Input: Throw away account just.. cuz. Context: we all live with my parents because they have a duplex, and while we build another addition for my husband and I, we're staying in the other "apartment" with my sister, her husband and kids, me, my husband and his son. I'm also pregnant.

That being said, my sister's husband has a habit with doing drugs. He's been in rehab and has  already been dealt with my mom once for doing it under her roof. 

Today, my boyfriend was fixing a hole in the fence my dogs had dug when he found a needle 15 feet from their back bedroom door. It wasn't there a few days ago because we had to fill another hole my dog dug (she's a heathen I know but I love her) and there definitely wasn't a needle there. My dogs get into our trash when they get out sometimes, and it's possible they drug it up or something. None of us, nor my neighbors have any medical conditions requiring said needle. My boyfriend has dealt with drugs before and he says it's for sure used for drugs. 

So I'm stuck. My mom will test him if I tell her, and if it's positive he'll get kicked out. But he's awful when he's on drugs, as he's being now. Aggressive, complains about everything, fucks with our stuff and threatens to kill/harm my animals. My sister may be a shitty person and subject her kids to a meth head shiteater, but I don't want my kids anywhere near it. So, WIBTA for showing my mom the needle?
