For those of you mobile chimneys out there, Tobacco has not relented in destroying lives of its users.

A new report from World Health Organisation, WHO says smoking and other tobacco use kills more than seven million people each year.

According to the report released on Tuesday, the organization also warned of the dire environmental impact of tobacco production, distribution and waste.

The UN agency said tougher measures are needed to rein in tobacco use, urging countries to ban smoking in the workplace and indoor public spaces, outlaw marketing of tobacco products and hike cigarette prices.

"Tobacco threatens us all," WHO chief Margaret Chan said in a statement.

"Tobacco exacerbates poverty, reduces economic productivity, contributes to poor household food choices, and pollutes indoor air," she said.

In a report released ahead of World No Tobacco Day on Wednesday, WHO warned that the annual death toll of seven million people had jumped from four million at the turn of the century, making tobacco the world's single biggest cause of preventable death.

And the death toll is expected to keep rising, with WHO bracing for more than one billion deaths this century.

"By 2030, more than 80% of the deaths will occur in developing countries, which have been increasingly targeted by tobacco companies seeking new markets to circumvent tightening regulation in developed nations," the report said.

So, they questions is would your habit kill you?
