Choosing Money over Drugs: The Neural Underpinnings of Difficult Choice in Chronic Cocaine Users
Figure 4
Money and cocaine choices. Data are the averaged (±SEM) percentages of immediate (now) and future (later) choices in controls (Controls) chronic cocaine users (CCUs). Single-commodity choice involved choosing between immediate or future money (MM) or cocaine (CC), and cross-commodity choice involved choosing between immediate money and future cocaine (MC) or between immediate cocaine and future money (CM). Money and cocaine choices are green and red, respectively. CCUs made fewer choices for future money, compared to Controls (MM and CM). In cross-commodity tasks, CCUs chose cocaine more than Controls. Regardless, a large portion of the choices were for money (MC = 65% and CM = 50%). Incentivizing the future with money resulted in a 15% increase in future choices in CCUs away from the immediate cocaine option (MC = 35% versus CM = 50%). *Difference between groups, within task, ; #difference, within group, between cross-commodity tasks, .
