FDA: "Avoid THC Vaping Liquids"

On Friday the US Food and Drug Administration, or FDA, issued a statement advising consumers to avoid all THC containing-vaping liquids. Doctor say that most cases of lung injury linked to vaping have involved products containing THC.

The investigation into what, exactly, is causing lung injury in vaping users is still in its early stage and, of course, is ongoing. But doctors who have studied those cases say that most, but not all, victims of respiratory illnesses linked to vaping appear to have used vaping liquids made with tetrahydrocannabinol, or THC. And most of those also contained what the agency is referring to as "significant amounts" of vitamin E acetate.

No single brand, seller, or manufacturer has been singled out as a potential source.

Right now, say investigators, it isn't clear whether the THC or the vitamin E ingredient is the problem. Perhaps, it is a combination of the two. In any case, users of vaping products are urged not to buy vaping products off the street and not to add any substances, including THC, to their vaping liquids.

And, of course, teenagers shouldn't be vaping at all.
