CDC recommends against using vapes with marijuana ingredient

The Centers for Disease Control and Prevention issued a new warning Friday, urging people to stop using e-cigarettes, especially those with the cannabis-derived ingredient THC.

The warning comes as an investigation into illnesses and deaths related to vaping deepens.

E-cigarettes have been marketed as tools to help smokers quit, but rising use among youth in the United States and a spate of severe lung illnesses tied to the devices have triggered a backlash and heightened regulatory scrutiny.

Health officials are investigating 805 confirmed and probable cases and 12 deaths so far from a mysterious respiratory illness tied to vaping, as of the latest update on Thursday.

Washington state Governor Jay Inslee urged state agencies on Friday to ban flavored and cannabis-derived vaping products, joining other states and the federal government in taking steps to reduce vaping amid the mysterious outbreak of deaths and illness.
