A quitline is a helpline that provides free telephone counseling and support for individuals who want to quit smoking or using other tobacco products. Quitlines offer personalized coaching, information on quitting methods and resources, and ongoing support to help individuals successfully quit tobacco use. They may also provide referrals to additional support services, such as in-person counseling or medication assistance. Quitlines are typically staffed by trained counselors who can offer advice and guidance tailored to the individual's specific needs and situation. Research on quitlines often focuses on their effectiveness in helping people quit smoking, as well as ways to improve their reach and impact on public health.
