School bullying and cyberbullying are serious public health problems that negatively affect the lives of school-aged children. We examined the correlation between risk behaviors and lack of resiliency factors with bullying and cyberbullying across seven Mediterranean countries. The sample consisted of 33,399 adolescents (51.1% girls) aged 11, 13,…

The aim of this study was to examine trends in cannabis use among Spanish students from 2006 to 2018 by sex, age, and sex and age combined. Data showed a global decrease both in a lifetime and frequent cannabis use between 2006 and 2018 but four-year comparisons revealed more variability within the specific sex-age groups. No change was found in…

Practicing physical sport activity is considered one of the most representative habits of a healthy lifestyle, and can act as a preventive factor in drug use. The physical self-concept of the people who practice sport plays a…

This research focuses on the analysis of cannabis consumption amongst young people, explaining this phenomenon by way of analysing the differences between cannabis smokers and non-smokers in order to shed light on whether cannabis is linked to specific leisure activities, and, moreover, whether it is connected to the intensity and variety of…

The aim of this study is to analyze the effects of parental knowledge, parental support, and family conflict through the affiliation with deviant peers on youth substance use (i.e., alcohol, cannabis, and other illicit substances), as well as unhealthy and antisocial behavior derived from substance consumption. A Spanish community sample was used…

Drug use in mainstream rave parties has been widely documented in a large number of studies. However, not much is known about drug use in underground raves. The purpose of this study is to find out the polysubstance use patterns at underground raves. Two hundred and fifty-two young people between the ages of 18 and 30 who went to underground raves…

The aim of this paper is to explore the influence of peer behaviour on student marijuana consumption. Our hypothesis is that, in contrast to the traditional measures of peer group effects carried out at class or school level, the use of a closer peer group, which we relate to the group of friends, is more relevant in the explanation of marijuana…

This paper examines the hypothetically bi-directional relationship which links marijuana consumption and school failure among students. To that end, we propose a simultaneous probability model, which is estimated by using the information provided by the three consecutive waves from the Spanish Surveys on Drug Use in the School Population [(1996,…
