US approves low-nicotine cigarettes

The US Food and Drug Administration (FDA) has approved the sale of two brands of reduced nicotine cigarettes. The FDA said that the approval was based on the potential for those products to help people quit smoking. However, the FDA also emphasised that the low nicotine cigarettes differ only in nicotine content and that they pose the same health risks as conventional cigarettes. The products contain 0.2 to 0.7 mg of nicotine per cigarette compared with 10 to 14mg in conventional cigarettes.
