概括
蒸汽大麻和烟草一起显著增加了THC和尼古丁的暴露. 尼古丁可能会减轻THC的影响,因为主观体验和心率在混合物和单独大麻之间没有区别.
科学领域:
- 药理学和毒理学 药理学和毒理学
- 大麻和烟草研究研究
- 蒸发器技术 蒸发器技术
背景情况:
- 同时使用大麻和烟草很普遍.
- 了解蒸汽这些物质的综合影响对于公共卫生至关重要.
- 蒸发器设备提供了一种可控的物质管理方法.
研究的目的:
- 为了比较Δ-9-四大麻 (THC) 和尼古丁摄入量,药理动力学和生理效应.
- 为了研究只有大麻,只有烟草和50:50混合物的vaping效应.
- 评估对不同蒸汽条件的主观和生理反应.
主要方法:
- 八名健康的成年人同时使用大麻和烟草,参与了个体内研究.
- 参与者使用PAX-3蒸发器蒸发了标准剂量的大麻,烟草或大麻-烟草混合物.
- 采集了血液样本,并在vaping之前和之后进行了问卷调查.
主要成果:
- 与单一物质使用相比,蒸汽混合物导致血THC和尼古丁度 (Cmax和AUC) 显著增加.
- 血THCCmax和AUC在混合物中比单独使用大麻更高.
- 血尼古丁Cmax和AUC与混合物相比,单独使用烟草更高.
结论:
- 同时吸食大麻和烟草会增加对THC和尼古丁的暴露.
- 尼古丁可能会减轻THC的主观影响和生理影响,如在混合条件中观察到的.
- 需要进一步研究更大的样本大小来证实这些发现,并了解组合使用的影响.

Stimulants
130
Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids
184
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.
