A survey of drinkers in Canada by researchers at the universities of Montreal and Western Ontario has found that regularly drinking even small amounts can lead to binge drinking. The study found that regular drinking increased tolerance leading to people drinking more when they went out socialising. By contrast the study found that those people who rarely drink did not consume more than a couple of drinks on a night out. The study surveyed 10,466 men and women about their alcohol consumption over the last year.
