A friend of mine tested positive for marijuana at 14 weeks during her pregnancy and they told her that they may test the baby when it is born because of this. She said she used once at about 21-23 weeks and tested negative at her 28 weeks appointment but is worried the babies meconium will still test positive. What is the likelihood that this will happen even though she only used once?
The chance that the babies meconium will test positive is very low. Hopefully she doesn't delivery anywhere close to 21 weeks and the marijuana will be out of her system by the time she delivers. Marijuana takes about 30 days to get out of the system. Good luck!
