Many Americans are aware of the United States’ current overdose and addiction epidemic. For patients, families, friends, and loved ones, the tragic health and behavioral effects of substance use disorders (SUDs) are readily recognizable at a level of intimate, granular detail. Among individuals who have used substances, not all have SUDS, but many have spent money on illicit substances. SUD-related discussions frequently focus on survival or addiction, sometimes looking past another elephant in the room: finance. A recent RAND report for the Office of National Drug Control Policy (ONDCP) sheds an important light on how much money we pay for illegal drugs by highlighting Americans’ expenditures on methamphetamine, marijuana, heroin, and cocaine.
