Behavioral economic analysis of legal and illegal cannabis demand in Spanish young adults with hazardous and non-hazardous cannabis use.

Background: In October 2021, a legal framework that regulates cannabis for recreational purposes in Spain was proposed, but research on its potential impacts on cannabis use is currently limited. This study examined the reliability and discriminant validity of two Marijuana Purchase Tasks (MPTs) for measuring hypothetical legal and illegal cannabis demand, and to examine differences in demand of both commodities in young adults at hazardous vs. non-hazardous cannabis use risk levels.

Psychometric Validation of the Compulsive Internet Use Scale in Spanish Adolescents.

Despite problematic internet use being especially high among adolescents, there are no screening instruments in Spain specifically for adolescents that would facilitate early detection of this problem. The main goal of this study was to validate the Compulsive Internet Use Scale (CIUS) in the adolescent Spanish population as well as to analyze the discriminative capacity of CIUS based on sociodemographic characteristics, grade point average, and other addictive behaviors. Data were obtained from the ESTUDES, a representative survey of addictive behaviors of Spanish adolescents.
