Starting next month, Thailand will enforce a smoking ban on 20 of its most popular tourist beaches, including hotspots like Phuket, Koh Samui, and Pattaya. Violators risk up to a year in prison or a fine of 100,000 baht ($3,000; £2,280). The move follows alarming findings by the Department of Marine and Coastal Resources (DMCR), which reported that cigarette butts accounted for a third of all beach litter.
