“…In forced‐choice laboratory studies offering the immediate opportunity to use crack cocaine or receive monetary reward, addicts frequently choose money over drugs (Hart, Haney, Foltin, & Fischman, 2000). In addition, contingency management treatment is highly effective (for a review see Zajac, Alessi, & Petry, 2018) offering positive rewards contingent on drug‐free urine samples in the form of money, prizes, and most recently and successfully, employment (Silverman, Holtyn, & Morrison, 2016); rates of use are cost‐sensitive (Ainslie, 2000); and correctional services can succeed in establishing abstinence by imposing costs for failure (Hawken & Kleiman, 2009; Levy, 2013). Lastly, large‐scale epidemiological data suggest that the majority of people meeting criteria for SUD (including those with physical dependence) recover without clinical intervention by their late 20s or early 30s (Heyman, 2009) – and of course, anecdotal (Heyman, 2009) and clinical (Pickard & Pearce, 2013) stories abound of people going “cold turkey”.…”
