In France, for example, it is traditional for children to have a glass of wine with dinner, some as young as pre-teen (though more like half-a-glass, in those cases).
The alcohol problem that the "developed" world has is more due to binge drinking, which arguably can be tempered by a more realistic attitude. (Might have something to do with the Calvanistic wish for prohibition trying to wrestle with repressed desires for losing sharp focus of the responsiblities of the world. That, and / or the wage-slavery of most people, and what that causes some people to do to others, which drives them to drink to excess to drown out their reality.)
If your example was with a packet of cigarettes, then I would concur with your implication that such parenting is not good.
