These maps show where drugs and alcohol kill the most American motorists

Between 1995 and 2013, drugs and alcohol were involved in 26% of all fatal car accidents, claiming 267,598 lives, according to a new study by Florida drug publication, DrugTreatment.com.

The group recently analysed that 18-year span using data from the National Highway Traffic Safety Administration (NHTSA) to determine where substance abuse plays a significant role in fatal car accidents.
