Consuming the CBD in cannabis doesn’t make you a worse driver: study – Driving

Consuming CBD does not impair driving performance, and THC only provides mild impairment for up to four hours, according to new research revealed early December.

The revelations are drawn from a study conducted by the Lambert Initiative for Cannabinoid Therapeutics at the University of Sydney, Australia; in concert with Maastricht University in the Netherlands.

Researchers there staged multiple driving experiments to test the effects of four different types of weed on driving ability, reports The Growth Op.

The types included strains in which THC was most prevalent (and consumed in doses high enough to cause intoxication); another with mostly CBD; a third with both THC and CBD; and a placebo pot, used as a control.

The test consisted of inhaling vapourized cannabis, then driving 100 km on public highways in a dual-control car with a driving instructor. The driving test would be performed 40 minutes after consumption, and then also four hours after consumption.

To evaluate participants’ driving ability, researchers recorded the standard deviation of vehicle position (called “SDLP”) — it measures lane weaving, swerving, and over-correcting.

“The SDLP following vaporized THC-dominant and THC/CBD-equivalent cannabis compared with placebo was significantly greater at 40 to 100 minutes, but not 240 to 300 minutes after vaporization,” the study’s authors wrote, adding “there were no significant differences between CBD-dominant cannabis and placebo.”

This is great news for those who suffer from epilepsy, anxiety, chronic pain, and addictions, and are considering using CBD for treatment. Health Canada advises against consuming weed and driving.
