1 in 3 cigarettes smoked in Hong Kong are illegal, controversial study finds
Disputed report funded by tobacco industry giant claims contraband cigarettes cost the city billions in lost tax revenue last year

About a third of all cigarettes smoked in Hong Kong are illegal and the city is losing out on billions in tax revenue as a result.

The study has been disputed by the government and anti-smoking groups.
The report, funded by tobacco giant Philip Morris, was published by the UK-based research institute Oxford Economics and the International Tax and Investment Centre, a lobbying group.
It says Hong Kong lost HK$3.3 billion in potential tax revenue last year as a result of an estimated 1.8 billion illegal cigarettes smoked.
As part of the study, about 10,000 empty cigarette packets were collected across the city last year. Based on their markings, the packs were then classified as either legal domestic, duty-free, counterfeit or illegal imports.
Overall estimates of the number of illegal cigarettes smoked were then derived from the sample collected. Packets left by tourists were not counted, the study said.
