This is likely to change from now on, "said Peter Hajek, a researcher at the Kueen Mari Universiti in London.
In a clinical trial 886 smokers participated who went to the health centers in search of help to give up. Doctors randomly divided them into two groups. The first group received a replacement for nicotine of their choice, such as patches, chewing gum, pills or inhalers, which should last up to three months.

In addition, all participants received support sessions with healthcare staff for four weeks.
