概括

怀疑大麻损伤的德国司机显示THC水平与驾驶损伤之间的相关性,但最终的切断值仍然难以捉摸. 新的3.5ng/mlTHC值可能会豁免许多司机.

科学领域:

法医毒理学法医毒理学
大麻研究大麻研究
道路交通安全道路交通安全

背景情况:

德国部分合法化大麻促使修订THC血清度限值.
对于司机来说,合法THC值从1ng/ml增加到3.5ng/ml.

研究的目的:

为了确定特定的THC血清度或大麻影响因子 (CIF) 是否表明驾驶障碍明显增加.
评估修订THC门对法律处罚的影响.

主要方法:

追溯分析740起 (2020-2021) 涉及涉嫌在大麻 (DUIC) 或大麻和酒精 (DUIAC) 影响下驾驶的司机的案件.
评估行为和驾驶障碍,THC血清度,CIF值和血中酒精度 (BAC),如适用.

主要成果:

大麻使用显然会损害精神运动和认知功能,THC水平与驾驶障碍之间存在粗略的相关性.
没有明确的切断THC值被确定,这意味着由于大量重叠而导致损失的显著增加.
在刑事犯罪案件 (§316 德国刑法) 中,THC和CIF值略高,但差异太小,无法可靠地切断.
应用新的3.5ng/mlTHC值意味着大约三分之一的评估案例不会面临处罚.

结论:

虽然THC血清度和损伤之间存在关系,但它太弱,无法建立一个科学有效的切断值.
德国修订后的3.5ng/ml的THC法定值可能会大大减少因大麻损害而受到处罚的司机数量.

Drug Regulation

Drug Regulation

Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...

Mutagenicity and Carcinogenicity

Mutagenicity and Carcinogenicity

Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.

Toxicity Testing in Animals

Toxicity Testing in Animals

Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
