I have a friend who is twenty seven weeks pregnant shes done herione during the pregnancy and meth once what are the chances of these drugs showing up?

Wrong question: Forgive my frankness. If you're really her friend, you need to ask, "What can I do to help my friend stop doing these drugs, so that she can be a decent parent?" The BEST thing that can happen is that her drug abuse will be detected, Baby put someplace safe away from a drug-abusing mother, and your friend getting clean. I can't help her, but perhaps you can. Please give it a try. Best wishes.
