Smoking kills more people in England than any other cause of preventable death. Worryingly in 2012, the number of people quitting had reduced every year since 2007. To combat this, we created Stoptober, the world’s first mass participation quitting event. Over the last five years we’ve evolved Stoptober using the latest technology, resulting in delivering the lowest cost per quit ever achieved last year. Stoptober has been copied by clinicians globally, won numerous awards including an IPA Effectiveness Gold last year and most importantly helped 1,600,000 smokers quit.
