Marijuana, cannabis, weed or Indian hemp refers to the plant(leaves, flowers, stems and seeds) from the cannabis sativa plant. The plant contains the tetrahydrocannabinol which alters human mind. It is the most commonly used psychotropic after alcohol in most countries of the world. Marijuana and driving refers to the effects of marijuana consumption on driving. It also involves how the intake of it affects the behavioural pattern of driver’s while using the roads.
The intake of marijuana affects areas of the brain that controls the body’s movements, balance, coordination, memory and judgment abilities as well as sensations.
Marijuana And Driving Effects
A meta-analysis of approximately 60 experimental studies including laboratory driving simulator and on the road experiments, found that behavioural and cognitive skills related to driving performance were impaired in a dose-dependent fashion with increasing marijuana blood levels.
Record from experiments on both real and simulated driving studies indicates that marijuana can negatively impact on driver’s attentiveness, perception of time and speed and the ability to draw on information obtained through past experiences.
Research shows that impairment increases significantly when marijuana use is combined with alcohol.
Moreso, the user driver is still likely to suffer proper driving coordination issue even after the marijuana highness is gone. It’s as bad as that.
