About Us

The California Smokers’ Helpline (1-800-NO-BUTTS) is a free statewide quit smoking service operated by the University of California San Diego's Moore's Cancer Center. The Helpline offers self-help materials, referral to local programs, and one-on-one, telephone counseling to quit smoking. Helpline services have been proven in clinical trials to double a smoker’s chances of successfully quitting.

Services are available in six languages (English, Spanish, Cantonese, Mandarin, Korean, and Vietnamese) and specialized services are also available for teens, pregnant women, and tobacco chewers. The Helpline also provides information to friends and family members of tobacco users.

Hours of operation are Monday through Friday from 7 am to 9 pm, and Saturday and Sunday from 9 am to 5 pm. Voicemail and recorded messages are available 24 hours a day.

The California Smokers’ Helpline is funded by the California Department of Public Health, Tobacco Control Program through Prop 99, the 1988 Tobacco Tax Health Protection Act, and Proposition 10, the California Children and Families Act enacted in 1998 at the local and state levels.
