This study examines the spread of smoking behavior based on economic factors and psychological factors. This model divides the population into 4 subpopulations, namely potential smoker , Beginner smoker , Smoker subpopulation  and recovery subpopulation  The stability of the smoking-free equilibrium point is obtained by linearizing the equation to obtain the Jacobian matrix and then the eigenvalues will be obtained. The basic reproduction number which is the threshold for the spread of smoking behavior where smoking behavior will disappear if  Ro < 1 and will be endemic when Ro > 1. ER -
