This new regulation was first approved and implemented by the FDA back in 1996 (I urged the FDA to do so back then), but was struck down by the US Supreme Court in 2000 when it ruled that the FDA wasn't authorized by Congress to regulate
tobacco.
Nearly all of the provisions in this new FDA rule have already been implemented by local and state laws and/or by the 1998 Master Settlement Agreement between State AGs and tobacco companies.
So there's really nothing new here, just a press conference in which current FDA officials grandstanding about what was largely achieved a decade ago.
