States that permit recreational marijuana sales tend to have lower rates of vaping-related hospitalizations, according to data published by the Centers for Disease Control and Prevention (CDC). The CDC has linked vitamin E acetate, an adulterant typically reserved to the black market, to 48 of the 51 hospitalized patients it has examined. Governments have often responded to these contaminations by enacting bans on e‑cigarettes and other vaping products, but the CDC data suggest they should take the opposite approach.
