Hi, I understand your concern. Marijuana smoking in pregnancy affects baby in many ways. It can cause low birth weight babies/ abortions/still births. Baby has low resistance & easily gets various disease like asthama. Brain/intellectual growth of baby is affected- producing behavioral/learning difficulties. - as she has stopped smoking for last 2 months- she may escape legal involvement at delivery- but if she starts smoking again while breast feeding, she herself can be caught by drug in breast milk/ baby will have side effects even after birth. - The best option is to stop smoking Marjunia since planning a child birth- because it s a mother s moral duty to provide a strong body & mind to her own baby! Thanks.
