Chantix is one of those anti-smoking medications which have been recently discovered by Pfizer. Within this short period of time it has become very famous among smokers who want to quit smoking. Most ex-smokers are so satisfied with the drug’s performance that they consider it to be a miraculous gift. However, despite of such positive feedbacks Chantix do have certain side effects and is not recommended to everyone. The most common side effects of Chantix are vomiting, constipation, flatulence, sleeping disturbance, hard stool, nausea and constipation. Another frequent side effect which is not negative at all is lucid dreaming. These dreams are nothing but pleasant fun-filled experiences and are considered by many as quite hilarious and relaxing. The most important benefit of Chantix is that it is very effective in helping people to quit smoking which in turn reduces an individual’s risk of death from heart disease, emphysema, stroke, different types of cancer and chronic bronchitis. Due to smoking every year 170,000 people die from heart diseases, 130,000 people die because of cancer and 50,000 deaths are caused from lung diseases. Looking at the multiple benefits of this drug, the minor side effects can be overruled as they are curable.
