Sober Nation lists 136 treatment centers across Louisiana, and they cluster where the people are. Baton Rouge leads with 15 centers and New Orleans follows with 13; Monroe and Metairie list 8 each, and Shreveport and Lafayette 7 each. Beyond those hubs the numbers thin quickly. Lake Charles has 4, and New Iberia, Slidell, and Mandeville list 3 apiece, which means that across much of the state, options are limited and some travel is part of the plan.
Those listings describe supply; they do not describe the need behind it. The number of Louisiana residents aged 12 and older who meet the criteria for a substance use disorder in a given year is estimated at about 753,000, or roughly one in five (19.8%), while only about 5.1% — some 192,000 people — receive any substance use treatment, the treatment gap that shapes so much of this work. Drug overdose deaths, still driven mostly by opioids such as fentanyl, have fallen sharply: Louisiana recorded 1,467 drug overdose deaths in 2024, about half of them (725) opioid-involved, and the Louisiana Department of Health reported that the state's drug-overdose deaths dropped by roughly a third from 2023 to 2024. Those figures are exactly why the service mix below matters: knowing what a center genuinely provides lets you reach real help faster instead of working down a phone list.
