First Of Its Kind Study Finds Virtually No Driving Impairment Under The Influence Of Marijuana

As marijuana restriction laws fall apart day by day, it's permitting more research to be carried out on this psychoactive compound that has actually long belonged of the human experience.

The first research to analyze the impacts of marijuana on driving efficiency discovered that it caused nearly no problems. The problems that it did cause resembled that observed under the impact of a legal alcohol limitation.

Scientists at the University of Iowa's National Advanced Driving Simulator performed the study, sponsored by National Highway Traffic Security Administration, National Institute of Substance abuse, and the Workplace of National Drug Control Policy

“Once in the simulator—a 1996 Malibu sedan mounted in a 24-feet diameter dome—the drivers were assessed on weaving within the lane, how often the car left the lane, and the speed of the weaving. Drivers with only alcohol in their systems showed impairment in all three areas while those strictly under the influence of vaporized cannabis only demonstrated problems weaving within the lane.
Drivers with blood concentrations of 13.1 ug/L THC, or delta-9-tetrahydrocannabinol, the active ingredient in marijuana, showed increased weaving that was similar to those with a .08 breath alcohol concentration, the legal limit in most states. The legal limit for THC in Washington and Colorado is 5 ug/L, the same amount other states have considered.”

As expected, there was impairment in all areas when alcohol and cannabis were mixed. However cannabis itself, when taken in moderate amounts, seems to trigger no considerable driving problems.

In reality, some would argue that it makes them drive safer or slower.

The research study's findings further light up that alcohol is a lot more harmful drug than cannabis, and in some way the previous is legal while the latter is not.
With cannabis being legalized across the nation, police will be getting their "rules and regulations" in location for the driving masses. They ought to be based upon science and not Reefer Insanity mentalities.
Another vital finding should discourage any efforts to deploy immediate roadside tests for THC-blood levels.

“The study also found that analyzing a driver’s oral fluids can detect recent use of marijuana but is not a reliable measure of impairment.

“Everyone wants a Breathalyzer which works for alcohol because alcohol is metabolized in the lungs,” says Andrew Spurgin, a postdoctoral research fellow with the UI College of Pharmacy. “But for cannabis this isn’t as simple due to THC’s metabolic and chemical properties.”
