This study aimed to (i) describe concurrent and simultaneous tobacco and cannabis use and (ii) investigate the association between cannabis use and motivation and intentions to quit tobacco in a sample of socioeconomically disadvantaged smokers. A cross-sectional survey was conducted in 2013 and 2014 with current tobacco smokers receiving aid from two community service organizations in New South Wales, Australia. At least weekly cannabis use for the month prior to survey, motivation to quit tobacco and intentions to quit tobacco were measured in 369 participants (77% consent rate). Regressions were carried out to investigate associations between weekly cannabis use and motivation and intentions to quit tobacco.Concurrent tobacco and cannabis use was reported by 19% (n = 71) of the sample and of these users, 100% reported simultaneous use. Although regular cannabis use was significantly associated with lower motivation to quit tobacco, it was not significantly associated with intentions to quit tobacco in the next 30 days. Concurrent cannabis use is common in disadvantaged smokers and may play a role in decreased motivation to quit tobacco; however, it does not appear to be associated with intentions to quit in a sample of disadvantaged smokers.
（i）描述烟草与大麻的同时使用和同步使用情况；（ii）在社会经济地位不利的吸烟者样本中，调查大麻使用与戒烟动机及意愿之间的关联。2013年和2014年，对澳大利亚新南威尔士州两家社区服务机构提供援助的当前吸烟者进行了一项横断面调查。在369名参与者（同意率77%）中，测量了调查前一个月至少每周使用大麻的情况、戒烟动机和戒烟意愿。进行回归分析以调查每周使用大麻与戒烟动机及意愿之间的关联。样本中有19%（n = 71）的人报告同时使用烟草和大麻，在这些使用者中，100%报告为同步使用。尽管经常使用大麻与较低的戒烟动机显著相关，但与未来30天内的戒烟意愿无显著关联。在社会经济地位不利的吸烟者中，同时使用大麻的情况很常见，可能在降低戒烟动机方面起作用；然而，在社会经济地位不利的吸烟者样本中，这似乎与戒烟意愿无关。
