Smoking is an important public health issue. The self help books may have important motivational implications which associated with deep breath exercises could cease the habit. Goals: Verify the effectiveness of the deep breaths exercises from the self help books along with the two motivational interventions to quit smoking on the anxiety, depression and daily consumption levels. Method: The study will be both prospective and controlled. Individuals will be distributed randomly in 4 different groups: The first group will be doing the deep breath exercises, the second group will read a self help book, the third group will do both reading and exercises and the fourth group will be the control. Anxiety, depression, motivational level and the cigarettes daily consumption will be evaluated previously and after the 15 days intervention. Expected results: Decreasing in anxiety, depression and cigarette consumption plus an increase in the motivation to quit smoking.
