This Special Collection includes Cochrane Reviews on the following topics: medication; behavioural support; and gradual quitting. Interventions that mimic the act of smoking, notably e-cigarettes, have been excluded from this collection as the risks associated with their use in relation to the current pandemic are not clear. Cochrane Tobacco Addiction are working to remain up to date on all the relevant information, to provide support to people attempting to stop smoking during this difficult time.
