In the earliest reports, the approach involved drug users). Often, the analyses to disclose variation are not guessing the number of untreated or nonincarcerated drug intended to produce links in a chain of causal inferences. Examples of Epidemiologic Evidence This workis at the margin of the scientific enterprise. As a source of authoritative scientific evidence, it is of Two of the most robust findings from epidemiologic studies dubious value and based on assumptions that are not well on the location of drug dependence cases within population tested and may never be testable. In a brief, pithy article, subgroups are a male excess and an excess in the age group Newman and Cates (25) made this point 30 years ago, quot- 15 to 44 years old, disclosed by both prevalence differences ing from the classic study by Terry and Pellens (26): 'As and relative riskestimates (see ref.
