Multiple brands could be the cause of vape injuries

December 13 news, according to foreign news reports, according to the latest update from the United States Centers for Disease Control (CDC), THC-containing electronic atomizing products sold under the name Dank Vapes are the most common brands related to atomization-related injuries. However, there are regional differences in brands related to injuries and hospitalization, and officials say a brand is likely not responsible for the outbreak of injuries.

As of December 3, in the United States, 2291 patients had been hospitalized due to electronic nebulization-related injuries and are now known as EVALI (vape or nebulization-related lung injury). Only 1782 of these patients provided information on the products they used, and in this group, 80% of patients reported using THC-containing steam products within three months before the onset of symptoms.

According to the CDC's weekly report on morbidity and mortality, the latest data show that the number of cases reported each week has declined since mid-September.

EVALIA hospitalized patients reported using 152 different types of THC-containing products. 56% of patients providing this information used Dank Vapes products.

Other brands are more common in different parts of the U.S .: For example, it is reported that 24% of inpatients in western states report Smart Cart, compared to only 6% in the northeast. According to reports, in the West, 29% of hospitalized patients use the TKO brand, while in the South, the proportion is only 2%. Other common brands include Rove, Kingpen and Cookies.

CDC's Epidemic Services Officer and author of the new report, Matt Lozier, said that by understanding the THC-containing brands used by EVALI patients, we can prioritize product testing to find the chemicals of interest in these products.

Vitamin E acetate remains the focus of investigation of the cause of injury. Product testing conducted by the US Food and Drug Administration (FDA) found that 76% of tetrahydrocannabinol-containing products provided by EVALI hospitalized patients. Studies have shown that it can cover and damage the inside of the lungs. But not all tetrahydrocannabinol products tested contained vitamin E acetate, and some patients admitted to the hospital still said they did not use any tetrahydrocannabinol products.

For example, according to data also published today in the Weekly Morbidity and Mortality Report, in Indiana, only 69% of patients who were interviewed about the use of their products said they used products containing tetrahydrocannabinol.

However, only 29 of the 54 inpatients in Indiana completed interviews with investigators. The National Centers for Disease Control and Prevention's (CDC) national report states that they do not have information on the products used by many patients, making it difficult to generalize their findings to the entire injured population. People may also be reluctant to disclose whether they use THC products, especially if they live in illegal places or teens.

The CDC told The Verge that they had no data on whether patients were more willing to talk about THC use over time.

The cause of the injury is still under investigation. However, the new data reinforces the CDC's recommendation that people avoid using THC-containing products.
