Looking at the results from this study we can say cannabis makes stuff all difference with driving a motor vehicle.

CBD in Cannabis Does Not Hinder Driving, Shows Study These findings may help create specific drug-driving laws and help manage medical cannabis in general. A new study led by scientists at the University of Sydney, Australia, shows that a medically active component of cannabis, cannabidiol (CBD), does not impair drivers and only moderate THC effects last a few hours. These findings may help create specific drug-driving laws and help manage medical cannabis in general. The study was published today in the Journal of the American Medical Association. https://interestingengineering.com/cbd-in-cannabis-does-not-hinder-driving-shows-study

Effect of Cannabidiol and Δ9-Tetrahydrocannabinol on Driving Performance A Randomized Clinical Trial Question-  What is the magnitude and duration of driving impairment following vaporization of cannabis containing varying concentrations of Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD)? Main Outcomes and Measures-  The primary end point was standard deviation of lateral position (SDLP; a measure of lane weaving) during 100 km, on-road driving tests that commenced at 40 minutes and 240 minutes after cannabis consumption. At a calibrated blood alcohol concentration (BAC) of 0.02%, SDLP was increased relative to placebo by 1.12 cm, and at a calibrated BAC of 0.05%, SDLP was increased relative to placebo by 2.4 cm. Results-  Among 26 randomized participants (mean [SD] age, 23.2 [2.6] years; 16 women), 22 (85%) completed all 8 driving tests. At 40 to 100 minutes following consumption, the SDLP was 18.21 cm with CBD-dominant cannabis, 20.59 cm with THC-dominant cannabis, 21.09 cm with THC/CBD-equivalent cannabis, and 18.28 cm with placebo cannabis. SDLP was significantly increased by THC-dominant cannabis (+2.33 cm [95% CI, 0.80 to 3.86]; P < .001) and THC/CBD-equivalent cannabis (+2.83 cm [95% CI, 1.28 to 4.39]; P < .001) but not CBD-dominant cannabis (−0.05 cm [95% CI, −1.49 to 1.39]; P > .99), relative to placebo. At 240 to 300 minutes following consumption, the SDLP was 19.03 cm with CBD-dominant cannabis, 19.88 cm with THC-dominant cannabis, 20.59 cm with THC/CBD-equivalent cannabis, and 19.37 cm with placebo cannabis. The SDLP did not differ significantly in the CBD (−0.34 cm [95% CI, −1.77 to 1.10]; P > .99), THC (0.51 cm [95% CI, −1.01 to 2.02]; P > .99) or THC/CBD (1.22 cm [95% CI, −0.29 to 2.72]; P = .20) conditions, relative to placebo. https://jamanetwork.com/journals/jama/article-abstract/2773562

This study shows at 100 Kph those who are stoned (THC) can keep a car in their lane within 2cm of those taking a placebo.

This study shows those who fear stoned drivers have an irrational fear.

Hey man

Drivers impaired with marijuana tended to drive to Maccas more often.

Stoned Drivers are like very old people who should have given up their licences years ago. Very slow to react, especially through red lights. Sadly, I've been in such cars with such drivers when I was young. Freaked me out and I wasn't even stoned.
Droopy eyes, bloodshot, tired looking in their being 'high' with life. Fixated gaze, too slow to see that kangaroo or moslem woman down behind the steering wheel of a big 4x4 vehicle pull out.

Only after a time period The problem with drug testing on roads is the inability to distinguish between drug use affecting your diving abilty and drug residue

When I've been totally baked, no way I'd drive.

Why Gordo? Are you 'scared' or something? :D ;D
