Abstract

Objectives: We investigated trends in cannabis-related hospitalizations among youth before and after legalization of recreational cannabis in Canada on October 17, 2018. Methods: We computed rates of cannabis-related hospitalizations and the proportion of substance-related hospitalizations involving cannabis by age and sex in the months before and after legalization in Quebec, Canada. Results: In boys aged 10 to 14 years, cannabis-related hospitalization rates increased from 5.2 per 100,000 one year before legalization [95% confidence interval (CI) 2.9–9.3] to 9.5 per 100,000 after legalization (95% CI 6.2–14.6), although the increase was not statistically significant. Cannabis was reported in 39.3% of substance-related hospitalizations in boys aged 10 to 14 years before legalization, compared with 70.0% after legalization, representing a difference of 30.7% (95% CI 2.8–58.6). There was no increase in cannabis-related hospitalizations among girls or boys aged 15 to 19 years. Conclusions: This study suggests that cannabis legalization in Canada did not increase the risk of short-term cannabis-related hospitalization among girls and older boys. However, legalization may have contributed to an increase in the risk in boys under 15 years. Further data are needed to clarify trends after legalization for younger adolescents.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
