Smoking while breastfeeding

Okay, so I’m not a new mom by any means, but this will be my first time exclusively breastfeeding. I’ve been smoking weed for around 12-13 years consistently. My question is, has anyone breastfed while still continuing marijuana use? I’m just curious if it could harm my child or if any of the thc would be passing through to his body. I do not smoke while he’s awake, and I also pump when finished smoking, and I wait about 2-3 hours before feeding him again. I don’t smoke thattttt often, maybe once or twice a day, if that. I was smoking about 5-6 times a day prior. Any advice anyone has would be greatly appreciated.
