Prescription Drug Diversion: Predictors of Illicit Acquisition and Redistribution in Three U.S. Metropolitan Areas

Objective
Prescription drug diversion, the transfer of prescription drugs from lawful to unlawful channels for distribution or use, is a problem in the United States. Despite the pervasiveness of diversion, there are gaps in the literature regarding characteristics of individuals who participate in the illicit trade of prescription drugs. This study examines a range of predictors (e.g., demographics, prescription insurance coverage, perceived risk associated with prescription drug diversion) of membership in three distinct diverter groups: individuals who illicitly acquire prescription drugs, those who redistribute them, and those who engage in both behaviors.

Methods
Data were drawn from a cross-sectional Internet study (N = 846) of prescription drug use and diversion patterns in New York City, South Florida, and Washington, D.C.. Participants were classified into diversion categories based on their self-reported involvement in the trade of prescription drugs. Group differences in background characteristics of diverter groups were assessed by Chi-Square tests and followed up with multivariate logistic regressions.

Results
While individuals in all diversion groups were more likely to be younger and have a licit prescription for any of the assessed drugs in the past year than those who did not divert, individuals who both acquire and redistribute are more likely to live in New York City, not have prescription insurance coverage, and perceive fewer legal risks of prescription drug diversion.

Conclusion
Findings suggest that predictive characteristics vary according to diverter group.

...3.2. Illicit Acquirer
Table 2 shows results from three separate regression analyses (one for each diversion classification group). For the acquirer group, age was negatively associated with illicit acquisition (β = −0.02, OR = 0.98, p < 0.05). Also, having a history of having a licit prescription for any class of drug assessed in this study was positively associated with illicit acquisition (β = 1.14, OR = 3.24, p < 0.001). Area of residence, race, gender, education, being a student, income, prescription insurance coverage, perceived legal risk of prescription diversion, and perceptions of legal risk of illicit drug diversion were not associated with membership in the illicit acquirer group.

3.3. Illicit Redistributor
For the redistributor group, regression analyses demonstrated that age was negatively associated with illicit redistribution (β = −0.04, OR = 0.97, p < 0.01). As with illicit acquisition, a history of having a licit prescription for any class of drug assessed in this study was positively associated with illicit redistribution (β= 0.89, OR = 2.44, p < 0.05). Additionally, perceived legal risks of prescription diversion was negatively associated with redistribution (β = −0.87, OR = 0.42, p < 0.01). Area of residence, race, gender, education, being a student, income, insurance coverage, and perceptions of legal risk of illicit drug diversion were not associated with membership in the illicit redistributor group.

3.4. Illicit Acquirer/Redistributor
Regression analyses demonstrated several main effects for individuals involved in both illicit acquisition and redistribution. As with the illicit acquisition and redistribution groups, age was negatively associated with both illicit behaviors (i.e., acquisition and redistribution) (β = − 0.05, OR = 0 .95, p < 0.001) and a history of having a licit prescription for any class of drug assessed in this study was positively associated with both illicit behaviors (β = 1.86, OR = 6.44, p < 0.001). However, there were some differences with the combined group. First, compared to participants in New York City (referent), participants in South Florida were less likely to participate in both illicit acquisition and redistribution of prescription drugs (β = − 0.91, OR = 0.40,p < 0.05). Second, perceived legal risks of prescription drug diversion was negatively associated with being in the combined illicit acquisition and redistribution group (β = − 0.71, OR = 0.49, p < 0.05). In fact, those who engaged in both illicit acquisition and redistribution had the lowest perception of legal risk associated with prescription and illegal drug diversion of all the groups assessed (see Table 1). Finally, participants who had insurance with prescription drug coverage were less likely to engage in both acquisition and redistribution than those without such coverage (β = − 0.97, OR = 0.38, p < 0.05). Race, gender, education, being a student, income, and perceptions of legal risk of illicit drug diversion were not associated with membership in the illicit acquirer/redistributor group...
