Attending and completing a residential long-term treatment (more than 30 days) program in Lerna is often the cornerstone in an addict's successful recovery from their particular struggles with drug and alcohol addiction. This kind of drug rehabilitation is more intensive than others because 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 comprehend the good benefit. A residential long-term treatment (more than 30 days) program supplies the recovering individual the time to totally withdrawal from drugs and concentrate on themselves. Shorter programs are not capable of this due to their brief duration.
