Victoria, British Columbia: The use of marijuana alone does not place subjects at a higher risk of experiencing injuries requiring hospitalization, according to case-control data published in the journal Drug and Alcohol Dependence.
Investigators from the United States and Canada assessed the risk of injury in the hours immediately following subjects' use of alcohol or other controlled substances.
Researchers determined that alcohol use within the past six hours significantly increased subjects' likelihood of injury requiring hospitalization while the recent use marijuana alone did not. By contrast, recent use of alcohol and marijuana in combination "marginally" increased injury risk.
The findings are largely consistent with those of previous studies reporting a lack of association between cannabis use injuries requiring an emergency room admission, such as those here, here, here, and here.
