New research tracing the effects of marijuana on driving shows results that suggest that cannabidiol (CBD) alone does not impair us in any way. This can be a significant determinant for legislators who are increasingly preparing regulations related to the legalization of marijuana in various parts of the world. With the rapidly changing rules of the medical and non-medical use of marijuana, driving while under the influence of marijuana is an important and controversial public concern. While some previous studies looked at the effects of marijuana on driving, the majority focused on smoking marijuana containing THC rather than CBD, and did not accurately indicate the duration of the impairment, says study author Iain McGregor of the University of Sydney.
There are over 100 different cannabinoids in marijuana, of which CBD and THC are the most significant - the latter is famous for its psychoactive euphoric effects. Meanwhile, CBD is more and more often indicated as a source of many positive health effects and recommended, for example, in reducing epileptic episodes - the American Food and Drug Administration has even approved the first ingredient with this substance. Therefore, there is also a need to investigate its effect, alone and in combination with THC, on driving as it can be expected that more and more people will use CBD.
The new study involved 26 volunteers whose driving ability was measured in 4 different scenarios - inhaling THC, inhaling CBD, combining THC and CBD, and placebo. The test involved driving on a real highway under controlled conditions for one hour 40 minutes after inhaling the substance and then 4 hours later. Impact on Driving was measured using a standard tool that estimates how often a driver drifted or drifted along the hoses within a designated lane and was previously used to measure the effects of alcohol and Valium on driving.
Compared to the placebo group, the researchers saw no effect on driving 40 minutes after inhaling CBD, which was noticeable, albeit mild, after THC and the combination of THC and CBD. Research indicates for the first time that CBD, when given without THC, does not affect driving ability. This is great news for people who are considering treatment with its use - adds the author. Interestingly, after 4 hours, none of the 4 scenarios had an impact on driving, confirming previous reports that marijuana does affect driving ability, but for a relatively short time. - Road safety is the main goal. The results should allow evidence-based law and regulation for those receiving medical marijuana, recententertainment author explains.
