Unborn babies don't produce urine. Meth can be detected in their hair, even after they are born.
How Long Does Meth Stay In Unborn Babies Urine?
Good Lord, this is a truly horrible question, you mean you're pregnant and still doing meth, or you've had your baby and you're trying to figure out how long the meth is going to stay in his/her system? For what? Baby having a drug test? Getting adopted? This sounds like a real mess to me.
I'm pregnant and seeing this question sickens me you don't deserve a baby and you should be imprisioned for this
