Sixty-four people in New York State have now been sickened by vape products, according to new statistics released by the state Department of Health.

As of Thursday, the majority of patients — 18 — were treated in western New York, while a dozen were reported in New York City. Three patients were residents of another state but treated at hospitals in New York and 15 were reported outside of the New York City area.

All of the patients, between the ages of 15 and 46, used at least one cannabis-containing vape product prior to becoming sick.

The new numbers come as state officials probe whether high levels of vitamin E acetate could be linked to the mysterious illness, which has caused shortness of breath, coughing, chest pain, fever, nausea, vomiting and, in some cases, death.

The Centers for Disease Control and Prevention said it’s also investigating some 450 cases of vape-related illnesses across the country.

Last week, New York State Department of Health said it received 34 reports of people who had gotten sick after using at least one cannabis-containing vape product.
