Legislative momentum continues to build for action against vaping in the wake of highly publicized deaths and illnesses vaguely attributed to the industry. Desperate to appear responsive to a purported public-health crisis, states including New York, Michigan, Washington, Massachusetts, Oregon, Rhode Island, Ohio, and California are moving to ban sales of certain e-cigarette products or have done so already. The legislative target has already moved subtly from black-market cannabis poisoning — the most likely culprit for these deaths — to the unrelated and heavily hyped “youth flavor-vaping epidemic.” Some cities have already banned flavored e-cigarettes.
