Frequently Asked Questions

Length of Long-Term Drug Rehab

Residential
Longer stay in a structured, home-like environment to rebuild routines and life skills. You live on-site with staff and peers in recovery, following a daily program focused on long-term change.
2–12 months

Research published by the National Institute on Drug Abuse (NIDA) shows that people who stay engaged in treatment for at least 90 days achieve significantly better recovery outcomes. While every person’s path is different, the data consistently suggest that longer participation—whether through residential, outpatient, or continuing care—leads to stronger, more stable results.

From 2015 to 2017 he worked as a Withdrawal Specialist at a residential treatment facility, sitting with patients through the most physically and emotionally difficult days of early recovery. From 2017 to 2019 he served as Director of Rehabilitation, overseeing patient case management, coordinating with staff, and working with families through every stage of treatment. Before entering the field, Michael went through his own recovery, with four treatment attempts before the fourth one took hold. That lived experience layered on top of his clinical years informs how he approaches every topic he writes about.
