Mothers Against Drunk Driving says the guidelines are rough and it comes down to ‘personal responsibility’It may be legal to smoke pot, but driving under the influence of pot could get you in trouble if you’re considered impaired.
However, Mothers Against Drunk Driving (MADD) is worried that the rules are a little fuzzy.
Eric Dumschat, legal counsel for MADD, said the organization can only give guidelines as to how long people need to wait after consuming marijuana.
“At some level it does come down to personal responsibility. There’s no magic number,” said Dumschat. “You need to make that determination for yourself.”
He said the organization has been using the range of four to six hours after consumption, but there’s a lot of “personal variation” in terms of the degree and duration of impairment.
Police will have a number of options for catching people driving under the influence of pot.
One is a standardized sobriety test officers have been using since 2008, said Dumschat. The newer one is a saliva test.
However, the technology is still relatively new and would not be as good as tests for blood alcohol, according to Dumschat, because there hasn’t been as much research put into cannabis as there has been for alcohol.“We suspect that in the coming years, these [tests] will become much more quick, much more accurate, much more cost-efficient,” he said.
For now there have been concerns raised about whether low temperatures would affect the saliva test results or not.
When it comes to preventing impaired drivers from getting behind the wheel in the first place, Dumschat said there needs to be “a lot more education” when it comes to pot.
“There’s this persistent myth, especially among young people … [that] they drive better after they smoke pot,” he said. “That is objectively false.”
He referenced a McGill University study which showed young people who use cannabis and drive are at a greater risk of being in a collision even after five hours have passed.
“The science in this is clear,” said Dumschat. “You can’t drive if you are under the influence of drugs or alcohol.”
