Drug & alcohol rehab centers in Wilmington, DE

Our directory is built to help you compare treatment options in Wilmington with confidence. Listings are organized to surface facilities that hold recognized accreditation, maintain current state licensing and offer verified levels of care, so you can focus on programs that meet established standards of quality and safety.

We prioritize facilities based on the completeness and accuracy of their program information, the range of services and levels of care they provide, accepted payment types and insurance and third-party accreditation from bodies such as the Joint Commission and CARF. We do not accept payment in exchange for a higher position in these results.

When details cannot be independently verified, we note the gap rather than assume it. This approach is meant to give you a clear, honest starting point as you research choosing a rehab center that fits your needs.

Wilmington is the largest city in Delaware and the seat of New Castle County, the most densely populated of the state's three counties. The Delaware directory of rehab centers reflects a treatment system concentrated heavily in this northern part of the state, and the city itself sits at the center of both the region's provider network and its overdose burden.

There are 28 treatment facilities in the Wilmington directory, spanning medical detox, residential care and community-based outpatient services.

New Castle County carries the heaviest share of Delaware's substance use crisis. In 2024, the county recorded 222 fatal drug overdoses, more than 65% of the statewide total, according to data reported by Delaware Health and Social Services. Additionally, Wilmington ZIP codes have consistently shown the highest rates of non-fatal overdose emergency visits in the state.

Fentanyl is the dominant driver and was detected in more than 80% of Delaware's accidental overdose deaths. The animal tranquilizer xylazine has also increasingly contaminated the local drug supply, complicating both overdose response and withdrawal. For anyone weighing options, understanding the range of addiction treatment options available locally is a practical first step.

The Delaware Division of Substance Abuse and Mental Health (DSAMH) anchors publicly funded care in the city, contracting with private agencies for screening, outpatient counseling, opioid treatment, detox and residential services.

Wilmington is also home to long-standing community providers such as Brandywine Counseling and Community Services, which operates opioid treatment and harm reduction programs, and to grassroots organizations like atTAcK addiction, which focus on naloxone training, education and recovery housing.

Because fentanyl accounts for so much of the local harm, many residents begin by researching fentanyl addiction and overdose risk and the treatment pathways that address it.

Treatment costs in Wilmington vary widely by level of care, program length and the services included. There is no single published figure for the city, so the most reliable anchor is Delaware's statewide averages.

Wilmington is the state's largest urban market. It is located in the county with the highest cost of living; as a result, prices at private programs here tend to be at or above state averages, though publicly funded and nonprofit options can lower out-of-pocket costs substantially.

These figures represent full program costs before insurance, financial assistance or sliding-scale adjustments. Most people pay a fraction of these amounts once coverage is applied.

The difference between residential treatment and community-based outpatient care is often the single largest factor in total cost, which is why many Wilmington residents step down from a short residential or detox stay into ongoing outpatient support. Several factors shape the final price:

Checking your coverage is the fastest way to narrow the field. A short call to your insurer or a treatment provider can clarify what a specific program will actually cost you before you commit.

Of the 28 facilities listed in Wilmington, most accept more than one form of payment and many work with public coverage that removes cost as a barrier entirely. The counts below reflect how many local facilities accept each payment type, based on the current directory.

The right payment path depends on your coverage and circumstances. The subsections below outline the most common options in Wilmington.

Wilmington offers a full continuum of care, from medically supervised detox through long-term outpatient support. The directory includes 9 detox providers, 16 inpatient programs and 24 standard outpatient clinics, alongside partial hospitalization and dual diagnosis options.

Medical detox is often the first step for people with physical dependence on alcohol, opioids or benzodiazepines. Because xylazine has entered the local opioid supply and can complicate withdrawal, supervised medical detox is especially important for Wilmington residents using street opioids. Detox stabilizes the body safely but is not treatment on its own, just a bridge to ongoing care.

Inpatient and residential rehab provides 24-hour structured care, typically over 30 to 90 days, and suits people with severe substance use disorders or unstable home environments. Wilmington's 16 residential treatment programs offer a higher-intensity setting away from daily triggers.

Partial hospitalization programs deliver intensive daytime treatment while allowing clients to return home in the evening, serving as a step down from residential care or a step up from standard outpatient. The city's 3 partial hospitalization programs fill this middle tier.

Outpatient care is the most widely available level in Wilmington, with 24 clinics offering everything from weekly counseling to intensive outpatient schedules. Intensive outpatient programs let people maintain work, school, and family responsibilities while receiving structured treatment, and are frequently paired with medication for opioid or alcohol use disorder.

Dual diagnosis programs treat substance use and co-occurring mental health conditions together, which matters given how often addiction overlaps with depression and anxiety. Twenty Wilmington facilities offer integrated care for people also managing conditions such as co-occurring depression.

Sober living homes provide substance-free housing during and after formal treatment. New Castle County holds the largest share of Delaware's recovery residences. These homes support the transition back to independent life. Planning for this stage is part of effective rehab aftercare.

Many Wilmington facilities tailor care to specific populations, recognizing that effective treatment accounts for a person's age, background and life circumstances. The counts below reflect programs in the local directory serving each group.

Alcohol remains one of the most common reasons Wilmington residents seek care, with 24 programs treating alcohol use disorder. Given fentanyl's role in local overdoses, the 17 programs focused on opioid use disorder are also central to the city's response.

Programs designed for younger adults address the specific pressures around young adult and college student substance use, while 6 facilities provide LGBTQ+ affirming addiction care and 4 offer programming built around the needs of veterans and military families through rehab resources for veterans and military.

Cost should never be the reason someone in Wilmington goes without help. A network of state agencies, nonprofits and harm reduction programs provides free or low-cost support, from 24-hour crisis lines to naloxone distribution and publicly funded treatment.

Wilmington and New Castle County carry a disproportionate share of Delaware's overdose crisis, though the most recent data also shows meaningful progress.

Statewide, fatal overdoses fell 36% in 2024 to 338 deaths, down from 527 the year before, the largest single-year decline in the state's history and a drop public health officials attribute in large part to widespread naloxone distribution. New Castle County, home to Wilmington, still accounts for the majority of the state's fatal overdoses.

Wilmington ZIP codes reported the highest rates of suspected opioid overdose emergency visits in the state, ranging from 272 to 658 per 100,000 residents, according to DHSS quarterly briefing data. Alcohol also remains a significant concern statewide, with roughly 1,935 Delawareans admitted for treatment where alcohol was the primary or a secondary substance in recent reporting.

These figures underscore why access to opioid treatment and harm reduction services is a priority across the city. For national context, see our overview of national substance use statistics.
