Marijuana has become the most commonly detected non-alcohol substance among drivers in the United States and Europe. Use of marijuana has been shown to impair driving performance and increase crash risk. Due to the lack of standardization in assessing marijuana-induced impairment and limitations of zero tolerance legislation, more jurisdictions are adopting per se laws by specifying a legal limit of Δ-tetrahydrocannabinol (THC) at or above which drivers are prosecuted for driving under the influence of marijuana. This review examines major considerations when developing these threshold THC concentrations and specifics of legal THC limits for drivers adopted by different jurisdictions in the United States and other countries.
大麻已成为美国和欧洲司机中最常被检测出的非酒精类物质。使用大麻已被证明会损害驾驶性能并增加撞车风险。由于评估大麻所致损害缺乏标准化以及零容忍立法存在局限性，越来越多的司法管辖区正在通过规定Δ-四氢大麻酚（THC）的法定限量来采用本身违法法律，达到或超过该限量的司机将因受大麻影响驾驶而被起诉。本综述探讨了制定这些THC阈值浓度时的主要考量因素以及美国和其他国家不同司法管辖区采用的针对司机的法定THC限量详情。
