Neighbors who smoke were proposed to be fined a ruble. According to the law, smoking in elevators, entrances and other common areas of high-rise buildings is strictly prohibited - violators face a fine of 500 to 1,500 rubles. Regarding your balconies or apartments, there is no direct prohibition, but if the smoke bothers your neighbors, they have the right to demand moral compensation. If talking doesn't help, you can document the violation in a photo or video, collect witness statements, and contact the local police or court.
