Hello, I m 22 weeks pregnant and I smoked weed through out most of my pregnancy (so far). I recently quit a few days ago. So I have a few questions. Since I m done smoking it, should it be in my baby s system once she is born? I ve heard that weed stays in the placenta, doesn t matter how much you smoke during pregnancy, is that true? If not, how long? I also heard to drink cranberry juice with a vitamin b12 supplement and it will help THC get out of blood system? Yes, I know its not right to smoke weed while being pregnant but it was the only thing that would help me with getting morning sickness (which seemed to be anytime sickness instead). Thank you in advance for your help!(: Thanks in advance.
