Over 13 million smoke in the UK and of these over 70% report that they would like to stop. There is also ever increasing political and social pressure towards introducing public smoking bans and limiting the visibility and availability of cigarettes. Long term success is low for individuals seeking to quit smoking. Less than 20% achieve their goal using willpower or nicotine replacement methods and 40% using pharmaceutical approaches. Such treatments are also relatively expensive and have some undesirable side effects. This presents an unmet need and an opportunity for a novel intervention for smoking cessation.   It has been found that inhalation of air enriched with a specific concentration of CO2 acts to significantly reduce cravings in abstinent smokers. These findings offer a novel treatment method for the cessation of smoking. Additional work will be required by a partner to validate the method and develop an appropriate delivery means for the CO2 enriched air.
