Trying to kick the habit? Harvard and University of Boston researchers say things like nicotine patches and nicotine gum, are expensive, and not that effective.

The study was done over a six-year period following nearly 800 Massachusetts smokers who had recently quit.

According to the scientists, the nicotine replacement therapies aren't really effective in getting cigarette addicts to give up their habit for the long term.

As a result, the researchers question whether the government should bother giving public funds for NRT's. Your thoughts? Tell us on Facebook.
