For the fifth consecutive year, Illinois is celebrating National Impaired Driving Prevention Month, which is designed to highlight the risks and consequences associated with driving a car after using alcohol or marijuana.  Motor vehicle crashes are the leading cause of death among teenagers in the United States.  In 2012, according to the Centers for Disease Control, 104 adolescents ages 12 to 20 in Illinois died of injuries from motor vehicle accidents.  According to the Illinois State Police, although teens only represent 10 percent of licensed drivers in the U.S., they are involved in or responsible for 17 percent of all alcohol related crashes.  Impaired driving has long term, sometimes fatal consequences for adolescent drivers, their families, and community.  Possible repercussions of a drunken or drugged driving crash include loss of life, serious brain or physical injuries, legal consequences or jail time, and long term emotional and mental health issues for the driver and others affected by the crash.  According to the 2012 Illinois Youth Survey, 38 percent of 12^th graders smoked marijuana in the last year.  Of these students, 1 in 5 reported driving after using marijuana or another illegal drug at least one time in the past year.  Although more teens use alcohol than marijuana, adolescents are more likely to drive after using marijuana because they do not think that marijuana use impairs their ability to drive.  As a drug that affects the brain and causes a high after use, marijuana use increases the risk for an accident because this behavior slows coordination and decision making, which negatively affects a teen’s ability to react to obstacles and be fully in control.  The Illinois State Police have increased patrols on holidays and nights when young people are more likely to be drinking.  Additionally, zero tolerance laws in Illinois can result in suspended licenses and legal consequences for teens if police find evidence of any alcohol or drug use.  For information on impaired driving and how you can help prevent impaired driving in your community, refer to Centers for Disease Controls resource guide at www.cdc.gov.
