Enhancing Prospective Thinking in Early Recovery

The goal of this clinical trial is to use a novel virtual reality intervention to test for efficacy in reducing stimulant use and increasing abstinence, with concomitant increases in future self-identification, future time perspective, and delay-of-reward, in early recovering stimulant use disorder (StUD) persons. The main question\[s\] this trial aims to answer are: * Will the Virtual Reality (VR) intervention decrease the number of stimulant use days? * Will the VR intervention produce longer abstinence periods during follow-up visits? * Will the VR intervention increase stimulant drug abstinence rates? * Will the VR intervention increase future self-identification? * Will the VR intervention increase self-reported future time perspective? * Will the VR intervention increase preference for delayed rewards in a laboratory delay discounting task on the study day? * Will the VR intervention produce gains in the behavioral effects of future self-identification, future time perspective, and delayed rewards at the 30-day and 6-month follow-ups? Researchers will compare the experimental and control groups to see if there are differences in the results for the questions outlined above.
