W1 T2; Harms associated with drug use



Environmental risk Adolescence
 Initiation typically happens during adolescence; experimentation is normal
 Minority escalates to frequent problematic drug use
 Peak period for onset and dependence; therefore addiction
 Adolescent brain sensitive to drugs
 Animal research:
o Shows lower sensitivity in adolescents to aversive effects of being drunk,
sedation, hangover and ataxia
o Increased sensitivity to social facilitation and spatial memory disruption
o However, problematic to extrapolate animal studies and only looks at alcohol

 A cause is not the only cause and is not necessary/sufficient for addiction
 A cause is an event that increases probability of risk e.g. smoking increases prob of
lung cancer


Risk factors
 Old review by Hawkins et al, 1992, categorised risk factors






 Summarised above categories; perhaps need to be reassessed and updated
 Effect of risk factors is independent of potential confounding covariates
 Longitudinal/prospective and twin/adoption research useful in studying these
 Increases accuracy of timing of risk events and can assess many covarities
