Smoking is killing 325,000 people every month worldwide. That's equal to 812 fully laden Jumbo Jets crashing each month with no survivors. That's a shocking statistic but your reason for quitting is probably more personal - you just want to feel better, you want to give up a self destructive habit, you want fresher breath, you want to set a better example for your children, you want more money in your pocket are just some of the good reasons that others have used to help them become smoke-free.
Whatever your motivation to quit is, it's easier with some help. Nicotine Replacement Therapy does make it easier to stop. It's proven to be effective in making the transition from smoker to ex-smoker.
