11 studies reported the number of participants who reported adverse events or serious adverse events during the prequit period, and 7 studies reported prequit withdrawal symptoms. For serious adverse events, either none were reported or rates were low and well‐balanced between trial arms. Adverse events were measured in studies where nicotine replacement therapy was used prequit and appeared to be those usually attributed to these medications. Data on withdrawal and craving were sparse and conclusions varied making it impossible to draw conclusions. No studies reported adverse effects of behavioural support, however. |
