Tobacco Free Initiative (TFI)

Quitting tobacco


Quitting tobacco is not easy as tobacco dependence is a cluster of behavioural, cognitive and physiological phenomena. Very few tobacco users can successfully quit the habit in their first attempt. But the evidence is strong that it can be done. From quit lines to counselling to prescription medicines, there are numerous effective ways to quit.

Strengthening health systems for treating tobacco dependence in primary care

This training package aims to assist countries in taking one of their first steps towards providing comprehensive tobacco dependence treatment to all tobacco users by integrating brief tobacco interventions into primary care.
