Methadone is a synthetic opioid commonly used by those trying to ween themselves off heroin, whose effects it partially mimics. While those who use methadone during heroin detoxification can expect some side effects, insanity is not reported to be among them.

Function

Methadone is also commonly used an an analgesic to relieve pain. According to "The Treatment of Opioid Dependence," this can cause some sedation during early use. The effect does not last, however, and should not be confused with a permanent debilitating mental condition.

Effects

According to "The Side Effects of Drugs," by Jeffrey Aronson, neurological side effects of methadone can include episodic memory deficits, temporary movement disorders and some spasticity, but no permanent cognitive disorders, including insanity.

Misconceptions

There has been some misconception that methadone causes hallucinations. According to the Consumers Union, in a study of 207 methadone patients, 17 reported hallucinations. However, the union also reports that study's methology was criticized and no independent verification has been made of the claims.

Expert Insight

Aronson, the Consumers Union and the authors of "The Treatment of Opioid Dependence" all conclude that, while methadone can cause several neurological side effects, it does not cause insanity in any form.

Benefits

According to "The Treatment of Opioid Dependence," most people who use methadone to ween themselves off heroin are successful, at least temporarily.
