BANGKOK, Jan. 31 (Xinhua) -- A smoking ban will come into effect at 24 Thailand's most popular beaches across 15 provinces on Feb.1.

According to the regulation promulgated by the Ministry of Natural Resources and Environment, 24 beaches in 15 provinces across the country are declared no-smoking zones. Violators will face fines of up to 100,000 baht (3,226 U.S. dollars) and/or a year in prison.

The ban affects famous beaches including Patong, Koh Khai Nok, Koh Khai Nai (Phuket); Hua Hin, Cha-Am, Khao Takiab (western province of Prachuap Khiri Khan); Pattaya, Jomtien, Bangsaen (eastern province of Chonburi) and Samila (Songkhla city).

The smoking ban regulation came into play last November since it was published on the government website with a 90-day trail. During the trail period, authorities have been putting up "No Smoking" signs written in Thai, English and Chinese at most of these beaches.

According to officials, the regulation aims to reduce marine pollution and bring beaches fresh air. More beaches are expected to be added to the list in the future.
