Starting Saturday evening, no alcohol can legally be sold in Thailand, in accordance with the country’s new Referendum Act.

Polling will take place on Sunday, and the act forbids selling or giving away alcohol from 6 P.M.  the night before. The ban will continue until 12 midnight Sunday night.

Violating the 2016 Referendum Act is punishable by up to six months in prison and a 10,000 baht fine.

Sales will be permitted at duty-free stores, but the alcohol cannot be consumed within the country until Monday morning.
