Imagine if you had to tell a family that their child was never coming home again...because a driver had a few too many drinks and they were too lazy to get a taxi? How would you feel if it was your child? Your brother, your parent, your best friend? Now imagine that you're the one who had a few drinks and thought...Home isn't too far. I'll make it without getting busted. While on the back streets worrying if the booze bus will catch you, you hit someone. How do you live with that for the rest of your life?Dec 2, 2020
Cannabidiol (CBD) – a key component of medicinal cannabis products – does not impair driving, a landmark study led by Australian researchers has found.
Researchers found that a moderate amount of THC produces mild driving impairment, but the effects wear off after four hours.
The study is the first to show the lack of CBD effects on driving and to provide a clear indication of the duration of THC impairment.
The study was led by researchers from the Lambert Initiative for Cannabinoid Therapeutics at the University of Sydney and conducted at Maastricht University in the Netherlands.
Previous studies have looked at the effects of cannabis on driving, but they have not “precisely quantified the duration of impairment” from THC, and most have overlooked CBD entirely.
“This is the first study to illustrate the lack of CBD effects on driving and to also provide a clear indication of the duration of THC impairment,” Professor McGregor said.
He said the results “should reassure people using CBD-only products that they are most likely safe to drive, while helping patients using THC-dominant products to understand the duration of impairment”. For complete article New Daily.Com.au
But this new single study is at odds of other research ...
Those findings don’t gel with prior research. Asbridge et al (2012) completed a systematic review and concluded that cannabis contributed to vehicle collision risk. In their review of trends in states and nations that have legalised, Fischer et al (2020) note that cannabis-related road fatalities show a tend to have increased.
