THC in breast milk: I haven't found any precise studies of this. But, please know that cannabis is harmful to babies' development and thc (active ingredient) is stored in fat. Your breast milk is therefore a prime place for it to go, possibly for a long time. This means that once you smoke, your breast milk would be dosing your baby with thc regularly. Not a good idea.

THC: "The duration of detection of THC in milk has ranged from 6 days to greater than 6 weeks in various studies." REF: https://www.ncbi.nlm.nih.gov/books/NBK501587/
