Zhao Cuiping, a youth expert, said: "Research conducted over the past decade has shown that young people like scary images, like skulls, much more than pleasant ones like cats and dogs.
"Rebellion, curiosity and craving for stimulation are the character traits of this group. So putting a skull on a pack of cigarettes might well attract a young person to take up smoking."
Zhao was speaking in response to comments made at a lecture last week by an official from the Chinese Center for Disease Control and Prevention.
He said that in line with the WHO's "Framework Convention on Tobacco Control", which China joined in 2006, from January 2009, all cigarette packets must carry one of the "offensive" images and that it must cover at least 30 percent of the surface area. China currently has 350 million smokers.
And according to a report by Ma Jun, a professor at Peking University, the age at which people are taking up smoking is getting younger.
An official with the State Tobacco Monopoly Administration, who asked not to be named, said it was still possible the images might not be used.
