Latest EVALI update

This article brings you the latest CDC update on cannabinoids and e-cigarette or vaping product use-associated lung injury (EVALI), and we discuss the following:

Background

EVALI (e-cigarette or vaping product use-associated lung injury) has been a public health priority since August 2019, when the CDC declared the situation an emergency. The CDC advised people not to use THC containing e-cigarettes and vaping products, because the CDC pinpointed THC as a suspected reason for EVALI.

Of the EVALI patients, 82% used any THC and 33% used only THC, and 57% used any nicotine and 14% used only nicotine.

Warnings about sources

In addition, the CDC also recommended that people do not get these products from informal sources, such as:

  • friends,
  • family members,
  • on-line sources, and
  • drug dealers.

Warnings about components

Further to these cautions, the CDC also established an association of Vitamin E acetate with EVALI, especially in connection with THC containing products. As such, they issued a statement that people should not add to e-cigarettes or vaping products

  • Vitamin E acetate, and
  • any other product not originally intended for vaping purposes.

EVALI – update on the extent of the epidemic

Since mid-January 2020, doctors in 50 US states and territories reported altogether 2,668 cases of EVALI hospitalizations to the CDC: three quarters were non-Hispanic white, two thirds were men, and the average age was 24 years. Having said that, the typical profile of EVALI victims was young white men.

As the figure shows, the number of reported cases were the highest in September 2019, after which the numbers started to fall. The reason for the decrease is public awareness and related informed behavior of customers.

What is next?

Besides Vitamin E acetate, we know little about what other chemicals and/or components might also attribute to lung damage due to vaping and e-cigarettes. This raises a lot of questions, especially because 14% of EVALI cases used products that had only nicotine and no Vitamin E acetate. (One study actually tested these patients for THC, and some tested negative. Those who tested positive had said they used THC some way other than e-cigarettes or vaping.)

Is it possible that these patients simply forgot to mention these risk factors? Or is it that they were unaware that the products also contained THC and/or Vitamin E acetate? Or maybe the evaluating health care professional failed to accurately record these patients’ records?

Another interesting aspect is that several cases of EVALI had occurred even before this outbreak. In those cases, it was nicotine products associated with e-cigarettes.  As such, the presence of patients who smoked only nicotine products, might reflect this background incidence.

Still, the question arises, why do those patients that vape products that contain only nicotine get EVALI? This is an open question that the CDC is trying to answer.
