With advancing marijuana legalization in the United States, a primary concern is the possible increase in consequences relating to marijuana driving impairment, especially among people who use high-potency marijuana (i.e., extracts). In this study, the research team assessed the risk perception and experiences of driving under the influence of marijuana by investigating people who use extracts.
Participants from 2 studies were queried about driving after using marijuana. In Study 1, phone interviews (n = 19) were conducted with people who use extracts. In Study 2, people who use extracts (n = 174) were recruited to participate in a nationwide survey via an online existing panel. Responses to marijuana and driving-related questions were qualitatively coded for themes (e.g., riskiness, engagement in behavior) developed by the research team.
Prominent themes identified in Study 1 suggested a belief that driving risk following marijuana use is dependent on the individual (i.e., response/tolerance) or the amount/type of marijuana consumed. This theme was corroborated by Study 2 participants. Those who perceived no or minimal risk from driving following marijuana use were more likely to report engagement in driving following extracts use.
More research is needed to understand how marijuana, especially in its concentrated form, impacts driving ability in order to develop appropriate and scientifically sound regulations. Such research could subsequently fill the need to improve and more widely disseminate prevention messages on marijuana use and driving risks.
随着美国大麻合法化的推进，人们主要关注的是与大麻驾驶障碍相关的后果可能会增加，尤其是在使用高浓度大麻（即提取物）的人群中。在这项研究中，研究团队通过调查使用提取物的人群，评估了他们在吸食大麻后开车的风险感知和经历。
对来自两项研究的参与者进行了吸食大麻后开车的询问。在研究 1 中，对 19 名提取物使用者进行了电话访谈。在研究 2 中，通过在线现有小组招募了 174 名提取物使用者，参与全国性调查。研究团队对大麻和驾驶相关问题的回答进行了主题定性编码（例如，风险程度、行为参与）。
研究 1 中确定的突出主题表明，人们认为吸食大麻后开车的风险取决于个人（即反应/耐受性）或吸食的大麻数量/类型。研究 2 的参与者证实了这一主题。那些认为吸食大麻后开车没有或几乎没有风险的人更有可能报告在吸食提取物后开车。
为了制定适当和科学合理的法规，需要进一步研究大麻（尤其是浓缩形式）如何影响驾驶能力。这种研究可以随后满足改进和更广泛传播关于大麻使用和驾驶风险的预防信息的需求。
