Past-year anxiety disorders symptoms include any symptoms for panic disorder, generalized anxiety disorder and obsessive-compulsive disorder during the year prior to assessment based on the CDISC-IV. Past-year mood disorders symptoms include any symptoms for major depressive episode and maniac episode during the year prior to assessment based on the CDISC-IV. Past-year externalizing disorders symptoms include symptoms for attention deficit disorder, oppositional defiant disorder, and conduct disorder during the year prior to assessment based on the CDISC-IV.
Bold indicates significant p-values.

Odds Ratios (OR) represent relative risk ratios of relative odds.
Adjusted Odds Ratios (AOR), adjusted models include all covariates in the table plus the variables sex, centered age2, centered age of cannabis use onset2, WRAT-4 standardized reading score, amount of alcohol use in the lifetime, amount of tobacco use in the lifetime, and number of days since last cannabis use.
