Health officials said Friday that black market cannabis products could be the cause of a mysterious outbreak of severe lung disease among vapers that has sickened more than 200 people and killed two.
New York's health department said laboratory test results showed very high levels of vitamin E oil in cannabis cartridges used by all 34 people in the state who had fallen ill after using e-cigarettes.
"As a result, vitamin E acetate is now a key focus of the Department's investigation of potential causes of vaping-associated pulmonary illnesses," the department said in a statement.
