For my part I am an occasional smoker (1 package per month) it's pretty little.
In fact I smoke a cigarette after lunch when I'm at work. It's my little moment of relaxation.
Otherwise I sometimes drink mojito terraces bistros especially during the summer.
And I happen to be drunkenness two or three times a year. (birthday, new year, victory of the France football team ...)
It remains quite exceptional.
So, since I'm not a saint myself,I would not allow myself to judge my partner.
But if I find that his consumption (tobacco or alcohol) exceeds the festive framework I will try to encourage him to reduce his consumption in a protective feeling.
Otherwise, like Angelina I will be very angry if a pregnant woman smoked or drank because in this case it no longer corresponds to her individual freedom. (It's even criminal for the child)
So in general I will not be more demanding with my partner than I could be with myself.
