Abstract:Cannabis use is rarely a trigger for grade repetition but can have either damaging or positive effects on school attainment depending of the level of use. Positive social competence reflected by peer initiation should be investigated to understand this paradoxical effect.
“…These patterns are consonant with literature indicating that cigarette smokers over time, especially young cigarette smokers, are becoming increasingly prone to externalizing behaviors (Chassin et al, 2007; Legleye et al, 2010; Little et al, 2008). Similar overall patterns were observed for the internalizing disorders, although it should be noted that for both GAD and MD, rates among the two smoking groups increased across initial cohorts then held constant, and in the final cohort, decreased.…”
Background:
In recent decades, smoking has become an increasingly non-normative behavior. Because deviant behaviors are associated with greater clinical and genetic risks, current-generation smokers may have greater concentrations of psychiatric comorbidity than previous generations. We examined this question empirically by testing whether associations between measures of smoking, psychiatric diagnoses, and riskassociated personality traits, increased across seven birth-cohorts of the 20th century.
Method:
4,326 subjects from a cross-sectional NIMH control sample were categorized into one of seven groups based on birth (born before 1930, and 1930s-‘80s) and one of three smoking levels (lifetime dependent smoker, never dependent smoker, never smoker smoking and ND were assessed using the Fagerstrom Test for Nicotine Dependence; psychiatric diagnoses (drug and alcohol dependence, major depression, and generalized anxiety disorder) using the Composite International Diagnostic Interview-Short Form, and personality traits (neuroticism and extraversion) with the Eysenck Personality Questionnaire.
Result:
Lifetime prevalence of smoking decreased across the seven cohorts. Associations between smoking and drug dependence, generalized anxiety, and neuroticism, as well as total psychiatric comorbidity, were greater in more recent cohorts [smoking-by-cohort interaction: p<0.01], with greatest increases contributed by nicotine-dependent smokers. Smoking was also independently associated with alcohol dependence and depression, but these associations did not significantly vary across cohorts.
Conclusions:
More recent generations included fewer persons who smoked, but their smoking was associated with greater psychiatric morbidity. Failure to account for systematic variation in comorbidity across smoking cohorts may lead to unwanted heterogeneity in clinical, and possibly genetic, studies of nicotine dependence.

“…Results about school were consistent with former research, which showed that leaving school without qualification was linked to prior cannabis use (Fergusson et al, 2003), and early initiation of cannabis use with subsequent use (Legleye et al, 2009), while school connectedness was associated with less frequent cannabis use (Resnick et al, 1997). We found that teenagers who indicated they did not like school at all were nearly twice as at risk for cannabis experimentation.…”

“…Cannabis consumption also was linked to low academic performance (Cox, Zhang, Johnson, & Bender, 2007) and increased risk of leaving school without qualification (Fergusson, Horwood, & Beautrais, 2003). Cannabis initiation before 14 with subsequent daily use was associated with school dropout at 17 (Legleye et al, 2009).…”
France presents one of the highest prevalence of teenagers aged 15-year-olds who report they already have experienced cannabis in Europe. Data from the French 2010 Health Behavior in School-aged Children (HSBC) survey and environmental parameters typifying schools' neighborhoods were used to study cannabis experimentation. We conducted a two-level logistic regression (clusters being schools) on 4,175 French 8th-10th graders from 156 schools. Several individual parameters were linked to cannabis experimentation. Living in a non-intact family, feeling insufficiently monitored, having poor communication with mother and being from a family with a high socio-economic status (SES) were all associated with increased risk of cannabis experimentation. At environmental level, only being in a priority education area was linked to this behavior, without explaining differences among schools.
“…In France, Huerre and Leroy [6] presented a holistic analysis of school dropout, Brandibas [7] considered truancy to be associated with different types of anxiety, whereas Legleye [8] reported an association between dropout and the progression to daily cannabis use. Jonsson [9] pointed out that Swedish adolescents suffering from depression were less likely than their non-depressed peers to have graduated from higher education.…”
BackgroundIn Luxembourg, the extensive phenomenon of school dropout is a prime policy concern in the light of individual, social and economic consequences. Although the authorities report an overall decrease of the national dropout rate, the proportion of early school leavers who remain without any specific occupation is still alarming. Therefore, this study intends a shift of focus from system-inherent to individual factors, including mental health and family correlates, to provide a more comprehensive analysis of the dropout phenomenon.Methods/DesignThe objectives of this study are to investigate the type and prevalence of psychiatric disorders among school dropouts and to compare the findings with those by a matched control group of regularly enrolled students. Furthermore, family variables and socioeconomic status will be analysed, as they are factors likely to interfere with both educational attainment and mental health. A trained psychologist will use structured interviews and self-report forms to investigate for mental health issues, information on schooling, socioeconomic situation and family life. Controls will be matched for gender, age, school type and educational grade.DiscussionAs school dropouts face a serious risk of long term professional and social marginalization, there is an evident need for action. Identifying psychosocial risk and protective factors of school dropout will deliver solid insight on how to conceive public health strategies for young people who may need a more customized support to carry out their academic potential.Trial registrationClinicalTrials.gov Identifier: NCT01354236
