 Electronic cigarettes, or e-sigs, have become the go-to device for smokers looking to quit. While it may be an effective mode of quitting, vaping presents many dangers on its own. Oils marketed for e-sigs may contain THC, which is illegal to consume for navy personnel. Additionally, ingesting high doses of THC can be harmful to your health. These oils, or e-juices, often have names such as hash oil, cannabis oil, and marijuana oil, and can be purchased online or in various vape stores. Beware of using other people's e-sigs as well. Whether you're at a bar, a party, or just hanging out at a friend's house, know what is in the e-sig that you're vaping. If you're thinking about quitting smoking, medical personnel are standing by to help. For more information on e-sigs, visit navy.mil.
