What would you do?

So my husband and his friends were hanging out outside drinking/chatting

And my kids and i were inside . They’re sleeping and I’m up just doing my nightly workout. And i hear sniffing/snorting or whatever u call it. And i go to the window to be nosy and hear them talking about coke. My husband says he doesn’t want any but then changes his mind saying i want some . I’m livid af

I go outside and say wtf are u doing come inside . He goes in and says he hasn’t done anything .i go back outside & tell his older brother/friends , I don’t want him doing shit w/ you guys cause i promise I’ll leave w/ the kids rn! And everyone leaves

I’m just so aggravated bc i feel disrespected... in my own home, my kids are sleeping. Like wtf . I don’t want no one getting hurt... like I’ve heard stories where people have overdosed off of that... idk what to do
