^aFrequencies may not sum to N=103 due to missing values. One patient did not report her education level, one patient did not report his employment status, and one patient did not report his marital status. Four patients did not report their grams of marijuana use per day and three patients did not report their years of regular marijuana use. Percentages may not add up to 100 due to rounding.
