Female volunteers of childbearing potential (including women who are less than 1 year postmenopausal and women who will be sexually active during the study) must agree to use a medically accepted method of contraception or must be surgically sterilized prior to screening, while receiving protocol-specified medication, and for 30 days after stopping the medication. Women who have been postmenopausal for >=1 year (ie, women who have experienced 12 or more consecutive months of amenorrhea) will be exempted from the requirement to use contraception during the study. Acceptable methods of contraception include condoms (male and female) with or without a spermicidal agent, diaphragm or cervical cap with a spermicidal agent, medically prescribed intrauterine device, oral or injectable hormonal contraceptives, and surgical sterilization (eg, hysterectomy or tubal ligation).
• Female participants of childbearing potential must have a negative urine beta-human chorionic gonadotropin (beta-hCG) test prior to enrollment in the study

Exclusion Criteria

• Participants for whom treatment with either Subutex or Suboxone as required in the protocol would be inconsistent with national labeling.

• Participants who are participating in any other clinical study in which medication(s) are being delivered.
• Participants with known allergy or sensitivity to buprenorphine or naloxone.

• HIV-positive participants with clinical acquired immunodeficiency syndrome (AIDS).
• Methadone or buprenorphine maintenance or detoxification within 30 days of enrollment.
