How Does one Become a Cannabis Smoker ?
A Quantitative Approach
[*]
Patrick Peretti-watel
Howard S. Becker’s study of the “career” of marijuana smokers became a reference for
later ethnographic studies but has hardly been an inspiration for epidemiologists’ statistical
studies. This article aims first to better understand this apparent incompatibility by pointing
out the pitfalls epidemiologists are exposed to when they analyze drug use. It then reexamines available data, with the purpose of drawing from Becker’s theses a set of hypotheses
that can be statistically validated. Lastly, these hypotheses are validated on the basis of responses to a self-administered questionnaire survey of 12,113 teenage pupils conducted in
1999 in mainland France. The results confirm the relevance of Becker’s sequential approach
for cannabis use, since they show that 1) use-related factors, namely type of supply point
and use among peers, vary by cannabis consumption level; 2) the neutralization techniques
Becker hypothesized may be seen to be operative in respondents’ stated opinions. More generally, the article illustrates the possible complementarity between statistical and ethnographic approaches.
