A member asked:

Friend will be tested because of positive drug test for pot at 19 weeks. hasnt touched it since will it show in meconium at birth in 20 weeks?

A doctor has provided 1 answer

Wrong test: Meconium is fetal not maternal. There is no standard lab test for thc metabolites in meconium. A retest of your friend would normally entail a urine test and in that case it will still be positive as thc metabolites can persist for over a month after cessation of pot smoking.
