Nicotine gum Nicorette – 105 pieces of 4 mg nicotine, with a mint flavor. It can be used both as a way to quit smoking (within nicotine replacement therapy) and as a supplement to improve concentration, focus, and reduce anxiety (for non-smokers) – this form is even used by some Nobel laureates. For quitting smoking, this pack can last 2-4 weeks of nicotine replacement therapy, and this pack is cheaper than cigarettes for the same period. 105 lari
