  1. Tobacco use is related to 5 million deaths annually1.
  2. The use of internet is growing exponentially around the word2.
  3. Many web-based tobacco interventions show promise for helping people quit.3,4. However, no open-source intervention for smoking cessation is available, and many countries have not tested these interventions, including Brazil..
  4. Open source facilitates the spread of interventions. Live without tobacco was entirely developed with free software. So you will be able to contribute and build over it without any licensing costs.5: "The code is written mainly in Java, being Android-friendly.."

Our methodology

The content is based on "Treating Tobacco Use and Dependence - 2008 an update" and recent research by Cochrane Collaboration.

Throughout the development stages, former and current smokers were consulted by means of collective interviews and usability tests. After the first version was ready, its content was evaluated by specialists from the tobacco use field.

The content agrees with the Code of Conduct of the Health on the Net Foundation, the Medical Federal Council, and the Federal Council of Psychology/Brazil.

Future studies

In the following years, we will evaluate the program's effectiveness. But first, we will improve the program using A/B Tests, Machine Learning and Data Mining.

We endorse open-science, so every research script and (unidentified) data will be available for everyone.
