The psychosocial behaviour of young Spanish smokers

This paper studies the psychosocial behaviour of Spanish smokers between the ages of 14 and 18, with the aim of identifying the factors associated with both the decision to consume tobacco and the quantities to consume. To that end, a Type II Tobit model is used, which is estimated by using data drawn from the Spanish Surveys on Drug Use in the School Population corresponding to 1994, 1996, and 1998. The results show that the two decisions are strongly associated with a number of psychosocial determinants. In particular, evidence was found that the probability of smoking and the quantity consumed are positively related to variables such as the age of the adolescent, his/her disposable income, or education failure. The estimates also show that the realization of informative campaigns about the risk of tobacco and other substance abuse reduces both the proportion of smokers and the number of cigarettes consumed.
