Puffing cigarette was considered to be cool and trendy at a time and nonsmokers were thought to be immature or uncool.

But now, these ads are banned, after; smoking was proved to be the nation's leading cause of preventable death.
The statistics of smoking are always shocking; in spite of the knowledge that smoking is closely related to cancer, more than one quarter of the population in the world still smokes. Studies reveal that more than 10,000 children are taking their very first puff each day and around ten billion cigarettes are sold in a minute around the world. These statistics shows that tobacco is one of the most profit making industries and we are making it richer each minute.

About 90% of lung cancer, 75% of chronic bronchitis and emphysema and 25% of ischemic heart are found to be associated with smoking.
