Cannabis Doubles Risk Of Car Accidents

by | 25th, May 2007

DRIVING while under the infulence of cannabis doubles the risk of being involved in a fatal accident.

Researchers evaluated 10,748 fatal car accidents in France that had taken place between October 2001 and September 2003, and whose drivers had been tested for drug and alcohol levels.

They compared the 6,766 drivers deemed at fault for the crash with the other drivers who were considered blamelesss.

Cannabis was clearly linked with fatal accidents, with the risk rising as the concentration of delta-tetrahydrocannabinol (THC), the drug’s active ingredient, increased in the blood.

The odds ranged from 1.89 (almost double the risk) for a concentration of less than one nanogramme of THC per milliltre of blood, to 3.06 (more than triple the risk) for more than five ng/ml.

Should drivers be routinely tested for cannabis?
