Vapor barrier for doubled ceiling

I'm considering installing 1/2" firring strips and stapling textured ceiling panels over the existing drywall ceiling through out the house. Some of the attic has blown fiberglass over kraft backed batts, but most is just blown fiberglass with no vapor barrier. I've read that paint is considered a good enough vapor barrier for a ceiling.

Should I install a 6 mil poly barrier? If so, should it be between the firring and new ceiling panels or the firring and old drywall? Is there any concern with installing a doubled ceiling like this in a high humidity area, like a bathroom or laundry?

I'm located in East Tennessee.

Thanks,
Barry

Ceiling tiles should not be used in a bath unless you have very good ventilation.

The drywall in the bath is pretty good. I'll avoid ceiling tiles there. What about the vapor barrier elsewhere?

Thanks,
Barry
