Marijuana Smoking Associated With Minimal Changes In Driving Performance, Study Finds
FRIDAY, 28 MAY 2010 13:00 PRESS RELEASE AUTOMOTIVE


Hartford, CT—(ENEWSPF)—May 28, 2010 Subjects exhibit virtually identical psychomotor skills on a battery of driving simulator tests prior to and shortly after smoking marijuana, according to clinical trial data published in the March issue of the Journal of Psychoactive Drugs.

Investigators from Hartford Hospital in Connecticut and the University of Iowa Carver College of Medicine assessed the simulated driving performance of 85 subjects in a double-blind, placebo controlled trial. Volunteers responded to various simulated events associated with automobile crash risk — such as avoiding a driver who was entering an intersection illegally, deciding to stop or go through a changing traffic light, responding to the presence of emergency vehicles, avoiding colliding with a dog who entered into traffic, and maintaining safe driving during a secondary (in-the-car) auditory distraction. Subjects performed the tests sober and then again 30 minutes after smoking a single marijuana cigarette containing either 2.9 percent THC or zero THC (placebo).

Investigators reported that volunteers performed virtually the same after smoking cannabis as they did sober and/or after consuming a placebo. "No differences were found during the baseline driving segment (and the) collision avoidance scenarios," authors reported.

Investigators did note, "Participants receiving active marijuana decreased their speed more so than those receiving placebo cigarette during (the) distracted section of the drive." Authors hypothesized that subjects' reduction in speed on this task suggested that they may have been compensating for perceived impairment. "o other changes in driving performance were found," researchers concluded...

And here you go on some other research about cannabis, not limited to driving effects:


Scientists have actually known this since 1974, when the feds shut down a study at the University of Virginia when it showed conclusively that cannabinoids kill cancer.
