E-cigarette addiction, also known as vaping addiction, is a condition in which a person becomes physically and psychologically dependent on nicotine delivered through an e-cigarette device. E-cigarettes are electronic devices that heat a liquid containing nicotine, flavorings, and other chemicals into an aerosol that is inhaled by the user. The addictive nature of nicotine in e-cigarettes can lead to changes in brain chemistry and the development of dependence. Treatment options for e-cigarette addiction may include nicotine replacement therapy, counseling, and support groups. Prevention strategies include avoiding e-cigarettes altogether, seeking professional help for underlying psychological or relationship issues, and developing healthy coping mechanisms.
