The impacts of cannabis on driving performance were similar to those of low blood alcohol concentrations. Cannabis usage on its own minimizes lateral control of the vehicle (the ability to remain in the lane) even though motorists under the influence of marijuana slow their driving speed, perhaps in an attempt to compensate for their impaired state.
In contrast, alcohol usage on its own increases driving speed, which might indicate that chauffeurs under the influence of alcohol absence awareness of their impaired state. Alcohol likewise impacts a higher number of driving performance indications relative to marijuana, including increased crashes, lateral position irregularity, lane adventures, speed, and speed irregularity, along with reduced danger action time.
The combination of both drugs typically hinders the ability to preserve lane position more than either compound handled its own. The study discovered no proof that the 2 drugs neutralize each other on speed.
