As legal recreational marijuana use expands rapidly across the U.S., there is growing concern that this will lead to higher rates of use among college-aged young adults. Given the limited research addressing this issue, a longitudinal study was conducted to evaluate the effects of legalizing recreational use on the attitudes, intentions, and marijuana use behaviors of college students in two different legalization contexts, Washington State and Wisconsin.
Survey data assessing marijuana attitudes, intentions, and use behavior were collected from 2011 to 2016 on a longitudinal cohort of 338 students at two large public universities in Washington and Wisconsin. Time series analyses were conducted to evaluate postlegalization changes in ever use, 28-day use, and mean attitude and intention-to-use scores in Washington state, using Wisconsin participants as the control group.
Ever use, attitude, and intention-to-use scores did not change significantly more in Washington after legalization than in Wisconsin. However, among prior users, the proportion using in the last 28 days rose faster in Washington after legalization that it did in Wisconsin (p < .001).
The findings suggest that legalization had the greatest effects on current marijuana users, who are surrounded by a climate that is increasingly supportive of its use.
随着美国各地合法娱乐用大麻的使用迅速增加，人们越来越担心这将导致大学生群体中更高的使用率。鉴于针对这一问题的研究有限，进行了一项纵向研究，以评估娱乐用大麻合法化对两个不同合法化背景下（华盛顿州和威斯康星州）大学生的态度、意图和大麻使用行为的影响。
在 2011 年至 2016 年期间，对来自华盛顿和威斯康星州两所大型公立大学的 338 名学生进行了一项纵向队列研究，收集了关于大麻态度、意图和使用行为的调查数据。使用威斯康星州的参与者作为对照组，对时间序列分析进行了评估，以评估在华盛顿州合法后对以往使用、28 天使用以及平均态度和意图使用评分的变化。
在合法后，华盛顿州的以往使用、态度和意图使用评分的变化并不比威斯康星州显著更多。然而，在以往使用者中，在合法后过去 28 天内使用的比例在华盛顿州比在威斯康星州增长更快（p < 0.001）。
研究结果表明，合法化对当前大麻使用者的影响最大，他们所处的环境越来越支持大麻的使用。
