As of 2015, more than half of U.S. states have legalized, medicalized, or decriminalized marijuana.
This study examined the prevalence and correlates of support for marijuana legalization in a national sample of young adults and the intention to use marijuana more frequently if it were legalized.
Data were from Wave 7 (weighted N = 3532) of the Truth Initiative Young Adult Cohort, a national sample of men and women aged 18-34. We assessed demographics, past 30-day substance (alcohol, tobacco, marijuana, other drug use), depression and anxiety, social smoking, marijuana harm perceptions (relative to cigarettes), and state-level marijuana policies as correlates of support for marijuana legalization and intentions to use marijuana more often if it were legalized. Multivariable models of correlates of support for legalization and intentions to use marijuana were conducted separately for the full sample and for nonmarijuana users.
Weighted estimates showed that 39% of the full sample and 9% of nonmarijuana users supported marijuana legalization. Multivariable models showed that lower marijuana harm perceptions and lifetime and past 30-day tobacco use were common predictors of support for marijuana legalization and intentions to use marijuana among non-users of marijuana. Conclusions/Importance: Over a third of the sample supported marijuana legalization. Tobacco use and perceptions that marijuana is less harmful than cigarettes were robust risk correlates of support for marijuana legalization and intentions to use more frequently among nonusers. Public health campaigns should target these factors to deter marijuana-related harm in susceptible young adults.
截至2015年，超过半数的美国州已将大麻合法化、医疗化或非刑罪化。
本研究在全国年轻成年人样本中调查了支持大麻合法化的流行情况及其相关因素，以及如果大麻合法化更频繁使用大麻的意愿。
数据来自真相倡议青年队列的第7波（加权N = 3532），这是一个全国性的18 - 34岁男性和女性样本。我们评估了人口统计学特征、过去30天的物质使用情况（酒精、烟草、大麻、其他药物使用）、抑郁和焦虑、社交性吸烟、大麻危害认知（相对于香烟）以及州级大麻政策，作为支持大麻合法化以及如果大麻合法化更频繁使用大麻意愿的相关因素。分别对全样本和非大麻使用者进行了支持合法化和使用大麻意愿相关因素的多变量模型分析。
加权估计显示，全样本中有39%以及非大麻使用者中有9%支持大麻合法化。多变量模型显示，较低的大麻危害认知以及终生和过去30天的烟草使用是大麻非使用者中支持大麻合法化和使用大麻意愿的常见预测因素。结论/重要性：超过三分之一的样本支持大麻合法化。烟草使用以及认为大麻比香烟危害小的认知是支持大麻合法化以及非使用者中更频繁使用大麻意愿的有力风险相关因素。公共卫生运动应针对这些因素以防止易感年轻成年人中与大麻相关的危害。
