Vaping illnesses soar past 1,000 with investigators no closer to pinpointing cause

The Food and Drug Administration should have acted sooner to curb the surge in youth vaping, the acting head of the agency, Dr. Ned Sharpless, told a House subcommittee Wednesday in his first appearance before Congress since news of severe lung illnesses linked to vaping began to circulate this summer.

State health departments in nearly every state tell NBC News that they are actively investigating more than 1,000 cases of the illnesses. That’s higher than the Centers for Disease Control and Prevention’s official case count, currently at 530, which only includes confirmed or probable cases.

Eleven people have died: Two in California, two in Kansas, plus deaths in Illinois, Indiana, Minnesota, Missouri and Oregon. Georgia confirmed its first death Wednesday, and Florida confirmed a death on Tuesday.

But despite investigations by hundreds of physicians, state health officials, the FDA and the CDC, no single ingredient or product has been identified as the cause of the illnesses.

The FDA has received 300 vape product samples, and has tested about half for the presence of nicotine, THC (the psychoactive ingredient in marijuana), painkillers, cutting agents, pesticides and toxins.

About half of the products that contained THC also contained an ingredient vitamin E acetate, Sharpless said. That’s an oil that has “no business being in lungs.”

But there’s no evidence that one ingredient can explain all of the lung illnesses. Health investigators say it’s likely there are multiple causes.

“There may be a particular problematic source in California, and something different going on on the East Coast,” said Dr. Anne Schuchat, the CDC’s principal deputy director. Schuchat also testified before the subcommittee Wednesday.

She said the tedious investigation cannot keep up with the fast-moving spate of illnesses.

“The data are coming in as we speak,” Schuchat said. “I’m extremely frustrated with the pace of our investigation.”

Sharpless also told legislators that the FDA is finalizing plans to remove flavored electronic cigarettes from the marketplace, and will begin enforcing the “existing law that limits the marketing of such products” in the coming weeks.

That means flavored e-cigarettes would essentially be banned from being sold, unless companies can provide evidence their products would benefit public health.

Some states have already enacted temporary bans on flavored vapes, including Michigan, New York and Rhode Island. Massachusetts went one step further, banning all vaping devices for four months.
