In 2019, CDC (Centre for Disease Control and Prevention), reported 1,479 cases of bizarre lung disease across 48 different states of the USA., and around 33 deaths. These deaths have been linked to vaping, as according to CDC around 78% of the patients who were aware of the substances used before getting ill reported they used products containing THC (tetrahydrocannabinol), the psychoactive ingredient of cannabis. According to some experts, responsible for the disease are chemical substances such as vitamin E oils, used to emulsify THC and CBD in unregulated and illegal products existing on the market. “Consumers are urged to avoid buying vaping products on the street and to refrain from using THC oil or modifying [or] adding any substances to products purchased in stores,” the Food and Drug Administration said in a statement.
