Vaping is no longer a passing fad among teenagers, and has turned into a national epidemic, said experts contacted by MedPage Today.
A
growing body of literature confirms these fears. Most recently, the large Monitoring the Future survey in 2018 found "the largest single-year increase in use of a monitored substance ever recorded" among high school students in the program's four-decade history.
McGrath-Morrow said tobacco-naive kids who try e-cigarettes will not experience the initial adverse effect in the throat that is felt with tobacco smoking, which makes it much more likely they will continue use and become addicted to the nicotine often packaged in small pods that can contain as much nicotine as up to 20 cigarettes.
"I think this is our opportunity to not let what happened with tobacco products happen, but we only have a small window of opportunity to really push," McGrath-Morrow told MedPage Today. "Even if we don't have all the information, it's pointing in the direction that kids are highly addicted to nicotine and that this could be a gateway to tobacco use, and we know how bad tobacco use is."
But research that determines long-term cardiovascular, respiratory, or neurological effects of nicotine use in adolescents has not been conducted. And this research is likely what will motivate more restrictive guidelines, dispel the notion that e-cigarettes are healthy or benign, and discourage youth from vaping, said Michael Weaver, MD, of McGovern Medical School at UTHealth in Houston.
The problem is that research that could observe these longitudinal changes in adolescent health might take up to a decade to complete, Weaver said.
"We've got at least another 5-10 years before we have good, long-term data on the effects of e-cigarettes on the lungs, the heart, the brain, or something else we hadn't considered, so unless something new emerges early and unexpectedly, [such as] higher doses of vegetable glycerin causes cancer or allergic reactions or something, we're going to have to wait for more data to accumulate," Weaver told MedPage Today. "I think the trend is going to have to run its course for at least a few more year
