When addiction disrupts life, time feels slippery. You want to know how long rehab takes and what each stage actually does. Here’s the clear answer: most drug rehab programs run 30 to 90 days, with options for long-term residential care that extend to 6 months or more when needed. The right length depends on your substance history, health needs, and support at home.
Overall, start where you can commit, then extend if your clinical team recommends it. Recovery is a process, not a stopwatch.
How Long Does Drug Rehab Last? A Quick Overview
Rehab length varies by program type and personal factors, but these guardrails help:
- Detox: 3 to 10 days for most substances, longer for certain cases
- 30-day inpatient: foundation setting, relapse-prevention basics
- 60-day inpatient: deeper therapy, stronger coping skills
- 90-day inpatient: best for severe or long-running addiction, dual diagnosis
- Long-term residential, 6 to 12 months: full reset with life skills and community
- Outpatient care: weeks to months, often after inpatient or as a step-down plan

Program Types and Typical Durations
Here are the types and typical durations for Drug Rehab:
1) Medical Detox Timeline
Detox clears substances under medical supervision. Expect vitals monitoring, comfort meds when appropriate, and 24/7 care. Most detox phases finish within a week, but some cases require more time for safety and stability.
2) Inpatient Residential Care
You live in a structured setting with a full daily schedule.
- 30 days: assessment, stabilization, core therapies, relapse-prevention plan
- 60 days: added time to process triggers, trauma work, habit reset
- 90 days: evidence suggests stronger outcomes for complex histories and co-occurring disorders
3) Partial Hospitalization and Intensive Outpatient
You return home after sessions, but care stays rigorous.
- PHP: 4 to 6 weeks in many cases, several hours per day
- IOP: 8 to 12 weeks on average, multiple sessions per week
4) Long-Term Residential Programs
For chronic relapse or limited support at home. Expect 6 to 12 months with therapy, skill-building, peer community, and a slower transition back to daily life.
What Decides Your Rehab Length?
- Substance type and duration of use
- Withdrawal risks and medical needs
- Mental health needs (anxiety, depression, PTSD, bipolar)
- Relapse history and current triggers
- Support at home and stability after discharge
- Progress in therapy and readiness for the next level of care
Why 90 Days Often Wins
Change takes repetition. Programs that reach 90 days or more usually deliver stronger results because you get time to practice skills, face triggers with support, and lock in a follow-up plan. If 90 days feels hard, commit to 30 and reassess with your care team.
What You Learn While You Are There
- Detox support and safety
- CBT and other evidence-based therapies to change thought patterns
- Group therapy and peer support for accountability and connection
- Family therapy to reset boundaries and rebuild trust
- Holistic care such as mindfulness, movement, and nutrition
- Dual diagnosis treatment if mental health conditions are present
- Relapse-prevention skills with a concrete aftercare plan
Sample Timelines You Can Use

60 Days
Everything in 30 days plus deeper trauma work, stronger community ties, and more practice under supervision.
90 Days
Adds time for complex mental health needs, lifestyle rebuild, and real-world exposure with support before discharge.
Aftercare Extends Your Results
Recovery continues after the door opens. Strong programs set you up with:
- Outpatient therapy or IOP
- Peer meetings and sober community
- Medication-assisted treatment when appropriate
- Sober living for structure and safety
- Check-ins with your care team and relapse-prevention refreshers
Think of aftercare as the bridge from treatment to everyday life. The longer you stay engaged, the steadier your progress.
How To Choose The Right Length
- Be honest about your history and triggers.
- Ask for a full assessment that includes mental health.
- Start with the most support you can manage, then adjust.
- Prioritize programs that include aftercare, not just discharge.
Summing Up
There is no single right number of days. Most people benefit from 30 to 90 days, with longer residential care when needed, and a strong aftercare plan for the real world. Time in treatment is an investment that pays off every day you stay sober.
