CDC Backs Off Nicotine Vaping, Vitamin E to Blame

CDC Vitamin E Vaping Daily blog

The CDC has dropped the warning against vaping nicotine products from its website. The agency made the change this week, as the reported cases of e-cigarette or vaping associated lung injuries (EVALI) slows, and the evidence points to THC-cartridges laced with Vitamin E acetate as the leading cause behind the rash of illnesses and deaths last year.

The CDC’s New Focus

The CDC amended its warning from the blanket recommendation against vaping nicotine e-cigarettes that it made last September, as the outbreak reached its peak. The agency still warns that young people, pregnant women and the elderly refrain from nicotine vaping, while also recommending that people not vape any THC cartridges.

The agency made the change to reflect the evidence uncovered as to the causes behind the outbreak. Data gathered from a majority of hospitalized EVALI patients (2,022, to be exact) showed that:

  • 82% used THC-only vaping products
  • 52% used THC and nicotine vaping products
  • 14% used nicotine-only products

The Evidence Speaks

Vitamin E acetate was suspect from the beginning of the outbreak. There was not enough evidence, in the beginning, to conclusively link the cutting agent to the illnesses, but the more cases that appeared, a pattern started to emerge.

The agency now says that Vitamin E is “strongly linked” to the majority of injured patients. A study done last year found that:

  • 48 out of 51 EVALI patients had detectable levels of Vitamin E in their lung fluid

The CDC also found that a majority of injured patients obtained their THC cartridges from “informal sources,” which the agency classified as “family/friends, dealers, online, or other sources.”

The data released this week showed that:

  • 78% of affected patients bought vaping products only from informal sources
  • 94% of affected patients between the ages of 13-17 bought vaping products from informal sources

These “informal sources” were the target of a crackdown by the FDA’s law enforcement arm, as well as the Drug Enforcement Agency, which seized and shut down 44 suspect sites, last December. The sites were, according to a press release by the FDA, “advertising the sale of illicit vaping cartridges,”. None of the sites, though, were directly linked to tainted THC cartridges.

The End of the Epidemic?

With the main cause identified, the CDC says that new cases of EVALI being reported are declining since its peak in September. The agency credits several factors for the decline, including:

  • Public awareness
  • The removal of Vitamin E acetate as an additive
  • Law enforcement action against suspect suppliers

Even though Vitamin E has been identified as the main culprit, the agency still warns that there could be other, as-of-yet-unidentified chemicals that contributed to the crisis. It still recommends the non-vaping or smoking public not to start either. It also stated that anyone looking to quit smoking should use FDA-approved smoking cessation products, rather than using e-cigarettes.

My way of understanding the significance of vaping came not only through the disruption of smoking but its effects on society as a whole. Now I bring people to vaping and bring vaping to people. I love using new gear, writing in-depth reviews and generally nerding out about vaping to like-minded people.
