We observe that increasing the values of δ, the endemic level of temporary quit smokers increases.
In this work, the population was divided in four subclasses: potential smokers, occasional smokers, smokers, and quit smokers.
It can also be observed that by increasing the factor η the endemic level of temporary quit smokers decreases.
Figures 4, 5, 6, 7, 8, and 9 represent endemic levels of smokers and temporary quit smokers for different values of the parameter.
The endemic level of smokers and temporarily quit smokers can be decreased or increased by decreasing or increasing the value of the different parameters.
It has also been observed that the endemic level of smokers and temporarily quit smokers is decreased by increasing the factor η. It means that the endemic level of smokers could be decreased through education and treatment campaigns to minimize the number of smokers and maximize the number of quit smokers in a community.
These observations suggest that enhancing the awareness in the population about the menace of smoking can motivate the smokers and temporary quit smokers to enter in the permanently quit smoking class.

There were five interview schedules developed to guide semi-structured interviews, including four for AHWs with a smoking history (i.e. ex-smokers, smokers not ready to quit, smokers unsure about quitting, and smokers ready to quit) and a final one for both non-AHWs and AHWs who had never smoked.
Expression levels of the most significant genes (e.g. LRRN3, CLDND1) were roughly equivalent in former smokers and subjects that had never smoked; likewise recently quit smokers appeared more like current smokers.
