It has been announced (by health authorities) that smoking will be banned in all public places. The new measures were accepted by citizens with great enthusiasm. It has been requested that the new law is enforced by the government immediately. A campaign has also been organised (by the State) to inform the public about the dangers of smoking, as it has been shown by recent surveys that the majority of lung cancer incidents in our country are caused by smoking. However, protests against these measures are being organised by smokers.
