Constituent information on MC products was available for n=22 at 3-month follow-up and n=15 at 6-month follow-up.
At the 3-month follow-up, one of the 15 samples that tested positive for THC metabolites was unable to be processed by Quest Diagnostics (n=14 for these analyses); at the 6-month follow-up, all MC patients who had a positive urine screen had further quantification analyses.
Patients could report multiple routes of administration.
CBD, cannabidiol; IQR, interquartile range; THC, Δ-9-tetrahydrocannabinol.
