From 1 January 2009, all duty-paid cigarettes sold in Singapore will be marked with the letters "SDPC" to distinguish them from contraband cigarettes. The letters "SDPC" stand for Singapore Duty-Paid Cigarette, and it is proof that the cigarette is legal.

It'll be interesting to see what happens to the illegal cigarettes peddlers in Singapore. What will be even more interesting is to watch my friends curse and swear! Fun times are ahead!
