RT Journal Article SR Electronic T1 Marijuana use and breastfeeding. JF Canadian Family Physician JO Can Fam Physician FD The College of Family Physicians of Canada SP 349 OP 350 VO 51 IS 3 A1 Josephine Djulus A1 Myla Moretti A1 Gideon Koren YR 2005 UL http://www.cfp.ca/content/51/3/349.abstract AB QUESTION: One of my breastfeeding patients is using marijuana to combat chronic pain. Is it safe for her to breastfeed? ANSWER: Lactating mothers should refrain from consuming cannabinoids. Advising mothers to discontinue breastfeeding if they cannot stop using cannabinoids must incorporate the known risks of formula feeding. Cannabinoid exposure through milk has not been shown to increase neonatal risk, but there are no appropriate studies of this. In every case, nursing babies should be closely monitored.
