Moderate‐certainty evidence shows that more people probably quit smoking using nicotine ECs compared with other interventions, with no concomitant increase in medium‐term adverse events, but the proportion of people quitting may be very low for all interventions (on average, 167 and 68 per 1000 people with nicotine ECs vs 99 and 40 per 1000 people with nicotine replacement therapy and nicotine‐free ECs, respectively). Evidence for nicotine‐containing ECs versus behavioral support is very uncertain.
