No safe cannabis impairment for driving

Government won't say how long after cannabis consumption you can drive, but McGill study says impairment lingers even after 5 hours

There is no safe level of impairment for driving, according to the Canadian government, and a new McGill study found young people still struggled to make smart driving decisions five hours after marijuana consumption.

Need guidance on how much cannabis you can consume before driving or how long you have to wait after using to get behind the wheel?

You won’t get it from the Canadian government.

That’s because individual experience varies with the quality, method of consumption (i.e. smoke, inhale or ingested), variety of cannabis and its THC levels.

Instead, the government is giving a simple message: Don’t take a chance — don’t drive high.

The concern is cannabis consumption can affect reaction time, concentration and ability to make decisions quickly or handle unexpected events.

Some additional research has been done by McGill University, funded by the Canadian Automobile Association and released this week, that found that even five hours after consumption, driving skills can be affected.

The trial examined the impact of cannabis on the driving ability of 18- to 24-year-old occasional pot users and was done because polling has found that one in five young Canadians believe they are as good or better drivers stoned as they are sober.
