MTD = methadone — what it is and how it's dispensed
Methadone is a Schedule II controlled substance regulated under both DEA and SAMHSA OTP rules. It is dispensed in two primary contexts:
- Maintenance treatment for opioid use disorder: Daily liquid methadone dispensed at SAMHSA-certified Opioid Treatment Programs (methadone clinics). Patients typically dose 60-120 mg daily.
- Pain management: Tablet methadone (5-10 mg) prescribed by physicians for chronic pain, less commonly.
Texas operates approximately 80 OTPs, with multiple clinics in Dallas-Fort Worth, Houston, San Antonio, and Austin metro areas. OTPs are federally regulated (42 CFR Part 8) and state-licensed by the Texas Health and Human Services Commission.
Why methadone is tested separately
Methadone does not appear on standard opiate panels because it is a synthetic opioid with a different chemical structure than morphine, codeine, or heroin. Standard 5-panel and 10-panel tests miss methadone. Detection requires a specific MTD panel.
Methadone also has a metabolite — EDDP (2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine) — that is sometimes tested alongside MTD. EDDP confirms methadone metabolism (rather than direct tablet adulteration), supporting the authenticity of the positive result.
Standard 12-panel and 13+ panel testing typically includes both MTD and EDDP. Texas drug court, federal probation, and opioid-related cases use these expanded panels.
Documenting methadone treatment
If you are on methadone maintenance and on Texas probation:
- Provide OTP enrollment documentation at probation intake. Letter from the OTP clinic confirming enrollment, dose, and program duration.
- Notify your probation officer before any test. Some officers require advance notification; some require monthly OTP attendance verification.
- Coordinate take-home dosing. Most OTPs require daily attendance initially; "take-home" doses are earned after demonstrated compliance. Texas probation officers may require attendance documentation.
- Update on dose changes. Significant dose changes should be reflected in your probation file.
- Document any deviations. Missed doses, transitions to other MAT, or program graduation should all be reported to probation.
Methadone without authorization — the violation case
A positive MTD result without OTP enrollment or prescription documentation is a serious violation. Texas Health & Safety Code §481.117 makes possession of methadone (Penalty Group 3) a Class A misdemeanor (less than 28 grams) up to first-degree felony (400 grams or more). Most diverted-methadone probation cases involve small amounts — still misdemeanor possession, plus probation violation.
Diverted methadone typically comes from:
- OTP patients selling or sharing take-home doses
- Pain-management methadone tablets diverted from valid prescriptions
- Illicit imports (rare)
Texas probation officers treat diverted-methadone positives more seriously than diverted-Suboxone positives because methadone overdose risk is higher (longer half-life, narrower therapeutic window). The path forward is the same: immediate consultation with counsel, transition to authorized MAT if appropriate, and aggressive treatment engagement.

Frequently Asked Questions
What does MTD mean on a drug test?
Methadone. MTD is the panel abbreviation for methadone testing, typically with a cutoff of 300 ng/mL on screening and 100 ng/mL on confirmation.
Will methadone show up on a standard probation drug test?
Only if MTD is on the panel. Standard 5-panel and 10-panel tests do not detect methadone. 12-panel and expanded panels include MTD (and often EDDP, the methadone metabolite).
Can I be on methadone maintenance while on Texas probation?
Yes, with documentation from a SAMHSA-certified Opioid Treatment Program (OTP) and authorization from your probation officer. Document enrollment, dosing, and attendance proactively.
What is EDDP on a drug test?
EDDP is the major methadone metabolite. Its presence confirms that methadone was metabolized by the body (rather than added to the sample as tablet adulteration), supporting the authenticity of a positive MTD result.
How long does methadone stay in urine?
Detection window: 3-7 days after last dose for most users. Chronic high-dose users can test positive longer. Hair testing extends detection to 90 days.
