Statistics show that success for addicts increases when the individual participates in a drug rehab program. The type of program that works best differs from person to person, based on the individual’s needs. Inpatient treatment has greater success for people with a long history of abuse because they learn the coping skills necessary to re-enter society. Outpatient treatment works best for people with a recent history of addiction. However, people that try to quit on their own or use medically assisted detoxification with no additional therapies from a drug addiction treatment center have the same success rate as those who were never treated at all—which is a very low success rate. The reason that treatment, whether inpatient or outpatient drug rehab, works is because after 3 months, improvements can be seen from the detoxification to relearning coping skills.
