AKA: 30-Day Program
A residential rehab model with a planned stay of around 28–30 days, traditionally popular in many treatment systems.
In the context of addiction treatment:
This length became standard largely due to insurance and historical patterns, not because it’s the “magic number” for everyone.
What to know:
-
Useful for initial stabilization, detox, education, and starting a recovery plan.
-
Many people need ongoing care afterward (IOP, outpatient, sober living, MAT).
-
Shorter than ideal for more severe or long-standing addiction, but still better than no structured care.
Example:
A person completes a 28-day inpatient program, then continues in an 8-week IOP and moves into sober housing.
