Most men drink vodka. The women occasionally drink, but they drink a lot less than the men, and they usually drink wine. It’s somewhat common to see people excessively drunk in public, but it’s frowned upon.
Smoking is pervasive in the culture. The men smoke a lot, but women don’t.
There isn’t really “dating” in Uzbek culture. Most marriages are arranged by the parents. Often, the couple doesn’t know each other well before the wedding. They might meet a few times before the wedding with parental supervision. This is more the case in rural vs. urban environments.
In Uzbek culture, most women are submissive and dating would probably get a woman in a lot of trouble with her family.
