Positive Marijuana Result Not Associated With Auto Crash Culpability

Paranoid Pot Smokers Drive More Carefully

Alcohol Impairs Driving More Than Marijuana

Cannabis May Make You a Safer Driver

U.S. Department of Transportation, National Highway Traffic Safety Administration
(DOT HS 808 078), Final Report, November 1993:
"THC's adverse effects on driving performance appear relatively small"

While it is widely accepted that cannabis use can slow motor skills and reduce task-attention, increasing in severity with dose, research has shown that cannabis use is less likely to dangerously impair driving abilities than alcohol at similar levels of intoxication. Cannabis intoxication often makes smokers more aware of their impairment, causing them to slow down and become more cautious while also worsening reaction time and attention. Cannabis users often report that driving speeds are experientially 'faster' than normal: driving a given speed feels faster and more dangerous than the same speed does while sober.

There have been a number of studies which have looked at this issue and most have found that cannabis smoking does degrade driving performance. There is a little contradictory evidence about whether cannabis in combination with alcohol causes worse impairment than alcohol alone, but so far the data heavily favors the view that the combination substantially increases risks over either alone.

The research so far does not provide a clear answer to how much risk of accidents increase with moderate levels of cannabis intoxication, but only confirms that the risks of cannabis-alone impairment are lower than those of alcohol-alone impairment. The following are a collection of summaries & papers which look at the issue of cannabis & driving performance.

Alcohol impairs driving more than marijuana

A single glass of wine will impair your driving more than smoking a joint. And under certain test conditions, the complex way alcohol and cannabis combine to affect driving behaviour suggests that someone who has taken both may drive less recklessly than a person who is simply drunk.

Marijuana Myth: "Marijuana Is A Major Cause Of Highway Accidents"

MARIJUANA DOES NOT CAUSE RECKLESS DRIVING
The White House Office of National Drug Control Policy (ONDCP) and certain Wisconsin legislators have launched a new crusade against "drugged driving," with a heavy emphasis on marijuana. This crusade is largely based on scientific misinformation, and it could lead to the enactment of bad laws.

there are significantly more errors for alcohol intoxicated than for control subjects"

Antidrug Ad Blitz Criticized For Omitting Alcohol!

ONDCP has several slick television commercials on the subject. One shows dramatic auto accidents and two crash test dummies passing a joint while a serious voice says, "In a recent study, one in three reckless drivers tested positive for marijuana." Note the careful phrasing. The idea is to make viewers think that marijuana caused the reckless driving, without really saying that it did.
