This directory lists 3 licensed treatment programs in Portsmouth, New Hampshire, drawn from the federal treatment services record (September 2026). Of those, 1 provide medical detox, 1 offer inpatient rehab or residential treatment and 3 run outpatient treatment.
Detox manages withdrawal safely and usually lasts a few days to a week; rehab is the treatment that follows, where therapy and medication address the substance use itself. Most people move from detox into inpatient rehab or an outpatient program, and the levels of care guide explains how each step works.
Cost depends on the level of care and how long you stay, and federal parity law requires most plans to cover addiction treatment on the same terms as other medical care. In Portsmouth, New Hampshire, 3 of the 3 listed centers report accepting private health insurance and 2 report a sliding fee scale based on income. The federal record lists payment types rather than named carriers, so call the center to confirm your insurance coverage.
Medical detox typically runs three to seven days, residential treatment commonly runs 30 to 90 days, and outpatient treatment can continue for several months. Research summarized by the National Institute on Drug Abuse finds that staying in treatment for at least 90 days across all settings is associated with better outcomes.
Withdrawal symptoms depend on the substance, how much was used, and for how long, and alcohol and benzodiazepine withdrawal can be medically dangerous without supervision. Our withdrawal timeline page sets out what typically happens day by day, and anyone with a history of seizures or heavy daily drinking should speak to a clinician before stopping.
Yes — programs that treat co-occurring disorders address substance use and conditions such as depression, anxiety or PTSD at the same time, which SAMHSA identifies as the recommended approach.
