I quit smoking weed at 26wks pregnant. will i be clean before baby is born? also what kind of drug is preformed after delivery? do they test my urine or baby's poop?

I'm glad that you stopped & if you stay off and avoid bringing attention to yourself things may go well. Your system will clear. Baby ? If you get on the watch list put out by child & family services,we look at babies poop.Their poop can retain trace evidence of any drug exposure for several months. If you cheat just once or have heavy 2nd hand exposure it may show up.
