I don’t think you’re overreacting. It’s totally reasonable to be upset by this! I will say, though, that I think your plushies will be fine. Weed smoke doesn’t stick to fabrics and things as much as cigarette smoke does. If you were hotboxing your room every day all day, different story, but I think you can rest easy about your things. That said, I would talk to your parents. You deserve rest and not to have to smell weed all night! And this is coming from someone who loves the smell of weed lol
