Key results

Although some programmes showed promise, especially those that used group counselling and those that combined a variety of approaches, there was no strong evidence that any particular method was effective in helping young people to stop smoking. Trials differed in how they measured whether a person had quit smoking, and many trials did not have enough participants for us to be confident about wider application of the results. Medications such as nicotine replacement and bupropion were not shown to be successful with adolescents, and some adverse events were reported, although these events were generally mild and findings were based on studies with small numbers of participants. Based on these findings we cannot currently identify a programme for helping adolescents to stop smoking that is more successful than trying to stop unaided.

Quality of the evidence

The quality of evidence was low or very low for all of the outcomes in this review. This is because of issues with the quality of some of the studies, the small number of studies and participants for some outcomes, and the differences between the studies.
