Using the Severity of Dependence Scale to examine cannabis consumers with impaired control in Canada
Cannabis is one of the most widely used substances in Canada, with more than 4 in 10 Canadians reporting having tried it. The use of cannabis in Canada has been rising for several decades, including after legalization. Some data also show that higher frequency use, such as daily or almost daily use, was more common in 2020 than in the previous two years.

Self-reported concussions in Canada: A cross-sectional study

Traumatic brain injuries (TBIs) are a major public health concern impacting the lives of many Canadians. Between 2002 and 2016, over one-fifth of all injury deaths in Canada were associated with a TBI diagnosis. These injuries also result in approximately 20,000 hospitalizations in Canada each year (this estimate excludes Quebec). Among all types of TBIs, concussions are the most common, accounting for approximately 80% to 95% of such injuries. Often termed as a “mild TBI,” a concussion typically results in a rapid onset of short-lived impairment of neurologic function that resolves spontaneously. Common symptoms include headache, dizziness, nausea, fatigue, and sensitivity to light and sound. Though loss of consciousness may also occur, this outcome is observed in less than 10% of cases.
