I agree with you but I also think it was really unnecessary for her to discuss it. It is a non issue that she is clearly using for PR purposes. Now on the other hand it would have been reasonable for her to confirm her stance on smoking had someone asked since she publicly advocated against it and is now publicly smoking.
Priyanka was asked about it in an interview so she answered. For American media smoking isn’t a big deal, body shaming is.
