Concurrent Multiple Drug Use: Review and Implications

Abstract: Evidence supporting individual generalized tendencies to use psychoactive drugs is reviewed. As a given drug is used or abused more heavily, a wider range of other drugs tends to be used in concurrent patterns. Multiple drug use must enter our conceptions of abuse, as the acute and chronic consequences attributed to a given drug are often confounded by the concurrent use of other drugs. Indeed, the use of one drug may be a contributing cause of the use of others. Social policies directed toward intervention an… Show more

“…Gradations from nonuser to initiate, from initiate to regular user, and from regular to high user (and dependence) may mark changes in the effects of family variables, and these changes may not be of a linear kind. Yet another consideration to be taken into account is the effect of multiple drug use (Sadava, 1984). A youth who smokes 50 cigarettes a day but is not involved with other drugs is surely at a different point in terms of prediction than a youth with the same cigarette consumption who is heavily involved with other drugs.…”

“…Loneliness was measured with the revised 20-item UCLA scale (Russell, Peplau, & Cutrona, 1980), and locus of control with the Reid and Ware (1974) instrument, including factor-analytically derived subscales representing fatalism (concern with luck or chance regarding personal outcomes), self-control (concern with personal impulses and desires), and social system control (concern with political and social influences). The alcohol questionnaire (described more fully in Sadava, 1984) includes measures of alcohol consumption, problems, and social variables referring to the past six months. Consumption is measured by quantity-frequency (Q-F), the product of the "typical" quantity consumed per occasion and the frequency of drinking occasions, and by the frequency of intoxication during that period.…”

“…Our findings in regard to multiple drug experimentation are congruent with those of other investigators. Sadava 29 has noted that there is substantial covariation among the patterns of use of various drugs; as one drug is used more heavily, a wider range of other drugs tends to be used concurrently. Interestingly, in this sample, once severe cocaine use was initiated it tended to displace use of other drugs.…”
