Thailand screens Korea-bound workers for drugs

Thailand's Office of the Narcotics Control Board (ONCB) has found one methamphetamine user among 250 Thai workers preparing to leave for jobs in South Korea.

The screening operation, forms part of efforts by Thai and South Korean authorities to keep drug users out of overseas employment schemes. The worker who tested positive has agreed to enter treatment in Bangkok.

One positive result from 250 screenings

The ONCB's Narcotics Suppression Bureau and its Bangkok office carried out urine tests on the prospective workers before their planned departure to South Korea.

One man, identified only as Mr P, tested positive. He is from Kut Chap district in Udon Thani province.

During initial questioning, he admitted using methamphetamine, also known as ya ba, three days before the test. Thai authorities classify the drug as a Type 1 narcotic.

Officials said they spoke with him until he agreed voluntarily to treatment. He was then taken to the District 4 Din Daeng Public Health Service Centre to begin the process.

Drug checks linked to overseas work prospects

The checks are being conducted in cooperation with the Department of Employment under the Labour Ministry and South Korean authorities. The stated aim is to improve confidence in Thai workers and ensure those travelling overseas for work are drug-free and able to enter legally.

The ONCB warned Thai workers planning to work abroad to avoid drugs entirely. It said anyone found with narcotics in their system could have their travel rights suspended immediately and lose their overseas job opportunity, while also facing legal action in Thailand.

Authorities further warned that anyone caught taking drugs abroad, or committing drug offences in the destination country, could face severe local penalties. These may include lengthy prison terms, permanent blacklisting from entering that country, and immediate deportation back to Thailand.

The ONCB said reports involving drugs, labour scams, or requests for treatment advice can be made confidentially through its 24-hour hotline on 1386.
