A new study out of the University of California found that vaping THC-O acetate may cause lung injury and spark another e-cigarette or Vaping Use-Associated Lung Injury (EVALI) epidemic.
The previous EVALI outbreak happened in 2019-2020 when low-quality cannabis vapes caused hospitalizations and some deaths likely due to vitamin E acetate contamination.
The researchers said when THC-O is heated, it can create a toxic compound called ketene, which is linked to EVALI. THC-O is one of the latest so-called “alternative cannabinoids,” which are made synthetically from hemp-derived CBD and therefore not strictly illegal.
It’s believed to be much more potent (2-3 times) than regular THC and is made through a chemical process that can create unsafe contaminants.
As a reminder, THC-O has seen very little research and we know almost nothing about its safety. Despite this, THC-O is widely available online from dozens of vendors.
