Greenwood, a city with a total area of 42.62 km² of which 0.72% is water, is the county seat of Greenwood County. Greenwood had a population estimated at 23,407 as of 2018, a number enough to put the city into consideration as a possible home to a few people suffering from opioid use disorder. People who want to treat opiate dependence in this city may seek medical assistance at any Greenwood methadone Clinic. Although methadone clinics are specialists in the dispensing of medication for medically treated opiate addiction, some methadone clinics in South Carolina offer more services. Methadone is one of the three approved medications for the treatment of opioid addiction. The drug is an agonist that does not only block the negative effects of opioids but reduces cravings. The effects of methadone are long-lasting. They could be felt for up to 36 hours but the medication-assisted treatment professional may provide more doses of methadone within those hours. The opioid treatment program is tailored for individuals. Doses are prescribed after consideration of the complete health history of the program enrollee. Treatment with methadone is optional. Program enrollees have to be told the health risks of the program, after which they may decide to commence maintenance.
