Effectiveness of Heroin-Assisted Treatment Compared With Methadone Maintenance

"Our results on the cost-effectiveness of diacetylmorphine are consistent with those of an economic analysis based on data from two Dutch heroin-assisted treatment trials,21 despite differences in the design of the Dutch trials and the North American Opiate Medication Initiative, and the time horizon and analytic design of the economic analyses.

Treatment Effectiveness at Reducing Levels of Drug Use

"During the course of treatment, many treatment seekers stopped using the drugs that they reported using at entry to the study. Lower rates of drug use were recorded at each follow-up. Furthermore, those that continued to use tended to use less. Most of the changes observed occurred by first follow-up. For most forms of drug use, no particular treatment modality was more associated with cessation than any other and the route into treatment (CJS or non-CJS) did not influence drug-use outcomes.

Trends in Treatment Admissions of People For Whom Their Primary Drug was Heroin or Other Opiates

"• Heroin was reported as the primary substance of abuse for 26 percent of TEDS admissions aged 12 and older in 2015 [Table 1.1b].

"• Sixty-seven percent of primary heroin admissions were non-Hispanic White (41 percent were males and 26 percent were females). Non-Hispanic Blacks made up 14 percent (9 percent were males and 5 percent were females). Admissions of Puerto Rican origin made up 7 percent of primary heroin admissions (6 percent were males and 1 percent were females) [Table 2.3b]. See Chapter 3 for additional data on heroin admissions.

Drug Overdose Deaths in the US, Polydrug Use, and Involvement of Prescription Pharmaceutical Drugs

"Of the 36,667 drug overdose deaths with at least one mention of a specific drug, 52% mentioned only one specific drug (18,931 deaths), 26% mentioned two (9,351 deaths), 12% mentioned three (4,521 deaths), 6% mentioned four (2,041 deaths), and 5% mentioned five or more (1,823 deaths). Among drug overdose deaths with at least one mention of a specific drug, the average number of specific drugs mentioned was 1.9.

Efficacy of Extended-Release Injectable Naltrexone

"Findings from a 24-week randomized controlled trial comparing extended-release injectable naltrexone (Vivitrol, Alkermes) to placebo in individuals with current opioid dependence have been considered in the recent indication for extended-release injectable naltrexone for the treatment of opioid dependence. In this trial, subjects having completed 30-day detoxification were recruited from 13 sites in Russia received either 380 mg intramuscular injections of extended-release naltrexone (n = 126) or placebo injection (n = 124) every 4 weeks for 24 weeks.


"Originally approved for use in the treatment of opioid dependence by the United States Food and Drug administration (FDA) in 1984, naltrexone is a competitive ?-opioid receptor antagonist with negligible agonist effects, blocking euphoric and physiological effects of opioid agonists.11,12 Naltrexone does not cause the development of dependence or tolerance over time, and dosing cessation does not result in withdrawal.13

Opioid Substitution Treatment and Risk of New HIV Infection Among IDUs

"There is evidence from published and unpublished observational studies that opiate substitution treatment is associated with an average 54% reduction in the risk of new HIV infection among people who inject drugs. There is weak evidence to suggest that greater benefit might be associated with longer measured duration of exposure to opiate substitution treatment.
