[Pharmacy students' exposition to tobacco smoke--a trial of assessment of causes and prevalence].

Prevalence of tobacco smoking among young people is one of the most important aspects in prevention of smoking and smoking-related diseases. The aim of this study was assessment of pharmacy students' exposition to tobacco smoke (active and passive smoking) and searching for circumstances promoting tobacco smoking and exposition to ETS (environmental tobacco smoke). In the examined cohort of 161 students we found 37 smokers (23%; 21.2% women and 31% men), among them 14 (8.7%) everyday smokers. ETS affected 155 persons (96.3%) and usually took place in a circle of friends. The most common factors promoting tobacco smoking were: pleasure connected with smoking, smoking as a support in stress situation or as a facilitation of society functioning and getting to know new friends. We must emphasize again the leading role of prevention of smoking initiation in young people in all preventive activities.
