Imo, as someone living in a muslim country with alcohol sales ban on muslim only, there’s nothing similar to this. For one, if the law isn’t being amended later on, the sales ban will only and ever only imposed on muslim, prohibiting them from ever purchasing alcoholic drink. This has been a thing since the begining of Islam. What different from the generation ban is there’s in no point in time alcohol would be prohibited to anyone. The generation ban on tobacco sales however will adjust the age of smoking up by one year, every year, automatically without amending the law, so by the time the last person born after a certain year dies the prohibition will only then take effect for everyone. This is what i mean it’s new-ish, because it’s not a hard blanket ban like everything we used to see, but a soft ban that slowly take effect in a time span of a few decades.

As for it being effective or not, if we compared to the alcoholic drinks ban for muslim, does it stop muslim from drinking? No. But does it significantly decrease it? Yes. It also mean it’s significantly harder for muslim to be addicted to alcohol exactly because it’s harder to obtain and consume it, they can’t just walk into a store and get it, they have to get from other source.
