“…First, intranasal users remained in treatment longer than smokers of cocaine, which was consistent even after removing the sample of methadone-maintained participants, who are likely to remain in treatment longer due to the need for daily opioid maintenance medications. While the effectiveness of treatment retention toward improvement in drug use remains questionable (Pearson et al, 2012), treatment retention is often cited as a key outcome measure and several lines of research have reported positive relationships between treatment duration and drug use outcomes (C.-Y. Chen & Lin, 2009; De Giorgi et al, 2012; Khalsa, Tashkin, & Perrochet, 1992; Ruiz, Cleary, Nassiri, & Steele, 1994; Welch, Todd, & Krause, 1991).…”

Smoking cocaine achieves maximal concentration and effect far more rapidly than through the intranasal (‘snorting’) route, and it is associated with greater propensity for dependence and more severe consequences. However, very little is known about differences in treatment outcome according to route of administration. This study compared treatment outcomes, such as frequency of cocaine use and Addiction Severity Index (ASI) composite scores, by primary route of cocaine administration (smoking vs. intranasal) among a pooled sample of 412 cocaine-dependent individuals participating in one of five randomized clinical trials. The majority (80%) reported smoking as their primary route of cocaine administration. Overall, results indicated better cocaine use outcomes both during the treatment phase and through a 12-month follow-up period for intranasal users compared to smokers, although not all differences reached statistical significance. Intranasal users remained in treatment longer [F(1,408) = 3.55, p < .05], and showed a trend toward achieving longer periods of sustained abstinence within treatment [F(1,378) = 2.68, p = .08], as well as less use over time during the follow-up period than smokers (Time x Route: t = 1.87, p = .06). Also, intranasal users’ ASI cocaine composite score decreased more than smokers, but there were overall decreases in the other ASI domains for all participants over the course of the study period. These results suggest that intranasal users may achieve better cocaine use outcomes than smokers, yet this doesn't appear to translate to differential changes in the severity of problems experienced in other life areas.

Objectives The purpose of the present meta-analysis was to answer the question: Can the Andrews principles of risk, needs, and responsivity, originally developed for programs that treat offenders, be extended to programs that treat drug abusers? Methods Drawing from a dataset that included 243 independent comparisons, we conducted random-effects meta-regression and ANOVA-analog meta-analyses to test the Andrews principles by averaging crime and drug use outcomes over a diverse set of programs for drug abuse problems. Results For crime outcomes, in the meta-regressions the point estimates for each of the principles were substantial, consistent with previous studies of the Andrews principles. There was also a substantial point estimate for programs exhibiting a greater number of the principles. However, almost all of the 95% confidence intervals included the zero point. For drug use outcomes, in the meta-regressions the point estimates for each of the principles was approximately zero; however, the point estimate for programs exhibiting a greater number of the principles was somewhat positive. All of the estimates for the drug use principles had confidence intervals that included the zero point. Conclusions This study supports previous findings from primary research studies targeting the Andrews principles that those principles are effective in reducing crime outcomes, here in meta-analytic research focused on drug treatment programs. By contrast, programs that follow the principles appear to have very little effect on drug use outcomes. Primary research studies that experimentally test the Andrews principles in drug treatment programs are recommended.

“…Although empirical replications of Risk × Treatment Interactions are needed to confirm principled findings, evaluation research is being extended to concentrate on the characteristics of offenders in which programming can be designed to have its optimal effect with regard to recidivism reduction. Generally, 240 D. Routh and Z. Hamilton interventions that incorporate RNR into participant selection and program design are identified to improve reentry outcomes upon release (Pearson et al, 2012;Prendergast, Pearson, Podus, Hamilton, & Greenwell, 2013).…”
