Nicotine is the addictive substance found in cigarette smoke. Nicotine Replacement Therapy (NRT) helps you to quit by giving you control of your craving for nicotine by gradually reducing the amount of nicotine in your body.

NRT is a safe and clean version of Nicotine which is effective.

  • Nicotine patches are long acting (16 or 24 hours).
  • Gum, sprays, inhalators, micro tabs and mouth strips are short-acting and can be used along with a patch.

E-cigarettes also contain nicotine but are not yet licensed in the UK as a quit smoking product and are not available via NHS clinics. Long term effects of using E-cigarettes are not yet known. More research is needed to show if they are safe and effective or not especially for long term use.


If you are using home oxygen you should not smoke or use E-cigarettes as there is a danger of fire or explosion from oxygen rich environment around you and some E- cigarette rechargeable units.
