Smoking cessation programmes in which groups of smokers have the opportunity to learn behavioural techniques and benefit from mutual support for quitting are widely available. The aim of this review is to determine the effectiveness of smoking cessation programmes delivered in a group format, for helping smokers achieve long-term smoking cessation. ⋯ There is reasonable evidence that groups are better than self-help, and other less intensive interventions. There is not enough evidence on their effectiveness compared to intensive individual counselling. From the point of view of the consumer who is motivated to make a quit attempt it is probably worth joining a group if one is available--it will increase the likelihood of quitting. From the public health perspective, groups are unlikely to make a substantial impact because of the low uptake.
