Mysterious vaping lung injuries may have flown under regulatory radar


 

Regulatory limits

The FDA has had limited authority to regulate e-cigarettes over the years.

In 2009, Congress passed the Family Smoking Prevention and Tobacco Control Act, empowering the FDA to oversee the safety and sale of tobacco products. But e-cigarettes, still new, were not top of mind.

Later that year, the FDA tried to block imports of e-cigarettes, saying the combination drug-device products were unapproved and therefore illegal for sale in the United States. Two vaping companies, Smoking Everywhere and NJoy, sued, and a federal judge ruled in 2010 that the FDA should regulate e-cigarettes as tobacco products.

It took the agency 6 years to finalize what’s become known as the “deeming rule,” in which it formally began regulating e-cigarettes and e-liquids.

By then, it was May 2016, and the e-cigarette market had swelled to an estimated $4.1 billion, Wells Fargo Securities analyst Bonnie Herzog said at the time. Market researchers now project that the global industry could reach $48 billion by 2023.

Critics say the FDA took too long to act.

“I think the fact that FDA has been dillydallying [has made] figuring out what’s going on [with this outbreak] much harder,” said Stanton Glantz, PhD, a University of California, San Francisco, professor in its Center for Tobacco Control Research and Education. “No question.”

The agency began by banning e-cigarette sales to minors and requiring all new vaping products to submit applications for authorization before they could come to market. Companies and retailers with thousands of products already on the market were granted 2 years to submit applications, and the FDA would get an additional year to evaluate the applications. Meanwhile, existing products could still be sold.

But when Scott Gottlieb, MD, arrived as the new FDA commissioner in 2017, the rule hadn’t been implemented and there was no formal guidance for companies to file applications, he said. As a result, he pushed the deadline back to 2022, drawing ire from public health advocates, who called foul over his previous ties to an e-cigarette retailer called Kure.

“I thought e-cigarettes at the time – and I still believe – that they represent an opportunity for currently addicted adult smokers to transition off of combustible tobacco,” he said in an interview, adding that other parts of the deeming rule went into effect as planned. “All I did was delay the application deadline.”

Dr. Gottlieb’s thinking changed the following year, when a national survey showed a sharp rise in teen vaping, which he called an “epidemic.” He announced that the agency would rethink the extended deadline and weigh whether to take flavors that appeal to kids off the market.

A judge ruled last month that e-cigarette makers would have only 10 more months to submit applications to the FDA. They’re now due in May 2020.

Asked about the lung injuries appearing now, Dr. Gottlieb, who left the FDA in April 2019, said he suspected counterfeit pods are to blame, given the geographic clustering of cases and the fact that, overall, the FDA is inspecting registered e-cigarette makers and retailers to make sure they’re complying with existing regulations.

“I think the manufacturers are culpable if their products are being used, whether the liquids are counterfeit or real,” he said. “Ultimately, they’re responsible for keeping their products out of the hands of kids.”

Juul, the leading e-cigarette maker, agreed that children shouldn’t be able to vape its products, and said curtailing access should be done “through significant regulation” and “enforcement.”

“When people say ‘Why aren’t these being regulated?’ They actually are all being regulated,” Dr. Gottlieb said.

For example, companies are required to label their products as potentially addictive, sell only to adults and comply with manufacturing standards. The agency has conducted thousands of inspections of e-cigarette manufacturers and retailers and taken enforcement actions against companies selling e-cigarettes that look like juice boxes, and against a company that was putting the ingredients found in erectile dysfunction drugs into its vape liquid.

Health departments investigating the outbreak told Kaiser Health News that e-cigarettes’ niche as a tobacco product instead of a drug has presented challenges. Most weren’t aware that adverse events could be reported to a database that tracks problems with tobacco products. And, because e-cigarettes never went through the FDA’s “gold-standard” approval process for drugs, doctors can’t readily look up a detailed list of known side effects.

But like other arms of the FDA, the tobacco office has tools and a team to investigate a public health threat just as the teams for drugs and devices do, Dr. Gottlieb said. It may even be better equipped because of its funding.

“I don’t think FDA is operating in any way with hands tied behind its back because of the way that the statute is set up,” he said.

Teen vaping has exploded during this regulatory tussle. In 2011, 1.5% of high school students reported vaping. By 2018, it was 20.8%, according to a CDC report.
