Controlled, Encouraged or Adrift? Sources of Variation in Adolescent Substance Use

The frequent consumption of alcohol and cannabis by youth poses both concern and ambivalence to society about the nature of the problem and how to respond. In the last few decades, social science research has devoted considerable attention to substance use among youth, making it an important issue to consider; however, controversy abounds when considering where consumption patterns of youth fall on a continuum from normal to deviant. Central to these debates is the social acceptability of the substances being used, their legal status, the frequency with which they are consumed, and the particular groups most often engaged in their use. Youth who consume alcohol are viewed with less trepidation than those who consume cannabis. Moreover, those who use either substance recreationally or experimentally are deemed to be more typical than those who have escalated their use to more regular or frequent episodes. Finally, drug-using youth who are embedded in conventional society are viewed more positively than those who occupy the margins of society, such as those who are delinquent or homeless. To fully understand the debate about the deviancy versus the normalcy of adolescent substance use, more inclusive approaches that take into account structural, individual and situational explanations are needed; however, existing studies fail to consider all of these influences. Instead, there is debate about the dominance of each of these explanations. This dissertation examines and tests these competing representations and explanations of adolescent substance use by drawing on multiple sociological theories of deviance including control theories, differential association theory, routine activity approaches, and drift theory. Using a combined sample of high school students and street youth, the findings suggest that adolescent substance use is far too complex to be explained by only one theory. Instead, explanations for the variations in substance use must take into account both individual backgrounds and more immediate situational influences. Most importantly, individual beliefs about substances are an important and often ignored aspect of individual substance use patterns.Ph
