Benefit-Cost in the California Treatment Outcome Project: Does Substance Abuse "Pay for Itself?"

I think I posted a news article summarizing these findings, but this link includes a PDF of the journal article:

Results from a cost-benefit analysis of substance abuse treatment programs are presented. Sections of this article include: abstract; methods; results according to per diem substance abuse treatment costs, average cost and benefits associated with substance abuse treatment, pre-post changes in the individual sources of monetary benefit, sensitivity analyses; "inflating" the arrest data, multiple regression models, cohort, and varying treatment intensity across providers; and discussion. A ratio of 7:1 benefits to costs exists; a benefit of $11,487 to a cost of $1,583.
