Having just arrived at the psychiatry department, I had the opportunity to observe the methadone substitution clinic, listened to the attending physician's teaching, and organized some reflections.
The methadone clinic provides an substitution therapy for opioid addiction, aiming to reduce the harm of such drugs through methadone's lower toxicity, lower euphoric addiction potential compared to heroin, and related government control measures.
Overall, the methadone substitution clinic can reduce the relapse rate of drug use. According to statistics, although drug users will be imprisoned according to the law, the recidivism rate after release is still very high. Providing methadone can reduce the proportion of returning to opioid drug use.
According to the teaching physician, the advantages of the methadone clinic in various aspects include:
- Reducing the financial burden on addicts: Taking heroin as an example, if an addict spends about three thousand NT dollars a day on its trade, the monthly cost is over ninety thousand NT dollars, which is absolutely a huge financial burden. In addition, the frequent symptoms and side effects of addicts affect their work, making drug addicts prone to take the wrong path and implicitly increasing social risks. Although the methadone clinic is not covered by national health insurance, most local governments offer subsidies, encouraging addicts to strive for them with good attendance rates. The monthly cost is just over NT$100 a month, and even without any subsidies, it is only about over four hundred NT dollars, far less than the financial burden of the drug black market.
- Decreasing the rate of drug reuse: Due to its pharmacological properties, methadone does not produce the same "high" as heroin. Even if one uses methadone and then goes back to using heroin, the effect of heroin will be diminished, greatly reducing the drug's appeal. Addicts have less incentive to choose expensive drugs again.
- Reducing the risk of cross-infection of diseases: Most opioids like heroin are used via injection, making needle hygiene a crucial issue. Methadone is administered orally. Once drug addiction is successfully replaced, it not only avoids the risk of cross-infection from needles—such as blood-borne diseases like HIV and Hepatitis B and C—but also prevents bacterial infections like cellulitis caused by improper disinfection. Some patients referred to the methadone clinic are HIV cases reported by the Centers for Disease Control (CDC), aimed at lowering societal risks. (This will be mentioned again later.)
- Helping addicts reintegrate into life: Drug addiction easily leads to social alienation (think about it: if you constantly borrow money from relatives and friends and have no ability to repay, who would want to associate with you?) and other life issues. Through the methadone substitution clinic, the hope is to help addicts establish a regular life, minimize the harm addiction causes to their lives, and enable patients who originally could hardly manage their lives to work normally and participate in social activities.
Although national health insurance does not cover it, most local governments in Taiwan actually have encouraging subsidy measures. If patients maintain a high attendance rate and follow the rules during the methadone substitution clinic treatment, they can apply for subsidies. The government uses subsidies to increase the incentive for methadone substitution clinics. At the same time, the legal community is gradually accepting the concept of substituting treatment for punishment. When considering whether to indict opioid drug users, many prosecutors will also give addicts the opportunity to choose the methadone clinic, exchanging good behavior during the clinic treatment for deferred prosecution, leaving only a criminal record.
In addition to legal cases, there are also cases referred by the Centers for Disease Control (CDC), which might be patients with drug addiction who have HIV or other severe diseases that can be transmitted through shared needles. The purpose of the CDC referring these cases is because methadone is taken orally; once substitution is successful, the transmission route of sharing needles during withdrawal can be eradicated, lowering societal risk.
In the methadone clinic, one may also encounter borderline legal issues. If a patient reveals that they couldn't withstand the withdrawal symptoms during treatment and secretly went back to injecting, should the police be called? I feel this actually shares similar contextual considerations with the recent incident where police disguised themselves as social workers to arrest a criminal. The role of the physician requires establishing a certain degree of trust with the patient, and through this relationship, counseling and helping the patient escape the clutches of drugs as soon as possible. If this relationship is rashly destroyed, it will interrupt the current treatment course, delaying what might be the patient's first or last chance in their lifetime to break free from drugs, and potentially undermining the stance of the methadone clinic in corners of society. Within the drug-addicted population, interpersonal networks are more or less interconnected. When this channel of the methadone clinic is no longer trusted by the drug-addicted community, overall drug prevention efforts will be impacted.
First-time patients at the methadone clinic require significant effort to evaluate, including drug usage status, liver function, and kidney function tests, while also educating patients on essential knowledge. Some patients mistakenly believe that methadone is similar to a hangover remedy and that taking methadone after using opioids can clear the drug's toxicity. Such misunderstandings easily lead to drug overdoses. Excessive use of opioid drugs can result in pinpoint pupils, acute respiratory depression, and even death, which is highly dangerous.
Because methadone is a controlled substance, there is a rigorous management process at the methadone clinic. There is an island-wide patient database to prevent duplicate drug dispensing, and it must be dispensed and consumed on the spot. Dispensing staff must watch the patient to ensure it is completely swallowed, allowing no opportunity for the patient to take it out of the clinic. Furthermore, at National Cheng Kung University Hospital, for example, the total amount of the drug is strictly controlled. From the drug storage area to the clinic transport, it is monitored by security personnel, absolutely not giving outsiders any chance to steal and sell it illegally.
