Does Nicobrevin help people to stop smoking

Nicobrevin is a proprietary product containing quinine, menthyl valerate, camphor and eucalyptus oil marketed as an aid to smoking cessation. No randomised trials with long-term follow-up of smoking status were identified, so there was no evidence to assess efficacy.

Authors' conclusions: 

There is no evidence available from long-term trials that Nicobrevin can aid smoking cessation.
