Number of vaping deaths up to 26, CDC says

The number of deaths related to vaping has jumped from 18 to 26 in the last week, the Centers for Disease Control and Prevention announced.

There were also 219 new cases of illness related to e-cigarettes in the last week, bringing the total number of probable cases to 1,299. The CDC said cases have been found in 49 states, up from 48 last week. They have also been found in Washington, D.C., and the Virgin Islands.

Health officials say they still do not know exactly what is making people sick, although around 76 percent of patients said they had vaped THC and 13 percent said they vaped exclusively nicotine.

The majority of those with the illness are men and 80 percent are under the age of 35, according to the CDC. People who have died ranged from 17- to 75-years-old.

The CDC has urged people to stop vaping, especially THC or products from off the street.
