Diabetics are more likely to suffer from severe cases of COVID-19 than non diabetics. Understanding the origins of COVID-19 is likely to help stop the pandemic. Stating in April of 2019 an epidemic of severe E-Vaping Acute Lung Injury (EVALI) occurred primarily in people vaping the cannabis extract THC and living in the USA. The etiology of this epidemic was never fully explained nor why the epidemic was focused in the USA. A literature review was conducted to compare cases of EVALI to patients with COVID-19. Many of those suffering from EVALI in 2019 had an clinical syndrome indistinguishable from COVID-19. There is a significant possibility that some of patients suffering from EVALI in 2019 were actually infected with COVID-19. Antibody studies to COVID-19 in patients who were stricken by EVALI should be done of further investigate this association.
