Singapore will put special markings on every cigarette sold legally starting next year, Agence France-Presse reports.

As of January 2009, every cigarette on sale will come with "SDPC" (Singapore Duty-Paid Cigarettes) stamped near the filter, Singapore Customs said in a statement released on its website on 11 September.
"All unmarked cigarettes will be deemed to be duty-unpaid and illegal," the statement said.
Anyone caught with an unmarked cigarette will be committing an offence and will face a fine of SGD 500 (EUR 249) for every packet found in their possession. It also added that travellers who bought cigarettes overseas for their own consumption should keep their receipts.
"The availability of cheap duty-unpaid cigarettes will hamper our national effort to discourage smoking," said Fong Yong Kian, director-general of Singapore Customs. "The marking will serve as deterrence against the peddling and buying of contraband cigarettes and help our officers in the enforcement efforts," he added.
In 2007, 32.9 million packets were seized resulting in SGD 32.9 million in lost revenues, the Straits Times said.
