1
The p-values are from weight adjusted Chi-square tests comparing those who used cannabis since diagnosis and those who have not.
2
Analyses were conducted with sex (assigned at birth) and gender identity. Results were unchanged and sex was retained.
3
When comparing rates of cannabis use between Black/African-American and White patients only, the difference was significant (p=0.04).
