This blog gives my take on how to think about the FDA’s decisions (some taken, some forthcoming) on approving or denying thousands of “pre-market tobacco applications” (PMTAs) to allow vaping products to remain on the US market.  FDA must make decisions no later than 9th September 2021, following legal action brought against the agency. FDA’s Director of the Center for Tobacco Products, Mitchel Zeller, provides the background in a February 2021 blog.
