Objective

This study explored the associations of heavy alcohol consumption with current e-cigarette, cigarette and dual use of e-cigarettes and cigarettes among a nationally representative sample of adults in the United States (US), and if these associations are modified by marijuana use.

Methods

Data from 157,138 adults who participated in the 2020 Behavioral Risk Factor Surveillance System (BRFSS) were included in this cross-sectional analysis. Multinomial logistic regression was used to estimate the strength of the associations between heavy alcohol consumption (independent variable) and the tobacco use patterns (dependent variable, i.e., non-use, current e-cigarette use, current cigarette use and current dual use of e-cigarettes and cigarettes). We also assessed the interaction between past-month marijuana use and heavy alcohol consumption on the primary outcome.

Results

After the adjustment for potential confounders, heavy alcohol consumption (relative to no heavy alcohol consumption) was associated with higher odds of current e-cigarette (3.91 [2.25–6.78]), cigarette (3.02 [2.28–3.99]) and dual (4.78 [3.25–7.01]) use. The test for interaction showed that the associations of heavy alcohol consumption with the tobacco use patterns were modified by past-month marijuana use (p < 0.05 for all groups), with associations being much stronger among past-month marijuana non-users.

Conclusions

Heavy alcohol consumption is positively associated with current e-cigarette, cigarette, and dual use among US adults. Further, the findings indicate that these relationships are modified by past-month marijuana use. Longitudinal research is needed to explore the role of marijuana in the association of heavy alcohol consumption with current e-cigarette, cigarette and dual use among adults.

大麻的使用改变了美国成年人大量饮酒和烟草使用模式之间的关联：行为风险因素监测系统的调查结果，2020 年

客观的

这项研究探讨了在美国 (US) 具有全国代表性的成年人样本中大量饮酒与当前电子烟、香烟以及电子烟和香烟双重使用之间的关联，以及这些关联是否会因吸食大麻而改变。

方法

该横断面分析包括来自 2020 年行为风险因素监测系统 (BRFSS) 的 157,138 名成年人的数据。多项逻辑回归用于估计大量饮酒（自变量）与烟草使用模式（因变量，即不使用、当前使用电子烟、当前使用香烟和当前双重使用电子烟）之间的关联强度- 香烟和香烟）。我们还评估了过去一个月吸食大麻和大量饮酒对主要结局的影响。

结果

调整潜在混杂因素后，重度饮酒（相对于不重度饮酒）与当前电子烟 (3.91 [2.25–6.78])、香烟 (3.02 [2.28–3.99]) 和双重 (4.78) 的较高几率相关[3.25–7.01]) 使用。相互作用检验表明，重度饮酒与烟草使用模式之间的关联因过去一个月的大麻使用情况而改变（所有组的 p < 0.05），过去一个月的大麻非使用者之间的关联更为强烈。

结论

在美国成年人中，大量饮酒与目前电子烟、香烟和双重用途呈正相关。此外，研究结果表明，这些关系因过去一个月的大麻使用而改变。需要进行纵向研究来探索大麻在大量饮酒与当前电子烟、香烟和成人双重使用之间的关联中的作用。
