Attending and completing a residential long-term rehabilitation (more than 30 days) program in Calvin is usually the cornerstone in an addict's successful recovery from their individual struggles with drug and alcohol addiction. This form of drug treatment is far more intensive than others due to the fact the individual lives at the facility full-time through the treatment process. While many addicts are at first hesitant about attending a long-term program lasting longer than 30 days they soon notice the fantastic benefit. A residential long-term treatment (more than 30 days) program provides the recovering individual the time to totally withdrawal from drugs and focus on themselves. Shorter programs are not capable of this due to their short duration.
