I am 34 weeks pregnant and have been clean of marijuana for 32 days. how much longer do you think it will take to get clean urine. 5'3" 180lbs?

Baby won't be: If I have reason to drug test your newborn I can find any drug exposure back to about 20 wks. Your pee would be clean, but that is not where I look. If you are on the Child & Family Services watch list,have suspicious visitors or other factors that raise concerns it will be found. You need to be up front with your doc so they can help you & baby.

Likely: Most chronic users will test negative after 30 days. Long term heavy, obese, users may test positive longer. Wish you good health and a healthy baby!
