Conclusion
For drinking smokers, both meta-analysis indicated that Varenicline
might be a meaningful drug in quitting smoking, while compared with
placebo, the remain drugs do not show obvious superiority in smoking
cessation. At the same time, we should comprehensively evaluate the
safety of these drugs and seek the best dosage. However, based on the
limitations of this study, more large-scale and high-quality randomized
controlled trials are needed to provide evidence to support the
effectiveness and safety of smoking cessation drugs.
