Abstract
Background
Urine drug screening is a frequently used method to detect the abuse of psychoactive substances. Daily heavy cannabis users can have positive urinary cannabinoid metabolites up to 30 days following abstinence.Case presentation
Consumer is a 29-year-old male with BMI of 54.64 Kg/m2 and a history of long-term cannabis dependence. He was diagnosed to have co morbid mental illness of schizophrenia. His-urinary drug screen was positive for cannabinoid metabolites 102 days following abstinence. He had neither access nor other objective evidence of cannabis use during that period. Confirmatory testing using GC/MS method confirmed the dropping concentration of cannabinoid metabolites over 102 days and confirmed the same with cannabinoid creatinine ratio.Conclusion
This is the longest detection period of urinary cannabinoid metabolites following abstinence of cannabis use. Differentiating active recent cannabis use from long term excretion of previously used cannabis is vital in making legal and treatment decisions.PDF HERE

tldr: the guy was using a gram a day and was morbidly obese (440 lbs/ 6'2"), so his body had stored a lot of THC in his fat. But even under supervision, he tested positive for 102 days
