The question to ask is, why is the rest of us not addicted? Most of us drank at some point, and we aren’t. What’s the difference between people who get addicted, and those that dont
Maybe (but you can still buy booze illegally after 11pm - or at bars). I think it's more or less greatly improved economic conditions and improving quality of life. The 1990s and early 2000s in Russia (Belarus & Ukraine as well) were seriously dire. I was surprised by how many people didn't drink in my travels there. A good movie to check out on that time period is "Brother" (Brat).
