Main question
Is quitting abruptly more effective than cutting down gradually before quitting?
Main findings
People who quit abruptly were more likely to achieve abstinence than those who reduced gradually first. Both approaches produced some successful quitters.
Limitations
Trials varied in how reduction was defined and supported; participants were treatment-seekers.
