There are different types of addiction rehab that can be effective in treating substance use disorders. Some of these include contingency management, outpatient counseling, and inpatient rehabilitation. The National Institute on Drug Abuse(NIDA) supports research to develop safe and effective treatment strategies for long-term recovery. The cost-benefit ratios of different types of prevention policies and programs are also discussed in some resources. It is important to note that the effectiveness of addiction rehab can vary depending on the individual and their specific needs, and a personalized treatment plan is often the most effective approach.
