In all the Cigarette Packets warning is given by printed - SMOKING IS INJURIOUS TO HEALTH i.e. not to smoke for its bad side effect. It causes different types of diseases specially Cancer. In some places it is also written SMOKING PROHIBITED that means not to smoke in those places which may be harmful.
The packaging is beautiful which attracts the smoker.
I do not suggest to take FOUR SQUARE or any type of Cigarette knowing that it may harm us. So do not try smoking.
