The Centers for Disease Control and Prevention have backed away from its broad recommendation that anyone who uses e-cigarettes of any kind should consider quitting amid an outbreak of vaping-related illnesses and deaths. Instead, it is only recommending avoiding vaping products containing THC, the high-inducing chemical in marijuana, a narrower warning.

A warning that “the best way for people to ensure that they are not at risk while the investigation continues is to consider refraining from the use of all e-cigarette, or vaping, products” was gone from the CDC website as of Friday. The CDC still warns that young people and pregnant women should not vape and that nonsmokers should not start vaping.
