The Season All does (2nd ingredient on the list), The Cherry does not, The Sweet and Spicey does not, The Peppered Cow does, Spicy Apple does not, Sweet seduction does not, and the Pecan doers not. (From Big Poppa's website which lists the ingredients).
So the savory rubs do, but the "flavored/sweet" ones don't.
