Researchers at Columbia University say that drivers who smoke marijuana and drive within three hours of using it are two times more likely than other drivers to become involved in an automobile accident, according to a recent post on USA Today. They also said that users face higher risks of crashes if they smoke it more often or have larger concentrations of marijuana compounds in their blood.
The researchers’ findings are shown in a recent journal review showing that in eight of nine studies done drivers were at twice the risk for vehicle crashes. These are significant findings since national debate is heating up over the issue of legalizing marijuana. A recent Gallup poll shows that half of adult Americans favor the legalization of marijuana and that number is up from just 36 percent in 2006.
Statistics show that marijuana was the most commonly found substance those drivers in vehicle accidents tested positive for when testing for non-alcoholic drugs. Analysis showed that of the 28 percent killed in vehicular accidents, over 11 percent of the general population of drivers tested positive for drugs other than alcohol and marijuana was most common.
Professor Guohua Li at Columbia University says that if these facts are further confirmed by more research, this will have major impact on driving safety and the public policy that surrounds it. Furthermore, it would play a key role when it comes to policy making and the use of medical marijuana, says Li.
This is quite a large problem and if more states like California allow the medical use of marijuana, it could grow even bigger. In 2009 the National Survey on Drug Use and Health estimated that over 10 million people ages 12 and up have driven while under the influence of illegal drugs.
