DPH Commissioner Renée D. Coleman-Mitchell said, “Over 150 products containing THC have been reported by the patients who have been treated for these lung injuries.”

THC is the psychoactive ingredient in cannabis.

“I am recommending that Connecticut residents consider refraining their use of e-cigarette or vaping products with THC until a definitive source for these serious injuries are identified,” Coleman-Mitchell added.

DPH says they are working with the Center for Disease Control, FDA and other states to determine the causes of the lung injuries.

Earlier this fall, the CDC identified vitamin E acetate as a key-culprit of e-cigarette and vaping lung injuries. Many other substances are currently under investigation, according to DPH.

As of December 10, 2019, there have been 2,049 people hospitalized for lung-injuries connected to vape use in all 50 states, Washington D.C., Puerto Rico and the US Virgin Islands, according to the CDC.

52 deaths have been confirmed in 26 states, including one in Connecticut.
