Hi.my friend is 37 weeks pregnant and she has on occasion smoked marijuana (thc) thruout her pregnancy so she could sleep due to severe pelvic pain..she is having csection in a week and s terrified that hospital will test her and baby for thc. She is also afraid the cps will take baby from her. She has no prior record of any use of any sort and she has 2 orher children that she never did that with while pregnant. She just said she just couldn't tolerate pains and sleep depravation. What do u recomend she do and can she flush thc out of her system before delivery? Can cps take baby from her?
