A Buddhist temple in central Thailand has been left without monks after all its holy men failed drug tests and were defrocked, a local official said on Tuesday.

Four monks, including an abbot, at a temple in Phetchabun province’s Bung Sam Phan district, tested positive for methamphetamine on Monday, district official Boonlert Thintapthai told Agence France-Presse (AFP).

The monks have been sent to a health clinic to undergo drug rehabilitation, the official said.

“The temple is now empty of monks and nearby villagers are concerned they cannot do any meritmaking,” he said.

Merit-making involves worshippers donating food to monks as a good deed.

Boonlert said more monks would be sent to the temple to allow villagers to fulfill their religious obligations.

Thailand is a major transit country for methamphetamine flooding in from Myanmar’s troubled Shan state via Laos, according to the United Nations Office on Drugs and Crime.

On the street, pills sell for less than 20 baht (about 50 US cents).

Authorities across Southeast Asia have made record meth seizures in recent years.
