Brief Answer: urine-upto 10 days, meconium- upto 4 to 5 months Detailed Answer: Hello, I have gone through your query and understand your concern. A mother will test positive for TCH roughly 30 days after exposed, general estimate. But this can be longer or shorter. At birth, depending on maturation and metabolic functioning, some newborns may test positive. I would strongly advise against any further marijuana smoking till delivery. First of all, the fetus is more susceptible to marijuana. Secondly, smoking marijuana can be considered unfit parenting; if testing positive, this could result in legal and custodial problems. Meconium is the earliest infant stool, and begins to form in the womb between weeks 12 and 16 of pregnancy. Meconium screening can detect drug exposure in the last four to five months of pregnancy. But drug testing depends on the hospital and state you live. Some may test meconium and some check urine. Usually THC will be excreted up to 10 days in baby s urine after last use. But meconim may show positive, if you used weed in last five to four months Hope this helps. Please write back for further queries. Wishing you good health.
