from someone who could buy them legally, or get them another way.

Male students were more likely to report that they use cigarettes, cigars, smokeless tobacco, and two or more tobacco products when compared with female students. The prevalence of tobacco product use was higher among those in 12th grade than among those in 9th grade.

White and Hispanic students had a higher prevalence of current use of electronic vapor products, cigarettes, any tobacco product, and at least two tobacco products when compared with Black students. White students were more likely than Hispanic students to say they used electronic vapor products and any tobacco product.

Youth aged 18 years or older were more likely than students aged 16 or 17 and those aged 15 years or younger to say they currently used cigars. Prevalence rose in each age group for all other individual products, any tobacco product, and multiple tobacco products.

Students who were heterosexual, lesbian, gay, or bisexual were more likely than those who were "not sure" about their sexual identity to report using electronic vapor products. Those who were lesbian, gay, or bisexual were more likely than heterosexual students to currently use cigarettes, cigars, and tobacco products, and multiple tobacco products. Any tobacco product use was more common among lesbian, gay, or bisexual students when compared with students unsure of their sexual identity.

Flavored Tobacco Products Driving Much of Increase

Flavored tobacco products, including flavored vaping devices, are responsible for the sharp rise in their use. From 2016 through 2017, sales of JUUL, "the most commonly sold e-cigarette in the United States since December 2017," rose approximately 600% (from 2.2 million unit sales to 16.2 million unit sales), the authors write.

By December 2018, three quarters (76%) of the $322.1 million total e-cigarettes sales during that month in the United States were JUUL products. Several factors likely explain the appeal of these products to youths, including exposure through advertising, the availability of desirable flavors, curiosity, and being around friends and other individuals socially who use the products.

"We need look no further for the cause of this spike than the rise of JUUL and now Puff Flow and Vuse, and the continued sale and proliferation of flavored tobacco products, including flavored vaping devices," Wimmer said.

"The tobacco industry has long used flavored tobacco products as starter products for kids and continues with flavored e-cigarettes today. And these data show that e-cigarette companies, many of which are owned by major tobacco companies, have successfully used Big Tobacco's playbook to hook another generation of America's kids," he continued.

Even infrequent use of tobacco products — in particular, cigarette smoking — is predictive of developing a daily smoking habit, and infrequent use has been associated with nicotine dependence.  

"Flavors are known to lure and hook kids to a lifetime of tobacco addiction, and we see this reflected in the continued spike of the amount of youth vaping," Wimmer explained. "To protect kids, the American Lung Association has long called for menthol cigarettes and all flavored tobacco products, including e-cigarettes, to be removed from the marketplace.

"The Food and Drug Administration (FDA) has a unique opportunity to reverse this spike in youth use, by denying any flavored tobacco product permission to remain on the market when it reviews the applications due to the agency on September 9. In the meantime, our states and communities must act to fill the void left by FDA's failure to take action by passing state and local laws to prohibit the sale of all flavored tobacco products."

Limitations of the study include changes in the wording of questions in 2017 that make it impossible to compare data from previous years and "long-term trend analyses for prevalence of smokeless tobacco use, any tobacco product use, and use of two or more tobacco products," the authors explain.

The question about how students obtained tobacco products only allowed students to select one response, but students may have several sources for obtaining the products and the full scope of their access is unclear.

The findings are part of a larger report on youth risk behavior.

The authors have disclosed no relevant financial relationships.
