Concurrent use of cigarettes with e-cigarette or cannabis (co-use) is common. It is unclear whether people who want to quit smoking cigarettes would also be interested in quitting using e-cigarettes/cannabis (co-cessation).
In a survey of 391 Californian adults, participants reported past 30-day use of and intentions to quit cigarettes, e-cigarettes, and cannabis, and reasons for using e-cigarettes and/or cannabis. Using cross-tabulation tables, we examined the relationship between cigarette, e-cigarette, and cannabis cessation intentions. We subsequently examined how the reasons for using e-cigarettes and cannabis related to e-cigarette and cannabis use frequency, while controlling for cigarette use and demographic characteristics.
Of those who used both cigarettes and e-cigarettes and planned to quit smoking within the next 30 days, 68.9 % also planned to quit using e-cigarettes. Of those who used both cigarettes and cannabis and intended to quit smoking within 30 days, 30.0 % also wanted to quit using cannabis within the same period. Using e-cigarettes or cannabis to aid with cigarette cessation had no impact on e-cigarette or cannabis use frequency.
Those who intended to quit smoking cigarettes within 30-days also expressed interest in quitting e-cigarettes or cannabis within the same period. Using e-cigarettes or cannabis to quit smoking was not related to higher frequency e-cigarette or cannabis use. Future interventions may promote co-cessation of cigarettes, e-cigarettes, and cannabis simultaneously.
香烟与电子烟或大麻同时使用（共同使用）的情况很常见。尚不清楚想要戒烟的人是否也有兴趣同时戒掉电子烟/大麻（共同戒断）。
在一项对391名加利福尼亚成年人的调查中，参与者报告了过去30天内使用香烟、电子烟和大麻的情况以及戒烟、戒掉电子烟和大麻的意愿，以及使用电子烟和/或大麻的原因。通过交叉列表，我们研究了戒烟、戒掉电子烟和戒掉大麻意愿之间的关系。随后，我们在控制香烟使用和人口统计学特征的同时，研究了使用电子烟和大麻的原因与电子烟和大麻使用频率之间的关系。
在那些同时使用香烟和电子烟且计划在未来30天内戒烟的人中，68.9%的人也计划戒掉电子烟。在那些同时使用香烟和大麻且打算在30天内戒烟的人中，30.0%的人也希望在同一时期戒掉大麻。使用电子烟或大麻辅助戒烟对电子烟或大麻的使用频率没有影响。
那些打算在30天内戒烟的人也表示有兴趣在同一时期戒掉电子烟或大麻。使用电子烟或大麻戒烟与更高频率的电子烟或大麻使用无关。未来的干预措施可能会促进同时戒掉香烟、电子烟和大麻。
