I want to smoke weed inside my parents' house
Why would you want to smoke weed inside?
Because my parents won't know they wouldn't smell a thing.
You shouldn't smoke weed in your parents' house if that is something they forbid. If you constantly disregard their rules, they won't want you living with them. Life will be hard for you if they kick you out.
I think it will be worth it if I get to smoke weed.
I think you should think this through, because a temporary high is not better than having a place to live. There are lots of places these days where you can smoke, so you should just obey your parents' rules and smoke elsewhere.
