Yale study: regular e-cigarettes and marijuana products are not associated with electronic aerosol lung disease


A new study by Yale University School of public health found that e-cigarettes and marijuana use rates are high in all States of the United States, but they do not cause more electronic atomization lung disease (evali), foreign media reported.

The study, published in the journal Addiction, examined the relationship between the total number of evali cases per capita reported by States as of January 2020 and adult smoking and marijuana use rates before the outbreak. The results showed that higher smoking and marijuana use rates were associated with a lower number of assessed cases per capita.

"If the use of e-cigarettes or marijuana is itself responsible for the outbreak, then the regions involved in these behaviors should show a higher prevalence of evali," said Abigail Friedman, the study's author and assistant professor The study found the opposite. In addition to the geographical clusters of evali high prevalence States, these findings are more in line with locally available cooking oil or additives than with a product widely used nationwide. "

More than 2800 cases and 68 deaths have been confirmed since the Centers for Disease Control and prevention began a cross state investigation of e-cigarette related lung injuries in August 2019. The center for Disease Control and Prevention (CDC) finished the national update in February 2020, and officially classified vitamin E acetate. The additive has long-term contact with evali and is the most common thc electronic liquid from informal sources, that is, purchased from the street or mixed with families.

The outbreak of evali prompted state and federal legislation to restrict the sale of nicotine e-cigarettes, including a temporary ban on all e-cigarettes in Massachusetts by the end of 2019, and a ban on the sale of flavored e-cigarettes in several States and places. However, if the goal is to reduce the risk of evali, studies have shown that these policies may have targeted the wrong behavior.

There is a negative correlation between the prevalence of evali and the use of e-cigarettes and cannabis before the outbreak, suggesting that mature markets may have squeezed out the use of more risky, informal sources of electronic liquids, Friedman said.

Indeed, of the five states that legalized recreational marijuana, the first five (Alaska, California, Colorado, Oregon and Washington) had less than one evali case per 100000 residents aged 12 to 64. North Dakota, Minnesota, Delaware and Indiana - recreational marijuana is allowed.

Interestingly, Friedman points out that the medical marijuana laws of the two states with the highest prevalence rate prohibit the use of marijuana. " If the policy leads some casual marijuana smokers to switch to THC, perhaps to avoid detection, their exposure to contaminated electronic liquids will increase when these liquids are on the market. This may be the reason for the high prevalence of evali in these states. "

It is important for policy makers to consider the unintended consequences of a policy that bans marijuana and allows thc-e-liquids to move forward.
