If you have been prescribed the drug Champix to help you quit smoking then you might want to consider alternatives. According to this article the drug can increase the risk of heart attacks and strokes. It seems that smokers using the drug are twice as likely to be taken to hospital with heart problems as those who took a dummy pill. Many of those affected also had no underlying cardiac problems when they had started taking the drug. The drug which has been prescribed one million times in the UK last year, helps to dull cravings for nicotine and take away the enjoyment of having a cigarette.
