ABSTRACT
While many critics of the use of marijuana will grant the relative harmlessness of the drug, a large number oppose it on the sequential grounds that its use leads to the dangerous drugs, notably heroin. One selection in this section even sees cigarettes as a stepping stone in this process. Unfortunately for the sociologist who studies the drug question, the empirical relationship between the use of these two drugs has never been adequately tested. The researcher who wishes to do so is faced with an abundance of practical and methodological problems. No study, to the editor's knowledge, has surmounted these problems.
