Study Arms (2)

Mobile-phone app for smoking cessation

EXPERIMENTAL

The intervention arm will receive a smoking cessation program based on a mobile-phone app. The program contains strategies to support smoking cessation, including motivational messages, tips on stress management, on how to ask support from friends and family, how to use distraction techniques and how to deal with cravings, lapses and early relapse. It also includes a saving calculator, a "help button" which provides extra messages in case of cravings and a "lapse button", which provides advice about what to do if the participant presents lapses or relapse after being abstinent at least 24 hours.

Behavioral: Mobile-phone app for smoking cessation

Control mobile-phone app

PLACEBO COMPARATOR

The control arm will receive a mobile-phone app which will send 1 message every two weeks thanking participants for taking part in the study, and encouraging them to stay in the study for the 6 month follow-up period.

Eligible participants will be randomized to the intervention group or control group using a computerized and automated process. An email will be automatically sent to the participants with the link to download the corresponding version of the mobile-phone app (intervention app or control app). Researchers who will gather data and those who will measure carbon monoxide in exhaled air will be masked to treatment allocation.
