Many Vaping Illnesses Linked To Black Market 'Dank Vapes' Or Other THC Products

The mystery of the outbreak of vaping-related lung illnesses is still not solved.

But investigators in Illinois and Wisconsin have found some clues, they announced Friday in a press briefing.

Investigators in these two states conducted detailed interviews with 86 patients — mostly young men — and 66% said they had vaped THC products labeled as Dank Vapes. THC is the psychoactive ingredient in cannabis.

What are Dank Vapes and how could they be fueling the outbreak?

"Dank Vapes appears to be the most prominent in a class of largely counterfeit brands, with common packaging that is easily available online and that is used by distributors to market THC-containing cartridges," said a report from state investigators published Friday by the Centers for Disease Control and Prevention.
