Columbia, a census-designated place in Howard County, has a total area of 83.4 km². Some methadone clinics could be found in Columbia. Considering its estimated 2015 population of 103,467, the city has a high probability of being home to a number of residents who are suffering from opioid use disorder. Such residents may contact a medication-assisted treatment expert at any Columbia methadone clinic. Medication-assisted treatment experts dispense medication for the treatment of opiate dependence. They could choose between three approved drugs, one of which is methadone. Medication-assisted treatment practitioners do not only prescribe doses of methadone, but they require their patients to enroll for behavioral therapies to correct both the physical and psychological effects of opioid use disorder. Methadone blunts the effects of opioids but it does not cause negative effects. Depending on the health history of the program enrollee, methadone may have some side effects but they would be managed the right way by a health provider. Some of the best methadone clinics in Maryland offer additional medical and social services. Doses of methadone are tailored for individuals. The medication-assisted treatment professional gives the patient exactly what is needed. Treatment occurs under the close observation of the health provider but after some months, patients who display some level of stability may be allowed to take it between program visits at home.
