Ok, I'll play for awhile. Who signed the permission slip for the unlikely field trip to mystery prison. You can smell pot in your bedroom because your bedroom is over hers. So do you live with Dad or Mom? If you live with Dad, you can't smell your Mom's weed.
I think you're jerking people around on this forum. However, if this is actually your living condition you have several avenues, talk to the parent who is actually smoking weed and ask them to stop, talk to your school counselor who will either call Child Protective Services, or the counselor will ask your parents to come in for a chat. You can always call the police, and if the weed smoker is stoned, the police will call Child Protective Services and they will remove you and your siblings from the home. Again if you're in a neglected state, foster care might be your best bet.
If you're just posting a fake situation to get people stirred up, that's not a nice thing to do.
