My friend is too scared to ask her doctor or her family this question and she talks to me a lot about it so I have been surfing the internet to try finding an answer. Sometimes she abuses Adderall. She's wondering how long it would stay in her breastmilk? When she does take "speed" she doesn't nurse for 24 hours. If she takes it at 9am,she wont nurse again until 9 am the next day. She does pump and dump and continue to to pump every 3 hours to continue her milk supply. She has frozen milk so she uses this while shes not nursing. I have found out online that the peak of Adderall is 2 hours after you take it. Does anyone know how long exactly it stays in breastmilk and is 24 hours a good amount of time to give it to pass through?
