Scientists are warning that the smoking ban should be extended to outside bars and pubs, to help ease the number of social smokers.
The restriction has led to a decline in the number of people smoking but indulging socially has risen amongst young adults.
Social smokers claimed that they 'spiritually' distance themselves from full-time smokers.
Those aged between 19 and 25 also added that they usually smoked when they had been drinking, saying the two normally 'going hand in hand'.
Professor Janet Hoek, of the University of Otago in New Zealand, explains: "Introducing smoke-free outdoors bars could reduce social smoking by removing cues that stimulate this behavios and changing the environment that facilitates it."
