Cigarette smoking continues to decline in the U.S., but cannabis use is increasing. Many people who smoke cigarettes also use cannabis. This study examines the characteristics of persons who co-use and those who do not co-use and the likelihood of quitting cigarettes for callers to Kick It California, a large state tobacco quitline.
Data were examined from Kick It California callers from January 2020 through December 2023 (N=45,151), including those from a subgroup randomly sampled and reached for evaluation at 7 months after quitline enrollment (n=3,545). The rate of cigarette smoking cessation at 7 months after enrollment for people who co-use cannabis was compared with that for people who do not. Analyses started in 2023 and concluded in January 2024.
More than a quarter (27.2%) of Kick It California callers co-used cannabis. They were more likely to be male, to be younger, and to have a mental health condition than those who did not. Those who co-use cannabis and those who do not have similar rates of receiving quitline counseling or using Food and Drug Administration-approved cessation aids. Controlled for effects of personal characteristics and use of smoking-cessation services, people who co-use cannabis were less likely to quit cigarette smoking 7 months after enrollment (23.2% vs 28.9%; p<0.001). Among those who co-use, 42.9% intended to quit using cannabis in the next 30 days.
A substantial percentage of tobacco quitline callers use cannabis. Those who do co-use quit cigarette smoking at a lower rate than those who do not. Over 40% of people who co-use reported intention to quit cannabis, making tobacco quitlines a rich environment to learn about people who co-use and develop strategies for intervention.
在美国，吸烟人数继续下降，但大麻的使用量却在增加。许多吸烟的人也使用大麻。本研究考察了同时使用大麻和不使用大麻的人的特征，以及拨打加利福尼亚戒烟热线（Kick It California）的人戒烟的可能性。
从 2020 年 1 月至 2023 年 12 月，对 Kick It California 呼叫者的数据进行了检查，包括从一个随机抽样并在戒烟热线注册后 7 个月进行评估的子组中（n=3545）。比较了大麻使用者和非大麻使用者在注册后 7 个月时的戒烟率。分析于 2023 年开始，于 2024 年 1 月结束。
超过四分之一（27.2%）的 Kick It California 呼叫者同时使用大麻。与不使用大麻的人相比，他们更有可能是男性，年龄更小，并且有心理健康问题。同时使用大麻和不使用大麻的人接受戒烟热线咨询或使用食品和药物管理局批准的戒烟辅助工具的比例相似。在控制个人特征和使用戒烟服务的影响后，同时使用大麻的人在注册后 7 个月戒烟的可能性较小（23.2%比 28.9%；p<0.001）。在同时使用大麻的人中，42.9%的人打算在接下来的 30 天内停止使用大麻。
相当一部分戒烟热线呼叫者使用大麻。同时使用大麻的人戒烟的比例低于不使用大麻的人。超过 40%的同时使用者报告打算在接下来的 30 天内停止使用大麻，这使得戒烟热线成为一个了解同时使用者并制定干预策略的丰富环境。
