Assessment of genetic variation as a predictor of smoking cessation succes: A review

of pharmacotherapy, especially when they have a different mechanism-ofaction. Conclusion Much progress has been made in unravelling the effects of genetic variants on smoking behaviour and smoking cessation treatment, but much research still remains to be done and prospective trials should be set up to fully confirm the effect of the variants before genetically tailored smoking cessation therapy can be implemented in standard clinical practice.
