Does methadone treatment impair mental function?

Methadone treatment has no adverse effects on intelligence, mental capability or employability. Methadone treated patients are comparable to non-patients in reaction time, in ability to learn, focus and make complex
judgments. Methadone treated patients do well in a wide array of vocational endeavors, including professional positions, service occupations and skilled, technical and support jobs.

Why do drug-addicted persons keep using drugs?

Nearly all addicted individuals believe at the outset that they can stop using drugs on their own and most try to stop without treatment. Although some people are successful, many attempts result in failure to achieve long-term abstinence. Research has shown that long-term drug abuse results in changes in the brain that persist long after a person stops using drugs. These drug-induced changes in brain function can have many behavioral consequences. including an inability to exert control over the impulse to use drugs despite adverse consequences-the defining characteristic of addiction.   

Is the use of medications like methadone and buprenorphine simply replacing one drug addiction with another?

No – as used in maintenance treatment, buprenorphine and methadone are not heroin/opioid substitutes. They are prescribed or administered under monitored, controlled conditions and are safe and effective for treatment
opioid addiction when used as directed. In contrast, methadone and buprenorphine have gradual onsets of action and produce stable levels of the drug in the brain; as a result, patients maintained on these medications do
not experience a rush, while they also markedly reduce their desire to use opioids. If an individual treated with these medications tries to take an opioid such as heroin, the euphoric effects are usually dampened or suppressed. Patients undergoing maintenance treatment do not experience the physiological or behavioral abnormalities from rapid fluctuations in drug levels associated with heroin use. Maintenance treatments save lives – they
help to stabilize individuals, allowing treatment of their medical, psychological and other problems so they can contribute effectively as members of families and of society.  

Does Methadone Hurts Your Health? 

The health status of methadone patients has been studied more frequently than other medications.
There is no scientific evidence that methadone rots teeth, gets into bones, or causes any other health issues. Extensive drug abuse can lead to neglect of personal hygiene, which can cause health issues. Taking methadone is safe for expectant mothers.

Do People Get High On Methadone?

Methadone is an opiate blocker, which means that it blocks the craving for opiates once the methadone is ingested.
The "blocking" effect of methadone helps the individual "normalize" their life again. The "blocking" effect lasts for 24 hours, so the individual will have an opportunity to "unravel" the addict way of thinking. Once an individual is taking the appropriate dosage, there is no impairment of motor skills or thinking ability (as long as no other psychoactive drugs are taken with it).
