Consumers snatch cigarettes from shelves as it is every man for himself.
Major supermarkets and mama shops have put up notices saying there are no stock left.
This after Singapore authorities are looking at raising the minimum legal age for buying and using tobacco from 18 to 21.
Proposed changes to the law will be tabled in parliament within a year and the change will be phased in over a few years after the law is passed.
Youths above 18 who are already smokers will not be affected by the change.
One Singaporean, Xio Kah Tor, said: “Tonight I will drink and smoke until don’t recognise house.”
“I will buy a few years’ supply and put in Tupperware to keep them fresh.”
“The law says youths above 18 who are already smokers will not be affected by the change. But how would they know who is already a smoker?”
“Will these smokers be required to carry an identification card? If not, how to identify?”
