Abstract

Background

Co-use of cannabis and tobacco is increasing, but its impact on smoking cessation is not completely understood. It is unclear whether any cannabis use, or only problematic use such as cannabis use disorder (CUD), impacts smoking cessation.

Method

In 2023, we conducted an online, national survey of US adults (n = 2,271) currently smoking cigarettes. We examined the association of past 30-day cannabis use (divided into three groups: co-use with CUD, co-use without CUD, and no cannabis use) with outcomes that can impact smoking cessation: self-rated importance, readiness, and confidence in quitting, barriers to cessation (Barriers to Cessation Scale, score range 0 to 57), and specific types of barriers (Addiction, Internal, and External barriers subscales).

Results

Interest in quitting smoking and self-rated importance was lowest in those with co-use without CUD, but self-rated readiness and confidence did not significantly differ among the three groups. Those with CUD reported the highest levels of barriers overall (total score of 20.3 for co-use with CUD, 15.2 for co-use use without CUD, and 16.4 for no cannabis use) and across all subscales. Adjusted subscale scores were higher for adults with CUD vs. cannabis use without CUD (Addiction: p = 0.03, External: p= 0<.001, Internal: <.001) and vs. no cannabis use (Addiction: p = 0.03, External: p = 0.02, Internal: p < 0.001).

Conclusions

Adults who smoke cigarettes and use cannabis (vs. those smoking without cannabis co-use) report similar levels of readiness and confidence in quitting smoking. However, interest in and importance of quitting smoking was lowest in those reporting co-use without CUD and barriers were greatest in those reporting co-use with CUD. These populations may benefit from targeted interventions to address their unique challenges and improve smoking cessation.

大麻共同使用和大麻使用障碍对戒烟兴趣和障碍的影响。

背景：大麻和烟草的共同使用正在增加，但其对戒烟的影响尚未完全了解。目前尚不清楚是否有任何大麻使用，或者只是有问题的使用，如大麻使用障碍（CUD），影响戒烟。方法：在2023年，我们对目前吸烟的美国成年人（n = 2271）进行了一项在线全国调查。我们研究了过去30天的大麻使用（分为三组：与CUD共同使用、不与CUD共同使用和不使用大麻）与影响戒烟的结果的关联：自我评定的重要性、戒烟准备和信心、戒烟障碍（戒烟障碍量表，得分范围为0至57）和特定类型的障碍（成瘾、内部和外部障碍亚量表）。结果：戒烟兴趣和自评重要性在无CUD的共用组中最低，但自评准备度和信心在三组之间无显著差异。CUD患者报告的障碍总体水平最高（与CUD共同使用的总分为20.3，未CUD共同使用的总分为15.2，不使用大麻的总分为16.4），并且在所有子量表中都是如此。与未使用大麻的成年人相比，有CUD的成年人调整后的亚量表得分更高（成瘾：p= 0.03，外部：p= 0）结论：吸烟和使用大麻的成年人（与不同时使用大麻的成年人相比）报告的戒烟准备和信心水平相似。然而，对戒烟的兴趣和重要性在未合并CUD的患者中最低，而在合并CUD的患者中戒烟障碍最大。这些人群可能受益于有针对性的干预措施，以解决其独特的挑战并改善戒烟。

期刊介绍： Addictive Behaviors is an international peer-reviewed journal publishing high quality human research on addictive behaviors and disorders since 1975. The journal accepts submissions of full-length papers and short communications on substance-related addictions such as the abuse of alcohol, drugs and nicotine, and behavioral addictions involving gambling and technology. We primarily publish behavioral and psychosocial research but our articles span the fields of psychology, sociology, psychiatry, epidemiology, social policy, medicine, pharmacology and neuroscience. While theoretical orientations are diverse, the emphasis of the journal is primarily empirical. That is, sound experimental design combined with valid, reliable assessment and evaluation procedures are a requisite for acceptance. However, innovative and empirically oriented case studies that might encourage new lines of inquiry are accepted as well. Studies that clearly contribute to current knowledge of etiology, prevention, social policy or treatment are given priority. Scholarly commentaries on topical issues, systematic reviews, and mini reviews are encouraged. We especially welcome multimedia papers that incorporate video or audio components to better display methodology or findings. Studies can also be submitted to Addictive Behaviors? companion title, the open access journal Addictive Behaviors Reports, which has a particular interest in ''non-traditional'', innovative and empirically-oriented research such as negative/null data papers, replication studies, case reports on novel treatments, and cross-cultural research.
