If you don't stop them from driving high, someone else will.

Always plan a safe way home – call a taxi or ride share company, take transit, or have a friend drive you.

Impaired driving laws in Canada have changed. This includes the introduction of three new cannabis and cannabis/alcohol blood concentration limits. The new cannabis limits work the same way as .08 blood concentration does for alcohol. If you are found driving over the limits, you are considered impaired behind the wheel.

Facts to Know:

Cannabis impairs your ability to drive safely

  • Simulated and on-road studies of driving performance found using cannabis increased a driver's likelihood of swerving. Drivers also showed an inability to maintain a safe distance and difficulty controlling speed.
  • A report by the Canadian Centre on Substance Use and Addiction says that cannabis creates performance deficits in many skills required to drive safely, including reaction time, visual function, concentration, short-term memory, and divided attention.
  • The Traffic Injury Research Foundation determined that, in 2013, of Alberta drivers killed in collisions, more than one in four were over the legal limit for alcohol, and one in two had used drugs.

Drug impaired driving has serious consequences

  • Drug impaired driving has serious consequences including criminal charges and provincial sanctions.
  • Driving while impaired by drugs and refusing to comply with a demand for physical sobriety tests or to provide bodily fluid samples is a criminal offence.
  • Drivers who are pulled over on suspicion of drug impairment may be asked to complete a Standardized Field Sobriety Test, which checks for divided attention impairment. This test gives an officer reasonable and probable grounds to then ask for a drug recognition investigation.

Albertans are charged with drug impaired driving each year

  • On average, 6,000 people were convicted of impaired driving in Alberta each year for the last five years.
  • In 2018, 40% of all 24 hour licence suspensions in Alberta were due to drugged driving.
  • Law enforcement agencies have been detecting and convicting drug impaired driving since 1925.
