Parents can make a meaningful difference in preventing nicotine and cannabis vaping, starting with understanding what vaping is and how to support their teen. Vaping is the use of an electronic device, such as an e-cigarette or vape pen. These devices may contain nicotine, cannabis compounds such as THC or CBD, flavorings, and other chemicals, which can impact a teen’s health and brain development. A variety of factors can influence a teen’s decision to vape, but having conversations with teens, supporting healthy coping strategies, and practicing safe storage can help to make healthy choices easier for teens.
