Callaway is located in St. Mary’s County. It has a population estimated at 1,401. It could be one of the smallest places in the U.S but its number does not rule out the possibility that it could be home to a few people experiencing opioid use disorder. Such people in the location or nearby cities may visit any Callaway methadone clinic for medication-assisted treatment. People experiencing opioid disorder find it difficult to stop despite the negative effects that opioids cause. The situation is difficult because opioid relieves pains and gives euphoria but its effects are short-term which are immediately followed by uncontrollable craving and possibly pain in the long run. The Food and Drug Administration approved methadone for the treatment of such conditions because it replaces opioids in the body without having negative effects. Not only does it last longer than opioids, but it also blunts the effects of opioid use and its withdrawal symptoms. Methadone, because of how fast opioid use disorder has spread, has now become a vital medication which has resulted in its inclusion on the World Health Organization’s list of essential medications. Patients who are undergoing methadone maintenance are encouraged to partake in behavioral therapies too. Most methadone clinics in Maryland have an existing setup to offer this.
