Dear AJPM Reader,

As of 2019, about 1 in 7 U.S. adults was a current smoker, underscoring the ongoing need for tobacco cessation and control efforts. Our latest supplement, The Role of Quitlines in Tobacco Cessation, from the Centers for Disease Control and Prevention's Office on Smoking and Health, contains a collection of articles that examine the role of quitlines in reducing tobacco use.

Released in conjunction with the 10th anniversary of the CDC's Tips From Former Smokers® (Tips®) campaign, this special issue includes several articles that focus on reaching diverse populations for quitline enrollment both domestically and internationally. Other papers explore the role of technology in changing the quitline landscape. This includes innovations such as online registration for quitline services, which reaches a higher proportion of younger smokers, and an overview of the literature on quitline practices around e-cigarette use.

Further research in this issue considers how to tailor quitlines for specific groups. One article, for example, looks at the Asian Smokers' Quitline, which provides quitline services to smokers who speak Chinese, Korean, and Vietnamese. Another study examines outcomes and feasibility of quitlines tailored for people with mental health conditions, who smoke at 2 to 4 times the rate of those without such conditions.

AJPM has historically played a prominent role in publishing highly influential research on tobacco and nicotine use, cessation, and control, and we are pleased to add this supplement to our notable body of research on these topics.

We hope you find this supplement issue, as well as our March 2021 articles, to be timely, topical, and informative.

Yours in prevention and health,
