Descriptive data were analyzed and for several variables separated by year to include age, race, ethnicity (Table 1 ); and type of admission and insurance (Table 2 ) for mothers; and birthweight, gestational age, and length of stay for newborns (Table 3 ). Cochran-Armitage chi-square testing was completed to test for trends in categorical data proportions and evaluate the proportions of screened patients who tested positive for drugs, including medical or recreational cannabis, since the data appeared to indicate an increasing trend in these proportions over the years (from 2013 to 2017).
