Notes: Cost estimates presented in 2008 dollars. Standard deviations are in parentheses. Reductions in societal costs (i.e., total savings) were calculated as the monetary value of reductions in days of illegal activity, days experiencing medical problems, days experiencing psychiatric problems, and days in jail captured with the Addiction Severity Index (ASI). Net savings were calculated by subtracting intervention costs (with and without client costs) from total savings. The societal cost per day experiencing medical problems is $25.25; per day experiencing psychiatric problems is $10.22; per day engaging in illegal activity is $998.41; and per day incarcerated is $60.35.
