ONCB secretary-general Pongsapat Pongcharoen said tough checks were being carried out on the border between Thailand and Myanmar (21 points), Laos (47), Cambodia (16) and Malaysia (9). Drug dealers were known to have taken opportunities presented by the New Year period to bring in the drugs into Thailand in the past.
They also used many methods, including personal vehicles and public transport such as trains, buses and aircraft, so another 34 checkpoints were also being set up on the routes to Bangkok and its vicinity, where drugs are often kept before being distributed to dealers.
Mail was also being inspected thoroughly to prevent the shipping of illegal products.
Pol Gen Pongsapat said the operation began on Dec 25 and will continue until mid-January.
