Nicotine replacement therapy (NRT) can be a great way to help you stop smoking. Visit your local store for stop smoking advice and support with our Stop Smoking Service. Our pharmacists will be able to offer you further advice and information along with nicotine replacement therapy options. NRT comes in many forms such as gums, patches, sprays, inhalators and lozenges. E-cigarettes are not a form of nicotine replacement therapy but may be an option if nicotine replacement therapy doesn't suit you.
