So this just happened minutes ago, I live in a house with 8 people, including a one and a half year old boy who shoves literally everything in his mouth, ex: house phones, spoons, remotes, etc. Just anything that fits in his mouth. My sister lets him roam unsupervised a lot and makes other people watch him or she just leaves him alone for 10 minutes at a time so she can go smoke weed or cigarettes. She had a child outside of marriage and was pregnant while she used heroin, but quit when the baby boy was born so she could live with us and we could help care for the baby boy. Her boyfriend lives with us too under the condition that they both work. She and her boyfriend have smoked for the entire time the baby boy was growing in our house and I have no idea when they started smoking marijuana. We don't know how to handle them smoking pot since it's legal now so we decided to let it go and warned them it's a gateway drug.

Although I'm completely against the use of drugs/tobacco and I know she can choose how to spend her life doing whatever she wants, I just don't want that around her son who isn't capable of leaving the room is she smokes in it and doesn't know better than to not touch the cigarettes. I constantly find rolled joints and cigarettes, both used and unused, on the ground, on her bed (when she asks me to watch him) and on low tables. I tell my parents since they are the owners of the house and they told me not to start conflicts with her, but today I found a whole cigarette on the floor of the room her son plays in and my dad (a total hard ass) saw me pick it up and I brought it to my sister's bf to tell him I found it and it was dangerous. My dad then walked over and started telling him how he's repeatedly said no tobacco in the house and the bf just says it fell off from behind his ear (He perches his cigarettes there like you would a pencil). things go bad and there's arguing. then my sister comes down with her toddler and my dad reminds her about the no tobacco rule. She asks why I'm there and my dad says I'm the one who found the cigarette and I tell her that her son could choke on it or poison himself and she starts yelling we are all ganging up on her. I make her son a bottle of milk because he looks thirsty and I thought that's what she came down here to anyways, so i give it to her and tell her I'm not mad at her and she shoves me away.

I decide to let her cool off so I go upstairs and go to my room and lock the door, it's a habit. 5 minutes later, she's pounding at my door telling me it's my fault all this happened (my dad told her I showed him the cigarette) and that if her son doesn't have a father and leaves her because our dad yelled at her bf on his first day back from a trip, it's all my fault. Am I the Asshole? I don't know what to do

not wanting my sister and her boyfriend to leave cigarettes and joints around my one and a half year old nephew in my parent's house
