A research team led by Dr. Michael French gathered to estimate the costs and benefits of residential and publically funded treatment programs for addiction issues. The team was derived from the University of Miami. Program and the client related economic cost estimates were obtained using data collected at the site with the drug abuse treatment cost analysis program (DATCAP). It was concluded that the economic benefit to society was almost four times what the cost of treating residential clients. Short-term follow-up treatment was also beneficial and the economic benefit was even higher. Hanlon, T.E., Kinlock, T.W., Nurco, D.N. (1991).

The study reviews previous research on the correlation of drug use and criminal behavior resulting in arrest since 1980. Advances were noted in crime studies that included known drug abusers. This was also the case in studies of the drug use of those processed by the criminal justice system. Mostly the studies concluded that the criminal activity of narcotic abusers was higher and there was also a higher rate of crime associated with frequent use of cocaine or heroine. The addicts studied varied in the severity and type of criminal activity they were involved with. The effects of treatment and criminal justice interventions as well as other drug-related violence were included.

Lennings, C.J., Copeland, J., Howard J. (2003). "Substance use patterns of young offenders and violent crime." Aggressive Behavior. 29(5), 414-422. This study's hypothesis was that alcohol use is a significant predictor of violent crime in committed by the youth. Researchers studied 300 juveniles that had been incarcerated in the prison system of New South Wales. Of the 300, more than 70% admitted to having committed violent crimes. Most correlated with the onset of violent crimes was alcohol use followed...

The findings accounted for the correlation that exists between the use of substabce and aggressive, violent crime and so, further supported the "Goldstein hypothesis" which believes that substance abuse facilitates violent behavior directly.

Criminal Behavior and Mental Health, 7(4), 287-310. The report discussed the correlation of alcohol abuse, drug abuse, non-violent crime and violence concerning children who were abused and neglected during the course of their development through childhood. The study was longitudinal (the subjects were studied over time into adulthood). It was found that abused and neglected females and males have a higher correlation in substance abuse and non-violent arrest. Abused and neglected females were found to be at a higher risk for both drug abuse or dependency diagnosis as well as arrests for violent crime.

Zarkin, G.A., Dunlap, L.J., Hicks, K., Mamo, D. (2005). "Benefits and costs of methadone treatment: results from a lifetime simulation model." Health Economics. 14(11) 1133-1150. Research examined prior studies that included the cost and benefits of methadone abuse treatment. These papers have often been written on single case studies. While valuable to society, the sample size limitation also limits the research because they view heightened problems as being able to be treated in one incident of treatment. A simulation model was created to embody the longitudinal study of the heroine use, criminal behavior, health care and employment of a population between the ages of 18-60. It was found that the model (which takes into account the dynamics of heroine use and views it as a, acute and reoccurring circumstance) finds that the benefits of treatment using this model far outweigh those produced by static models.
