Stop smoking marijuana at 22 weeks. i am not a heavy smoker. i only smoke 3 times during whole pregnancy due to sickness .. will it still be in baby system?

If you showed up on a Child & Family services watch list in my state I would be obliged to do some specific tests that could detect such exposure. Baby does carry some evidence for exposures after 12 wks. However, if you don't hang with a crowd that triggers the question of drug use they won't even look.

no, with the amount of marijuana use during your pregnancy it will not affect your baby and it will not be in their system. The amount of marijuana in a patient’s system is dependent on the frequency and amount used.
