† The Substance Abuse and Mental Health Services Agency (SAMHSA), has set "cut-off" levels when testing for marijuana, cocaine, methamphetamine, amphetamines, ecstasy, opiates, and PCP. First Check is manufactured to conform to those standards. Screening tests may not detect amounts of drugs in a urine sample that are below the cut-off level. Even though some level of drug may be present in a urine sample, the sample would still be considered Negative Result if the drug level is below the cut-off level.


METHADONE


What is it?

Methadone is a prescription narcotic used in the treatment of opiate addiction. Methadone blocks the euphoric effects of heroin, reduces craving and suppresses withdrawal effects for more than 24 hours. Methadone is sometimes diverted from its legitimate use, sold on the illegal market, and used as a drug of abuse.

Slang Terms:

Juice, green, amidone, chocolate chip cookies (methadone or heroin combined with MDMA), fizzies, street methadone and wafer.

How is it used?

Methadone is available as a tablet, as an oral solution, or as an injectible liquid.

Side Effects of usage:

Side effects of methadone are sweating, sedation, constipation, and weight gain. After regular usage these side effects usually disappear.

How long do the effects last?

Methadone is typically administered on a daily basis under the supervision of a Methadone Clinic and its effects last for 24-36 hours. However, individuals are now abusing Methadone rather then using it as a means of recovery from Heroin.

Effects of withdrawal:

When a dependent user stops taking the drug they may experience withdrawal symptoms including muscle tremors, nausea, diarrhea, vomiting, abdominal cramps, sweating, and runny nose.

Adverse reactions:

Individuals who abuse methadone risk becoming tolerant of and physically dependent on the drug. Methadone does not produce the euphoric rush associated with other narcotics so there is the potential for users to consume dangerously large quantities of methadone in a vain attempt to attain the desired narcotic rush. Methadone overdoses are associated with severe respiratory depressions, decreases in heart rate and blood pressure, coma, and death.

Effects of prolonged usage:

Methadone has been proven to be clinically safe when prescribed and administered under medical supervision.

Usage by youth:

Nearly 1% of high school seniors in the U.S. reported abusing methadone at least once in their lifetime.

Recent Developments:

The increasing availability of illegal methadone has created new experimentation with the drug. Most common is combining methadone with other drugs such as ecstasy.
