背景：人们对大麻的可获得性与医用大麻法律的关系知之甚少。我们研究了医用大麻的法律（MML）和上个月大麻使用的流行率之间的关系，与感知的可用性marijuan.Methods：数据来自受访者包括在全国调查药物使用和健康限制使用数据门户2004-2013。使用个体水平数据的多水平逻辑回归来检验MML和非MML状态之间的差异以及在控制人口统计学的青少年、年轻人和老年人中，从MML通过之前到之后，过去一个月大麻使用和感知可用性的流行率的变化。在26岁以上的成年人中，MML通过后，上个月大麻使用的流行率从5.87%增加到7.15%（调整后的比值比（AOR）：1.24 11.16- 1.31 D，但12-17岁或18-25岁的使用率没有变化。MML在26岁以上人群中颁布后，大麻的可获得性增加，但在年轻群体中则没有。在所有年龄组中，大麻使用的流行率和对大麻容易获得的看法在2013年最终将通过MML的州比那些没有通过的州更高。感知的可用性显着相关的风险增加上个月大麻使用在所有年龄组。结论：证据表明，感知的可用性作为一个驱动程序的变化，由于MML大麻的使用。到目前为止，这种情况只发生在26岁以上的成年人中，需要进一步探索可以解释这种变化的不同情况。(C)2016爱思唯尔爱尔兰有限公司版权所有。
Background: Little is known on how perceived availability of marijuana is associated with medical marijuana laws. We examined the relationship between medical marijuana laws (MML) and the prevalence of past-month marijuana use, with perceived availability of marijuana.Methods: Data were from respondents included in the National Survey of Drug Use and Health restricted use data portal 2004-2013. Multilevel logistic regression of individual-level data was used to test differences between MML and non-MML states and changes in prevalence of past-month marijuana use and perceived availability from before to after passage of MML among adolescents, young adults and older adults controlling for demographics.Results: Among adults 26+, past-month prevalence of marijuana use increased from 5.87% to 7.15% after MML passage (Adjusted Odds Ratio (AOR): 1.24 11.16-1.31D, but no change in prevalence of use was found for 12-17 or 18-25 year-olds. Perceived availability of marijuana increased after MML was enacted among those 26+ but not in younger groups. Among all age groups, prevalence of marijuana use and perception of it being easily available was higher in states that would eventually pass MML by 2013 compared to those that had not. Perceived availability was significantly associated with increased risk of past-month marijuana use in all age groups.Conclusion: Evidence suggests perceived availability as a driver of change in use of marijuana due to MML. To date, this has only occurred in adults 26+ and different scenarios that could explain this change need to be further explored. (C) 2016 Elsevier Ireland Ltd. All rights reserved.
