There are 17 cannabis-related impaired driving investigations underway in Edmonton this year, about the same rate that resulted in 38 suspected cannabis impaired driving investigations in 2018. Between November and February, seven impaired driving charges related to cannabis were laid under the Criminal Code, compared with 596 charges for impaired driving by alcohol, Cpl.
