A study conducted by scientists from Columbia University (USA) showed that in 2010, about 10 million people aged 12 and over got behind the wheel of a car while under the influence of drugs. In their study, the scientists tried to find a link between the use of drugs such as marijuana and the risk of road accidents.
Drivers who tested positive for marijuana or admitted to driving within three hours of using cannabis were found to be twice as likely to be involved in a traffic accident. A link was also found between the level of marijuana metabolites in urine and the likelihood of a traffic accident.
The study's findings showed that about 30% of traffic fatalities and 11% of all drivers were found to be using drugs, most commonly marijuana.
Let us recall that earlier scientists demonstrated a connection between the occurrence of mental disorders in later life and episodic "smoking of weed". There were also reports that genetically modified marijuana had appeared on the market.
