In 2013, the US Food and Drug Administration launched its Population Assessment of Tobacco and Health (PATH) study, attempting to improve its understanding of tobacco use behaviour. Collecting data from 46,000 US residents aged 12 and over from people who may or may not use tobacco, e-cigarettes are one of the topics the study is investigating. Depending on the data, the FDA may suggest future tobacco regulations. The study ends in 2022. The data has revealed that 5% of adults in the study had used an e-cigarette in the past month. 40% of vapers used their e-cigarette less than three times in the last 30 days. 8% of current e-cig users also currently use tobacco. 83% of 18 to 24 year old vapers prefer flavoured e-cigarettes. 63% of adults older than that prefer flavoured e-cigarettes. E-cigarettes continue to surge here in the UK. With a reported 2.6 million users, thousands of vapers are quitting.
