In a study published this week, researchers asked tens of thousands of individuals over 12 years of age about their use of tobacco products, e-cigarettes, and their health, and conducted follow-up questions over three years.1 They found the development of lung problems like emphysema, bronchitis, asthma, and chronic obstructive pulmonary disease in individuals who had used e-cigarettes in the past or currently use them. Combined use of e-cigarette and tobacco products dramatically increased lung disease risks by an incredible 330 percent. The researchers concluded that, “Use of e-cigarettes is an independent risk factor for respiratory disease in addition to combustible tobacco smoking.” The study’s senior author, Stanton Glantz, told CNN, "I was a little surprised that we could find evidence on incident lung disease in the longitudinal study, because three years is a while but most studies that look at the development of lung disease go over 10 to 20 years.”
The Centers for Disease Control (CDC) reports that, as of December 10, 2019, there are 2,409 hospitalization cases of vaping-related lung injuries in the U.S., resulting in 52 deaths across 26 states and Washington, D.C.2 The FDA has found THC in most of the samples it’s studying from these cases and has highlighted Vitamin E acetate as a chemical linked to some of the lung injuries. But the CDC warns that it still does not know how many other chemicals and products may be involved, and says that, “the best way for people to ensure that they are not at risk while the investigation continues is to consider refraining from the use of all e-cigarette, or vaping, products.” NIDA just reported that 3.5 percent of 12th graders and 3 percent of 10th graders say they vape on a daily basis, with 14 percent of 12th graders also saying that they vaped marijuana in the previous month. That figure is twice as large as it was last year.
Though federal officials have reportedly backed away from banning flavored vaping products3, some states have implemented such restrictions. And other national lawmakers are still considering similar options to confront the vaping epidemic.4 Dr. Scott Gottlieb, the former FDA Commissioner, has now recommended banning all cartridge-based e-cigarette products, which would include popular devices like Juul.5 Gottlieb, along with other experts, is worried about the epidemic of youth vaping, nicotine use and dependence which can lead to the use of tobacco-based products, the number one cause of preventable death, and other substances later in life.
Stories about vaping-related severe lung diseases, the epidemic of youth use, and public policy responses are important for patients, families, medical professionals, and consumers to follow. But we should also continue to monitor research that paints an even more distressing picture of e-cigarette products. In a recent study, researchers looked at the association between e-cigarette use and cancer.
