Smoking in the Restrooms

I hate having to use the school's restrooms.It smells so bad.The school might suppose to be "smoke-free" but its not.I don't understand why people would even want to smoke,let alone be stupid enough to do it at school.I think ways to control it would be to have the teachers that stand outside the restrooms to actually go into the restroom.Stand in there!Hello,ever think nobody would smoke if a teacher's in there.Also,I think a smoke detector should be put in the restrooms.I think if some stands were taken,all this smokin would be taken care of.
