Localities have extended smoke-free policies to prohibit use of combustible and vaping products for nicotine/tobacco and cannabis (THC), but little is known about how this affects vaping behavior. We used Ecological Momentary Assessment to examine perceived exposure to smoking- and vaping-specific prohibitions and nicotine and THC vaping. Young adults (n = 178; age 25; 55 % male; 47 % Hispanic, 21 % Asian, 21 % White) in California who endorsed past-month use of nicotine and/or THC vaping products were recruited from an existing longitudinal study.
