Should I dump my milk after smoking weed?

No judgement please because I already know. Last night I did end up smoking weed for the first time in a year and a half. It wasn’t a lot and it was just the one time. I don’t plan on smoking more unless I decide to quit nursing. My son is 10 months and I was thinking about quitting breastfeeding soon anyway (having a hard time deciding). This morning I go to pump since I didn’t have my son last night and I pumped 8 oz that I’m having a hard time dumping out but I will if it’s best. Should I be pumping and dumping for a while? Would I still be okay to just breastfeeding since it was the one time?
