Tobacco control programs are necessary to face the high prevalence of smoking, especially among youth who are vulnerable in face of all this media affection, peers and parental smoking. This study is operational research, done in three major stages; pre-intervention assessment stage for both the tobacco control system in Egypt and for smokers characteristics, intervention stage which includes tailoring a behaviour change module which is the core tool for this study, upon which the service providers were trained on to provide smokers with evidence-based counselling, post-intervention stage where there was measuring of degree of change of participants' KAP after the counselling. Main results of this study; there were no nicotine replacement therapy or other pharmacological medications for tobacco control in both sectors; MOH and NGOs. As for age of initiation, 63% of the NGO group started smoking before the age of 18 versus 73% of MOH group. When they were asked about what they most prefer about smoking both groups voted more for considering smoking as a tool to deal with pressure, followed by sharing this practice with siblings and friends. As for the major difficulty they face to quit, NGO group voted more being under stress, while MOH group voted more for not having enough well to quit. For those who tried to quit before and failed, the main cause for failure for the NGO group was having smoking friends (60.7%), followed by going through stress (50.8%), while for the MOH group, going through stress was the main cause (73%) followed by having smoking friends. Main post-intervention results; The number of smoked cigarettes/ day had improved by 50% for NGO versus 43.78% for GCH, smoking preference score had improved by 14.69% for NGO, versus 1.67% for GCH, the disliking aspects of smoking in participants point of view had strengthened by 17.62% for NGO versus no change for MOH, and their quitting difficulties had improved by 6.63% for NGO versus no change for MOH, while their knowledge regarding smoking health hazards had improved for both, by 60.94% for NGO and by 32.9% for MOH. Main conclusion of this study is using behavioural therapy based on scientific manual can alone improve smokers KAP, and encourage quitting. The main recommendation is to train all personnel interacting with smokers on frequent base on tobacco control counselling using scientific manual specified for behavioural change, and make available access for medications for synergistic results with behavioural therapy.
