“…The findings of this study pointing out that male students have higher rates of use of illicit drugs than females whose preferences are more towards the more socially accepted licit psychotropic substances, are consistent with the international literature [2,11,44,45].…”

Objective: This study aims at examining the patterns of ‘substance’ use in Lebanon among an ’at risk’ population, the university students. Method: A stratified cluster sample of 1,851 students from two major universities was included in the study and the Diagnostic Interview Schedule (version 3) was administered. Results: The prevalence of nicotine users in the sample was 18.3% and of ever consuming alcohol 49.4%. 2.1% of the sample were alcohol abusers and 2.4% alcohol dependents according to DSM-III criteria. For the remaining substances, tranquilizers were found to have the highest rate of ever use (10.2%), whereas heroin had the lowest rate (0.4%); the rates of abuse and dependence in these categories (other than alcohol and nicotine) following DSM-III criteria ranged from 0.1 to 0.8%. Conclusion: University students in Lebanon in this study have relatively low rates of use and abuse of substances but this might be changing.

“…This scale was constructed according to a criterion of pain tolerance and has proven valid and reliable in a number of studies (for a review see Barnes, 1985). Reducers were found to be more pain tolerant than augmenters (Vando, 1974), to turn on a radio louder than augmenters , to consume more frequently psychoactive drugs than augmenters (Vulcano et al, 1990), and to be psychophysiologically and subjectively less reactive to intense auditory stimulation than augmenters (Davis, et al, 1984;Schwerdtfeger and Baltissen, 2002). In accordance with Petrie's theory these results suggest that reducers dampen down incoming stimuli and augmenters amplify them.…”

“…Both environmental and genetic factors play important roles in the comorbidity of CD with AD and MJ [Buckstein et al, 1989;DeMilio, 1989;Vulcano, et al, 1990;Johnson and Pandina, 1991]. McGue et al [1992] found that identical twin brothers of alcoholic probands were at increased risk of CD, which suggests a common familial contribution to CD and alcoholism.…”

Data from the Vietnam Era Twin (VET) Registry were analyzed to explore the degree to which the same genetic and environmental factors contribute to childhood conduct disorder symptoms and to alcohol and marijuana dependence symptoms. Data on conduct disorder and alcohol and marijuana dependence were obtained from administration of the Diagnostic Interview Schedule to 1,856 monozygotic and 1,479 dizygotic male-male twin pair members of the VET Registry. Multivariate genetic models were compared to determine the genetic and environmental influences common and or specific to all three phenotypes. A full model that allowed for common genetic and environmental influences to all three phenotypes gave a good fit to the data, but the best fitting reduced model did not allow for a genetic influence on conduct disorder symptoms. Under the best fitting reduced model, genes explained 44.7% of the variance in risk for alcohol dependence symptoms. The genetic liability for symptoms of marijuana dependence was due to a 36.3% specific contribution and a 7.6% contribution from genes common with alcohol dependence symptoms. Family environmental contributions common to all three phenotypes explained 46.7%, 11.9%, and 21.3% of variance in risk for symptoms of conduct disorder, alcohol dependence, and marijuana dependence, respectively. Common family environmental factors contribute to risk of conduct disorder symptoms and alcohol and marijuana dependence symptoms. Common genetic influences contribute to risk of symptoms of alcohol dependence and marijuana dependence. While our findings suggest genes do not contribute to co-morbid conduct disorder symptoms, comparisons with other twin studies suggest that the role of genes in risk for conduct disorder remains uncertain.
