A new study that looks at the long-term costs of addiction finds heroin, oxycodone and cocaine rank as the top three most expensive substances. Each addiction costs more than a million dollars to support over a 50-year period, CNBC reports.
The average five-year cost for using heroin 10 times a day is $318,500. For oxycodone (80 milligrams once a day), the five-year cost is $132,405. For cocaine (1 gram once a day) the five-year cost is $112,840.
