The University of California, San Francisco Quit the Hit Program is a digital vaping cessation initiative designed to help young adults quit nicotine use. It uses text messaging, personalized coaching, and behavioral strategies to support users through cravings and withdrawal. The program emphasizes harm reduction and gradual change rather than strict abstinence from the start. It is research-backed and tailored to meet the needs of teens and young adults, especially those using e-cigarettes.
