Blow your mind - crash your car

Comment on this story
IOL mot pic feb10 Smoking Weed 1 REUTERS People who smoke marijuana and drive twice as likely to kill themselves, or somebody else.

Drivers who smoke marijuana within three hours of getting behind the wheel run almost double the risk of a serious crash.

A major review of accident data involving 50 000 drivers has revealed that those who have taken the class B drug are far more likely to be involved in a collision with another vehicle.

It comes amid growing concern about the influence of drugs on road safety, particularly among young drivers.

The latest research, published in the British Medical Journal, singled out drivers who tested positive for marijuana through blood tests, or who admitted using the drug before an accident.

It found that smoking marijuana resulted in a ‘near doubling of risk of a driver being involved in a collision resulting in serious injury or death’.

The researchers, from Dalhousie University in Canada, said: “The results also agree with recent data that point to the increasing presence of drugs other than alcohol (especially cannabis and depressants) in injured and fatally injured drivers.’

In the UK, drug-driving laws are to be tightened, with the possible introduction of roadside ‘drugalysers’, after a campaign by the family of 14-year-old Lillian Groves, who was run over and killed by a driver high on drugs in 2010.

Road safety minister Mike Penning said: ‘Drug-driving is a menace, which is why we are going to introduce a new drug-driving offence.’ - Daily Mail

http:www.newscientist.commobilearticledn2063-alcohol-impairs-driving-more-than-marijuana.html What load of crap...check da link for british research as the article is based on british research...u can google it and will find similar results from australia,israel and a few american universities. Smokers are more aware of their state of mind and compensate by lowering speeds.

I do not know how authentic this study is, but i can tell that people love their marijuana. I think it will be better to have drivers on the road who are stoned than the usual aggressive b*stards who behave like the earth owes them something.

ADDITIONAL DATA: * Relative risk of vehicle collision whilst under the 'acute' influence of cannabis is 1.92 whilst the relative risk of a similar vehicle accident with a blood alcohol content of 0.8 g100 mL (the legal limit in many places) is 2.69.http:www.bmj.comcontent344bmj.e536 * A driver with a blood alcohol concentration (BAC) of 0.10 or greater is seven times more likely to be involved in a fatal motor vehicle crash than is a driver who has not consumed alcoholic beverages, and a driver with an alcohol concentration of 0.15 or greater is about 25 times more likely. * In a 60 kmh zone the risk of involvement in a vehicle accident with casualties increases exponentially (doubles) with each 5 kmh increase in traveling speed. * Talking on a Cell phone while driving Increases accident risk by a factor of 4. * Texting while driving Increases accident risk by a factor of 23. * Eating and drinking is a factor in more accidents than DUI, cell phone use or texting while driving. * The smokers of cigarettes - even if they do not smoke while driving - have an increased accident risk of 1.5 * Smoking cigarettes while driving Increases accident risk by a factor of 2. * Alcohol-related accidents are so prevalent, an estimated 40 percent of all persons in the United States will be involved in a traffic mishap blamed on alcohol at some point in their lives.*** It is important to note that once marijuana is 'Legalized and Regulated', it will still be an offense to drive while impaired - DUI laws already apply to marijuana just like they do alcohol. The fact that being under the influence of a substance makes you a worse driver should have no bearing on its legality in general - otherwise we would be forced to hand the market in alcohol back to machine-gun tooting bootleggers.

NEW STUDY: On 29-Nov-2011, a study was published by University of Colorado Denver Professor Daniel Rees and Montana State University Assistant Professor D. Mark Anderson showing states that have legalized medical marijuana experience fewer fatal car crashes compared to states that have not. The researchers suggest that there may be fewer fatal drunk driving accidents in those jurisdictions because more people may be choosing to smoke marijuana instead of making the more dangerous choice of consuming alcohol - both traffic fatalities and alcohol consumption declined. The rate of fatal crashes in which a driver had consumed any alcohol dropped 12% after medical marijuana was legalized, and crashes involving high levels of alcohol consumption fell 14%. The study thoroughly accounted for other contributing factors regarding this decrease, such as changes in the number of miles traveled each year and new traffic laws. “Our research suggests that the legalization of medical marijuana reduces traffic fatalities through reducing alcohol consumption by young adults,” - Daniel Rees, professor of economics at the University of Colorado Denver who co-authored the study with D. Mark Anderson, assistant professor of economics at Montana State University. So, the prohibitionist scare-tactic of claiming there would be an increase in traffic fatalities if marijuana were to be legally regulated for all adults should now be banished to the fantasy realm from whence it came.

I drive stoned 95% of the time I'm on the road, which is a lot. I always roll a joint for the road. I've been doing this every day for 6 years. The only time I've crashed was when I decided to drive drunk.

I do believe that the persons who compiled the research data and made these conclusions were all stoned out of their skulls.

So true I had a number of close calls when stoned. More so than when drinking. Some people manage it better, but most stoners I know are not very good drivers.

This is such a bogus conclusion if you actually start reading the study, which can be downloaded from the BMJs website for free: http:www.bmj.comcontent344bmj.e536 "Across studies, the main bias related to exposure measurement was the concurrent use of alcohol or other drugs in addition to cannabis. Although data were available for alcohol, insufficient information was available to account for the effect of other illicit drugs. Since this bias would overestimate the effect of cannabis on collision risk, we calculated odds ratios using “cannabis only” cases and controls—that is, only those motorists whose system contained cannabis without any other drugs or alcohol present. Few of the people in the accidents reported in the studies had only smoked cannabis. Most had at least alcohol as well in their system. Yet this BS piece is getting plastered all over.

Normal people have recently discovered that media often releases unsubstantiated rubbish in the hopes that some idiots would blindly accept it as fact. http:www.bmj.comcontent344bmj.e536 is the link the the published study. (thanks iol) Unfortunately after reading through, i find no conclusions, only suggestions based on cherry picked data. I think the conclusion is in the article though, more laws, now they will not only breathalyse you, but test your pee too. Of course, it won't solve accidents, but i'll bet it will increase the revenue stream for the fat pigs. How about we ban road safety ministers, in this country at least, they're the biggest problem.

Typical media rubbish. gives the good stuff more bad name, like alcohol rather deserves, oh and btw Alcohol kills, weed does not. not a single cause of death or report ever recorded that points the use of weed that kills.

Amen Andrew and others who said similar thing. A smoker will be too paranoid to drive like an idiot. Unlike Enough Alcohol that makes you feel like you're untouchable or donut King of the road with your own rules & moves, or actually anything goes for some people who get drunk. Alcohol does way more damage in general than weed ever will. Even if you smoke the whole day and everyday. You cant do the same alcohol.

If our president can smoke it(he has admitted it himself before), why cant me? Stop the propaganda and just make it legal already. Way too much time is spent by police chasing down dagga. Let them focus on real criminals instead.

What is interesting is that not one of the usual vehement anti-marijuana folks have commented on this. Most likely because not one of them has anything to prove such lies. Fact is that the world has been force fed this garbage propaganda that this plant is evil and bad for you for so long that some people just cannot see or accept the truth. But hey, let those people carry on drinking and driving and calling pot smokers the bad ones... see if I care.
