</p>
<p>
As of November 20, 2019:</p>
<p>
2290 cases of e-cigarette, or vaping, product use-associated lung injury (EVALI) from 49 states (except Alaska), District of Columbia and 2 U.S. territories.</p>
<ul>
<li>
Largest number of cases (150-199) reported from CA, TX and IL</li>
<li>
47 deaths</li>
</ul>
<p>
Analysis of 29 bronchoalveolar lavage (BAL) fluid samples from EVALI patients submitted to CDC from 10 states showed:</p>
<ul>
<li>
Vitamin E acetate in all samples </li>
<li>
THC: 82%</li>
<li>
Nicotine: 62%</li>
<li>
No other chemicals of concern were identified (e.g. plant oil, mineral oil, terpenes, etc.) </li>
</ul>
<p>
*** Vitamin E acetate appears to be associated with EVALI but the investigation is continuing.*** </p>
<ul>
<li>
Oral ingestion of vitamin E acetate does not cause harm.</li>
<li>
High dose vitamin E supplementation (>2000 IU/day [2000 mg/day]) can cause GI symptoms: nausea, vomiting, diarrhea and abdominal pain.</li>
</ul>
<p>
Some research has suggested that oral vitamin E use has potential beneficial effects (i.e. anti-inflammatory/antioxidant) in the lung (e.g. asthma and allergic lung disease), cardiovascular disease and prostate cancer (Cook-Mills JM et al. 2013; Jiang Q et al. 2001)</p>
<p>
Common uses of vitamin E</p>
<ul>
<li>
Topical cosmetic skin products (skin cream) for antioxidant effect.</li>
<li>
Essential dietary vitamin (fat soluble) found in many food items and as dietary supplement.</li>
<li>
In vaping products: vitamin E is used as an additive/thickening agent in THC containing e-cigarette, or vaping products.</li>
</ul>
<p>
There is limited to no data on pulmonary effect of vitamin E from inhalation in the scientific literature.</p>
<p>
Stay tuned for additional updates from CDC.</p>
