Many Teens Driving Under Influence of Marijuana

March 7, 2012 RSS Feed Print

One in five teen drivers surveyed in a recent poll has admitted to driving under the influence of marijuana, according to a recent study by Liberty Mutual Insurance and Students Against Destructive Decisions (SADD). And many of these teenagers don't seem to think driving while high is a big deal. Thirty-six percent of teens who have driven high say marijuana doesn't distract them from driving, the report continues.

But marijuana does seem to affect drivers. Pot is the most common illegal drug found in drivers who die in car accidents, according to "Marijuana: Facts for Teens," a booklet published in 2001 and most recently revised in March 2011 by the National Institute on Drug Abuse.

"Marijuana affects a number of skills required for safe driving—alertness, concentration, coordination, and reaction time—so it's not safe to drive high or to ride with someone who's been smoking [pot]," the NIDA booklet continues. High drivers have a hard time judging distances and reacting to signals and sounds, NIDA adds.

Driving high is a growing trend among teens, according to Liberty Mutual and SADD, and it's not hard for teens to find the materials to get high in the first place.

"Marijuana has remained a highly accessible drug," states the "2011 Monitoring the Future" report, conducted by NIDA and the University of Michigan Institute for Social Research. Sixty-eight percent of 10th graders and 82 percent of high school seniors surveyed said they could get pot fairly easily if they wanted some, the report says.

If a teenager obtains marijuana, gets high, and then jumps behind the wheel of a car, it's often up to the passenger to speak up. With drunk drivers, 87 percent of teen passengers reported to Liberty Mutual and SADD that they would ask the drunk person to refrain from getting behind the wheel.

However, teens are less likely to voice their concerns to a driver who's under the influence of marijuana. Seventy-two percent of teen passengers would speak up to a high driver, according to the report by Liberty Mutual and SADD.

But confronting a driver under the influence of marijuana could be lifesaving. Most teen drivers (90 percent) reported to Liberty Mutual and SADD that they would stop driving high if asked by their passengers.

Finding the words and courage to confront a high driver can be hard for a teen, and the report by Liberty Mutual and SADD notes that women are more likely to do so than men. Parents, teachers, and others should be open to the discussion of drugs, said Liberty Mutual driving expert Dave Melton in the report. Specifically, adults and teens can practice scenarios in which a teen must confront a high driver.

"It's our job as mentors, parents, role models, or friends to effectively communicate with [teens] to ensure they are armed with the right information and aware of the dangers of marijuana and other substances," Melton said in the report. "Especially while driving."

A 2002 review of seven separate crash culpability studies involving 7,934 drivers reported, “Crash culpability studies [which attempt to correlate the responsibility of a driver for an accident to his or her consumption of a drug and the level of drug compound in his or her system] have failed to demonstrate that drivers with cannabinoids in the blood are significantly more likely than drug-free drivers to be culpable in road crashes.” [Chesher et al. Cannabis and alcohol in motor vehicle accidents. In: Grotenhermen and Russo (Eds) Cannabis and Cannabinoids: Pharmacology, Toxicology, and Therapeutic Potential. New York: Haworth Press. 2002: 313-323.]

But, unlike with alcohol, the accident risk caused by cannabis, particularly among those who are not acutely intoxicated, appears limited because subjects under its influence are generally aware of their impairment and compensate to some extent, such as by slowing down and by focusing their attention when they know a response will be required. [Allison Smiley. Marijuana: On-Road and Driving Simulator Studies]

This response is the opposite of that exhibited by drivers under the influence of alcohol, who tend to drive in a more risky manner proportional to their intoxication.[United Kingdom's Advisory Council on the Misuse of Drugs. The Classification of Cannabis Under the Misuse of Drugs Act of 1971. 2002: See specifically: Chapter 4, Section 4.3.5: "Cannabis differs from alcohol; ... it seems not to increase risk-taking behavior. This may explain why it appears to play a smaller role than alcohol in road traffic accidents."]

Studies have shown marijuana users are Safer Drivers than either drunk drivers, or sober ones.

http://blogs.lawyers.com/2012/04/cruising-the-high-way-safer-than-drunk-driving/

One study, entitled "Medical Marijuana Laws, Traffic Fatalities, and Alcohol Consumption" conducted in November 2011 provides evidence that marijuana is a safer substitute for alcohol when it comes to health and also makes for safer drivers.

Top Ten Reasons Marijuana Users Are Safe Drivers

When you combine all of the main results of these two decades worth of scientific research studies, the following 10 reasons marijuana drivers are safer than drunk drivers comes out like this:

1. Drivers who had been using marijuana were found to drive slower, according to a 1983 study done by U.S. National Highway Transportation Safety Administration (NHTSA). This was seen as a factor in their favor, since drivers who drank alcohol usually drove faster and that is part of the reason they had accidents.

2. Marijuana users were able to drive straight and not have any trouble staying in their own lanes when driving on the highway, according to a NHTSA done in 1993 in the Netherlands. The study determined also that the use of marijuana had very little effect on the person’s overall driving ability.

3. Drivers who had smoked marijuana were shown to be less likely to try to pass other cars and to drive at a consistent speed, according to a University of Adelaide study done in Australia. The study showed no danger unless the drivers had also been drinking alcohol.

4. Drivers high on marijuana were also shown to be less likely to drive in a reckless fashion, according to a study done in 2000 in the UK by the UK Transport Research Lab. The study was done using drivers on driving simulators over a period of a month and was actually undertaken to show that pot was a cause for impairment, but instead it showed the opposite and confirmed that these drivers were actually much safer than some of the other drivers on the road.

5. States that allow the legal use of marijuana for medical reasons are noticing less traffic fatalities; for instance, in Colorado and Montana there has been a nine percent drop in traffic fatalities and a five percent drop in beer sales. The conclusion was that using marijuana actually has helped save lives. Medical marijuana is allowed in 16 states in the U.S.

6. Low doses of marijuana in a person’s system was found by tests in Canada in 2002 to have little effect on a person’s ability to drive a car, and that these drivers were in much fewer car crashes than alcohol drinkers.

7. Most marijuana smokers have fewer crashes because they don’t even drive in the first place and just stay home thus concluded more than one of these tests on pot smoking and driving.

8. Marijuana smokers are thought to be more sober drivers. Traffic information from 13 states where medical marijuana is legal showed that these drivers were actually safer and more careful than many other drive

My teen thinks that because she is an advanced, honors student and takes on a lot of responsibility at home. She can cook and clean as well as I do, those things give her the Green light to smoke pot at the ages of 14-15, now, she is 16. I didn't know until 6 months ago she started so young. I watch my girls and I didn't allow them to spend the night away from home very often and I always waited up til they got home so that I could look at them to make sure there was no drugs or Alcohol. I need help to get her to see how dangerous and destructive her behavior is.
