Nasal and mouth sprays are cannisters that you spray into your nose or mouth to provide your body with a supply of nicotine.
Nicotine is highly addictive and is the main cause of the cravings associated with smoking cessation. Sprays can help you to break the habit of smoking tobacco whilst supplying nicotine to your body, which lessens the nicotine withdrawal symptoms. When you are ready, you can gradually reduce the frequency at which you use the spray until you no longer need to use it at all.
Nasal and mouth sprays are available via prescription from your doctor (in the UK) or you can purchase them over-the-counter in most pharmacies.
They are recommended for use by very heavy smokers because they work much faster than other forms of NRT.
Popular brands include NiQuitin, Nicorette and Nicotinell
