Methadone maintenance programs--a two-edged sword?

Abstract:
Retrospective review was undertaken of all autopsies in which methadone was detected at the Forensic Science Centre, South Australia, during a 3-year period from July 1996 to June 1999. Thirty-five cases were found in which methadone had either caused or contributed to death (age range = 14-54 years; average = 31 years; M:F = 3.4:1). Ten victims were participating in a methadone maintenance program, of whom four died within a week of enrollment. Eight victims (23%) not enrolled in a methadone maintenance program were found who had died after the use of "diverted" methadone (i.e., prescribed for someone else) (age range = 14-34 years; average = 25 years; M:F = 6:2). Deaths were directly attributable to methadone toxicity in seven of the eight cases, with additional drugs or alcohol being found in seven cases. Prevention of ongoing deaths caused by methadone diversion could be achieved by allowing only daily releases of methadone, with the addict having to consume the drug under close supervision.
Insights
Methadone toxicity caused or contributed to 35 deaths in South Australia. Diversion of methadone, particularly among younger individuals, led to fatal overdoses, highlighting the need for supervised consumption.
Area of Science:
- Forensic Toxicology
- Clinical Toxicology
- Public Health
Background:
- Methadone is a widely used opioid agonist therapy for opioid use disorder.
- Methadone overdose and diversion are significant public health concerns.
- Understanding patterns of methadone-related deaths is crucial for prevention strategies.
Purpose of the Study:
- To review cases of death where methadone was detected in South Australia.
- To identify the role of methadone in contributing to or causing mortality.
- To analyze characteristics of individuals who died from methadone toxicity, including those involving diverted methadone.
Main Methods:
- Retrospective review of autopsy cases at the Forensic Science Centre, South Australia.
- Data collection period: July 1996 to June 1999.
- Inclusion criteria: Autopsies where methadone was detected and potentially involved in death.
Main Results:
- Thirty-five cases identified where methadone caused or contributed to death (age 14-54, average 31).
- Ten individuals were in methadone maintenance programs; four died within a week of enrollment.
- Eight individuals (23%) died from "diverted" methadone (age 14-34, average 25), with toxicity directly causing death in seven cases. Seven of these also involved other drugs or alcohol.
Conclusions:
- Methadone diversion is a significant cause of fatal overdose, particularly in younger populations.
- Supervised consumption and daily dispensing of methadone could prevent deaths related to diversion.
- Further interventions are needed to address methadone toxicity and misuse within maintenance programs and illicit use.

The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...
