Brief Summary:
The aim of this project is to conduct a multi-site effectiveness study to determine whether the addition of a monthly injection of depot naltrexone to treatment as usual (TAU) will significantly improve outcome in parolees and probationers with a history of opioid addiction compared to TAU alone. Participants will be randomized to either treatment as usual in community programs or monthly injections of depot naltrexone for six months with treatment as usual in community programs. The effectiveness of depot naltrexone has never been studied in opioid dependent parolees. all parolee subjects will be evaluated at baseline, while in treatment, and at 6, 12 and 18 month post entry time points. The primary study outcomes are retention in treatment, drug use, re-arrests, psychosocial and medical/psychiatric functioning, and economic costs and benefit costs of naltrexone.

Arm Intervention/treatment
Active Comparator: Depot Naltrexone Drug: Depot naltrexone
Vivitrol® extended release naltrexone 380 mg per month delivered in monthly intramuscular injections.

Placebo Comparator: Placebo Other: Treatment as Usual (TAU)
Treatment as Usual (TAU) community treatment provided to the participant

Primary Outcome Measures :
  1. Relapse [ Time Frame: 6 months ]
    A relapse event was defined as 10 or more days of opioid use in a 28-day (4-week) period as assessed by self-report or by testing of urine samples obtained every 2 weeks; a positive or missing sample was computed as 5 days of opioid use.

    3. Active medical illness that might make participation hazardous (e.g., untreated hypertension, hepatitis with AST or ALT >3 times upper limit of normal, unstable diabetes or heart disease). Adequately treated medical conditions are acceptable; 4. female subjects who are pregnant or lactating, or female subjects of childbearing potential who are not using birth control (oral contraceptives, barrier (diaphragm or condom) plus spermicide, or levonorgestriel implant); 5. Liver failure or liver function test levels greater than three times normal; 6. History of allergic reaction to naltrexone; 7. History of a drug overdose in the past 3 years; and 8. Current diagnosis of chronic pain disorder for which opioids are prescribed for pain relief.
