Marijuana's main mind-altering ingredient was detected in nursing mothers' breast milk in a small study that comes amid evidence that more U. Experts say the ingredient, THC, has chemical properties that could allow it to disrupt brain development and potentially cause harm, although solid evidence of that is lacking. The new study involved 50 nursing mothers who were using pot and provided breast milk samples to researchers at the University of California, San Diego.

NCBI Bookshelf. The main psychoactive component of cannabis, tetrahydrocannabinol THCis excreted into breastmilk in small quantities. The duration of detection of THC in milk has ranged from 6 days to greater than 6 weeks in various studies.
Researchers took samples of breast milk from eight anonymous test subjects who regularly used cannabis, and tested the milk for the presence of deltatetrahydrocannabinol THC and its metabolites. The milk was tested 20 minutes after the study subjects smoked marijuana and then at one, two, and four hours post-use. THC levels were highest at one hour after study subjects smoked cannabis.
Using marijuana while breastfeeding can allow harmful chemicals to pass from the mother to the infant through breast milk or secondhand smoke exposure. To limit potential risk to the infant, breastfeeding mothers who use marijuana should be encouraged to abstain from or significantly reduce marijuana use. Data are insufficient to say yes or no.

Marijuana is more widely available than ever, but what does it do to babies? Tetrahydrocannabinol, or THC, the psychoactive ingredient in marijuana that gets people high, can be detected in breast milk up to six days after use of the drug, according to a study published on Monday by the journal Pediatrics. The study found that tetrahydrocannabinol was detectable in 63 percent of 54 samples of breast milk from women who said they had used marijuana before pumping.
Maternal judgment may be impaired. Any secondhand smoke the baby is exposed to increases the amount of the drug your baby receives. Also, because street drugs are rarely pure, marijuana may be laced with other drugs or substances that can also be harmful to the breastfeeding baby.
As marijuana cannabis gains legal status and cultural acceptance state by state, important questions about who should be using the drug are becoming more pressing. The American Academy of Pediatrics AAP is officially recommending that pediatricians advise women to abstain from marijuana use during pregnancy and breastfeeding. Their recommendations are based on a clinical report reviewing the small but concerning body of research suggesting that this practice could potentially interfere with the healthy growth and development of the fetus, infant, or child. More on that in a bit.
