Whether it is safe to give a baby breastmilk with THC is a huge debate because there are so few studies and this is a touchy subject. I will not say one way or another whether it is safe or harmful because I don't want to get blasted. However, I will tell you that THC remains in breastmilk for several days after smoking. In fact, if you smoke several times over a few day period, the THC level in breastmilk can be higher than bloodstream levels because it gets concentrated. If you do not want your baby to have THC then you should wait about 3-5 days after a single session and maybe 5-8 days after multiple sessions.

Now you are going to get a bunch of responses from people still in high school.
