Some 55 percent of the poll's respondents admitted to buying vodka at least once a month, and 49 percent said they drank it at least that often, the ROMIR opinion research center said, adding that 14 percent drank once a week or even more frequently.
Vodka consumption also seemed to increase with age, as people aged between 18 and 35 generally bought vodka once a month at best, while Russians aged 35 to 55 were more apt to buy it on a weekly basis.
Earlier this year, Russia's consumer protection agency said that the country's average annual alcohol consumption has reached 15 litres per person, nearly tripling the 1990 average of 5.4 litres.
While Russians still drink a lot of vodka, they are consuming ever more beer and other drinks with low alcohol levels. The production of such drinks increased six-fold between 1998 and 2006, and sales were multiplied by three over the same period.
