There are many research studies showing that drunk driving is dangerous and leads to car crashes. There are also studies showing that some drugs are dangerous and can cause collisions. The research about marijuana, however, seems to be less clear. Now that Florida residents are considering Amendment 2 and other states are considering legalizing medical marijuana or decriminalizing marijuana, the debate has gained new ground.
Opponents of Amendment 2 have stated that legalizing or decriminalizing marijuana would lead to drugged driving. According to one coalition, Don’t Let Florida Go To Pot, one fourth of all fatal motor vehicle collisions can be linked to marijuana. The statistic comes from a 2011 White House Office of National Drug Control Policy report based on data from the National Highway Traffic Safety Administration’s (NHTSA) Fatality Analysis Reporting System. The data is based on fatal accidents between 2005 and 2009. According to that research, there were approximately 127,000 fatal car accidents across 50 states between those years and about 78,000 motorists were tested for drugs in these collisions. The research at the time showed that drivers who tested positive for marijuana use increased between 2005 and 2009, rising from 22.6% to 26% before declining to 25.3% in 2009.
