ONCB secretary-general Permpong Chaowalit yesterday said officials had recently discussed the measures with their Nigerian counterparts.
The move stemmed from the report, which stated Nigerian drug dealers were passing themselves off as respectable tourists and businessmen, athletes and students.
Some even married Thais to get residency and make it easier to smuggle drugs such as ice, cocaine and ecstasy into the country for distribution here, he said.
They also routinely hired Thais, South Koreans and Chinese to smuggle drugs for distribution in other countries, Permpong said.
He said an increasing number of Nigerians were being arrested for drug trafficking in Thailand, with about 100 currently in jail here.
