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