second hand smoke

, I need some reassurance. I'm still breastfeeding and lady night we had people over, baby is at my moms, and some friends lit up and smoked weed in the apartment. I definitely got more than a few puffs of it. I'm nervous that it will make my breastmilk unsafe for my baby to consume. Also I started to read that THC from the weed stays in your fat cells for months. Will second hand pot smoke have any affect on my baby through my breastmilk. I'm so mad at those friends and I need some answers because I'm freaking out!!
