Table 1 Recruitment methods used in each country

Australia | 170 | In Australia we initially recruited 391 smokers to a survey on a smoking cessation website (http://www.quit.org.au). After the initial survey, smokers of 10+ cigarettes per day who said they were not planning to quit in the next month were told about the possibility of participating in a study that involved trying some alternatives to cigarettes. A total of 170 completed the second survey. Both surveys were completed on the internet. |
