Motivational and Behavioral Economics Informed Intervention for Cannabis Use

This trial explores new ways to help people who use cannabis by focusing on patient-centered outcomes. It compares two approaches: regular care and a combination of motivational techniques with behavioral economics, which examines decision-making. The goal is to determine which method better supports individuals in changing their cannabis use habits. Individuals who currently use cannabis regularly and have access to a phone or computer might be suitable for this trial. As an unphased trial, this study offers a unique opportunity to contribute to innovative research that could shape future cannabis use interventions.

Research has shown that behavioral treatments, like the one in this trial, are generally safe. Studies have found that these methods can help people reduce cannabis use without causing serious side effects. A review of several trials found that participants handle these treatments well. Most people experience only minor issues, mainly related to the difficulty of changing habits rather than the treatment itself. The goal is to help people make healthier choices, which usually doesn’t lead to harmful effects. Thus, this treatment appears safe for those interested in joining such trials.¹²³⁴⁵

Researchers are excited about the Motivational and Behavioral Economics Informed Intervention for cannabis use because it combines motivational interviewing with principles from behavioral economics, which is different from most current treatments like cognitive-behavioral therapy and contingency management. This approach aims to reduce cannabis use by enhancing personal motivation and leveraging economic principles to influence decision-making. By integrating these elements, the intervention offers a novel way to address the psychological and behavioral aspects of cannabis use, potentially leading to more effective and sustainable outcomes.

This trial will compare two approaches: the Motivational and Behavioral Economics Informed Intervention (MI-BE) and Enhanced Usual Care (EUC). Studies have shown that motivational techniques and strategies from behavioral economics, similar to those in the MI-BE arm, can help people reduce cannabis use. In one study, participants who received this approach were more likely to stop using cannabis, with 74.6% reducing their use compared to 63.9% in a group without the intervention. Another review found that combining motivational enhancement therapy (MET) with cognitive behavioral therapy (CBT) significantly decreased cannabis use frequency. These therapies change how people think about and respond to their cannabis use. This evidence suggests these methods can effectively help those who want to cut down or quit using cannabis.¹³⁶⁷⁸
