Dear Attorney General Miller:

Thank you for your Jetter to Dr.  Rochelle WaJensky, Director of the Centers
for Disease Control and Prevention (CDC), requesting that the agency rename
"E-cigarette, or Vaping, Product UseAssociated Lung Injury" (EV ALI).  I am
responding on Dr.  WaJensky's behalf.

From August 2019 to Februai·y 2020, CDC, the Food and Drug Administration, state and local
health departments, and other clinical and public health partners investigated a national outbreak
of EV ALI. Case peaked in September 2019, with a substantial decline thereafter. Though it has
been more than a year since the decline in cases and CDC stopped routinely collecting
information from states on EV ALI cases, the agency continues to monitor EV ALI-related trends
using syndromic surveiJlance. These data do not suggest a resurgence of EV ALI.

EV ALI was named in the early tage of the outbreak based on information that
was known, including case patient reports of the use of a wide range of
e-cigarette, or vaping, product .  CDC and others broadly communicated that
the outbreak investigation has shown most cases of EV ALI were linked to
Tetrahydrocannabinol (THC)-containing e-cigarette, or vaping, products,
particularly from informal sources.  Vitamin E acetate, an additive in some
THC-containing ecigarette, or vaping, products, was strongly linked to the
EV ALI outbreak.  However, the evidence remains insufficient to rule out the
contribution of other chemicals of concern, including chemical s in either
THC or non-THC products, in some reported EV ALI cases.  As noted in the
January 24, 2020 Morbidity and Mortality Weekly Report, "Update:
Characteristics of a Nationwide Outbreak of E-cigarette, or Vaping, Product
Use-Associated Lung Injury United States, August 20 19-January 2020," 1 14
percent of EVALI patients reported exclusive use of nicotine-containing
producl .  The identification of EV ALI ca e patients reporting excJ u ive
use of nicotine-containing product i reported elsewhere.  2 · 3 .4

Given the lack of ev idence to rule out the contribution of other chemicals
of concern to the EV AU o utbreak, the pos ibility that chemicaL of concern
co uld be introduced into su pply chains of either THC o r
non-THC-containing product in the future, the prudence of assessing sub
tance use broadly where c linical ly indicated , and that some EV ALI cases
reported exclu 1ve u e of nicotine-containing product , CDC declines to
rename EV ALI.  CDC will continue to monitor EV ALI-related trend , provide
EV ALI-related help to state as needed, and provide nece sary update · to
the public.  5

We appreciate your letter and interest in thi important public health topic. 
Plea e share a copy of this re ponse with the co-sig ners of your letter.
