Somewhere 20 years ago it was possible to buy a counterfeit Vodka and get poisoned. Now it's almost impossible. Each bottle has its own unique QR code in the federal alcohol accounting system. This number can be checked in the official base with a regular mobile phone. Thus, a same bottle can't be sold twice through the store's cashier.
