Marijuana-dependent young adults (N = 136), all referred by the criminal justice system, were randomized to 1 of 4 treatment conditions: a motivational/skills-building intervention (motivational enhancement therapy/cognitive-behavioral therapy; MET/CBT) plus incentives contingent on session attendance or submission of marijuana-free urine specimens (contingency management; CM), MET/CBT without CM, individual drug counseling (DC) plus CM, and DC without CM. There was a significant main effect of CM on treatment retention and marijuana-free urine specimens. Moreover, the combination of MET/CBT plus CM was significantly more effective than MET/CBT without CM or DC plus CM, which were in turn more effective than DC without CM for treatment attendance and percentage of marijuana-free urine specimens. Participants assigned to MET/CBT continued to reduce the frequency of their marijuana use through a 6-month follow-up.

    • "Arguably, the most effective outpatient treatments for CUD combine Motivational Enhancement Therapy (MET), CBT, and Contingency Management (CM; Budney et al., 2006; Carroll et al., 2006, 2012; Kadden et al., 2007; Litt et al., 2013). Although limitations have been raised with real-world implementation of such interventions due to availability and cost (Carroll, 2014), recent studies suggest that computer-assisted versions of these treatments may enhance access and reduce cost without sacrificing efficacy (Budney et al., 2011, 2015; Kay-Lambkin et al., 2009, 2011).

    ABSTRACT: Cannabis users frequently report concurrent tobacco use, and tobacco use is associated with poorer outcomes during treatment for cannabis use disorders (CUD). Interventions that simultaneously target both tobacco and cannabis use disorders may enhance cessation outcomes for either or both substances. This study evaluated an intervention integrating highly effective treatments for cannabis and tobacco use disorders. Thirty-two participants meeting diagnostic criteria for CUD and reporting daily tobacco use were enrolled in a 12-week computer-assisted behavioral treatment for CUD. Participants were encouraged to participate in a tobacco intervention that included a computer-assisted behavioral treatment tailored for tobacco and cannabis co-users, and nicotine-replacement therapy (NRT). Cannabis and tobacco outcomes were evaluated using descriptive statistics and were compared to a historical control group that received treatment for CUD but not tobacco. Participants achieved 3.6±4.3 consecutive weeks of cannabis abstinence, which was comparable to the historical control group (3.1±4.4). A majority of the sample (78%) completed at least one tobacco module and 44% initiated NRT. Over half (56%) initiated tobacco quit attempts, and 28% were tobacco abstinent for at least two consecutive weeks. Participants showed greater reduction in tobacco use (cigarettes per day) than the historical control group, but differences in tobacco abstinence rates during the final month of treatment were not statistically significant (12.5% vs. 4%). Findings suggest that providing a tobacco intervention during treatment for CUD is feasible and may positively impact tobacco use without negatively affecting cannabis use outcomes.

    • "Third, rate of relapse, that is, change in abstinence over the posttreatment period, did not differ among the three conditions, which supports the hypothesis that treatment effects on cannabis abstinence over time would not differ between THERAPIST and COMPUTER delivered MET/CBT/CM conditions. This observation , if replicated, provides a particularly important contribution to the effectiveness literature because some, but not all, prior studies of therapist-delivered MET/CBT/CM have demonstrated that the MET/CBT component enhanced maintenance of posttreatment abstinence outcomes engendered with CM (Budney et al., 2006; Carroll et al., 2006, 2012; Kadden et al., 2007; Rawson et al., 2006).

    ABSTRACT: Computer-assisted behavioral treatments hold promise for enhancing access to and reducing costs of treatments for substance use disorders. This study assessed the efficacy of a computer-assisted version of an efficacious, multicomponent treatment for cannabis use disorders (CUD), that is, motivational enhancement therapy, cognitive-behavioral therapy, and abstinence-based contingency-management (MET/CBT/CM). An initial cost comparison was also performed. Seventy-five adult participants, 59% Black, seeking treatment for CUD received either, MET only (BRIEF), therapist-delivered MET/CBT/CM (THERAPIST), or computer-delivered MET/CBT/CM (COMPUTER). During treatment, the THERAPIST and COMPUTER conditions engendered longer durations of continuous cannabis abstinence than BRIEF (p < .05), but did not differ from each other. Abstinence rates and reduction in days of use over time were maintained in COMPUTER at least as well as in THERAPIST. COMPUTER averaged approximately $130 (p < .05) less per case than THERAPIST in therapist costs, which offset most of the costs of CM. Results add to promising findings that illustrate potential for computer-assisted delivery methods to enhance access to evidence-based care, reduce costs, and possibly improve outcomes. The observed maintenance effects and the cost findings require replication in larger clinical trials. (PsycINFO Database Record (c) 2015 APA, all rights reserved).

    • "Las estrategias que se pueden abordar van acompañadas tanto de medicamentos que ayudan a tratar el síndrome de abstinencia y evitar recaídas.Dentro de las estrategias terapéuticas conductuales se encuentran la realización de terapias cognitivoconductual , entrevistas de motivación y terapias grupales (NIDA, 2008NIDA, , 2010Engle, 2011;Smedslund et al., 2011). La terapia cognitivo-conductual tiene como objetivos identificar y modificar las actitudes y comportamientos relacionados al consumo y abuso de drogas (Carroll et al., 2006). Para poder manejar las recaídas, se requiere adquirir destrezas que le hagan contrapeso al aprendizaje disfuncional causado por las drogas. "
