Digital interventions for substance use disorders (SUDs) have been around for a long time and are constantly being upgraded. That’s why I was glad to see a new review out of Brazil evaluating all the scientific studies done between 2014 and 2024 on the effectiveness of using recovery apps for alcohol use disorder, cannabis use disorder, opioid use disorder, and nicotine use disorder.

The bottom-line result is: They work! “Digital interventions demonstrated positive impacts on smoking cessation, contingency management for opioids, and reduction in alcohol and cannabis use,” write the authors. Now let’s take a look behind the scenes to see which interventions worked best, and why.

Alcohol Use Disorder

The use of recovery apps for alcohol use disorder (AUD) has an acceptance rate of about 65% among patients. The apps are more effective when they are customized for specific populations, such as veterans, and personalized with a “user-centered design.”

Researchers credit “digital peer-support communities” with cutting average alcohol consumption in half, from 37 drinks per week to 17.5. They highlight SoberGrid as an “emotional coping resource during periods of vulnerability.”

The researchers also acknowledge the Step Away app, which uses goal-setting and personalized feedback to keep people in recovery on the right track. The app has been shown to reduce binge drinking by 35% and average daily alcohol consumption by 65%. They also singled out the Drink Less app for “significant reductions in weekly alcohol consumption.”

Cannabis Use Disorder

The researchers found that digital interventions were effective against cannabis use disorder (CUD), cutting the number of days of use by as much as 33%. They found that digital intervention was useful “for adults who avoid formal treatment.” Among women, the HAP digital recovery application was preferred 2-to-1 over conventional treatment.

Nicotine Use Disorder

There were some very encouraging results among the nicotine use disorder (NUD) recovery apps. “Clinical trials of the Quit Genius application reported abstinence rates of up to 44.5% during the first month,” the researchers wrote, noting that the app “maintained significantly higher abstinence rates through week 52 compared with usual care.”

The researchers credited “gamification elements and automated behavioral support” for application success. They ended their review of stop-smoking apps with this intriguing statement:

Engagement with theory-based content within these applications has been identified as a key factor in promoting smoking cessation and reducing tobacco consumption.

Theory-based content? What could that mean?

Opioid Use Disorder

Digital interventions can help break bad habits and reduce consumption of harmful substances, but can they work against addictions to opioids and methamphetamines? “Yes,” say researchers, who also say the apps “have demonstrated effectiveness in supporting recovery and enhancing treatment retention.”

In particular, they cite digital contingency management programs, which have proven to be effective at keeping people in recovery for opioid use disorder (OUD) by offering rewards for attending counseling sessions and/or submitting clean lab tests.

The review mentioned three apps in particular that had achieved statistically significant improvements in the treatment of OUD: WeConnect, HOPE, and S-Check.

Designing Digital Interventions for Substance Use Disorder

The researchers made concluding remarks about the features that resulted in some digital interventions working better than others. Their thoughts:

• Mobile apps support patients between face-to-face visits
• mHealth apps foster “greater autonomy in self-management of the condition”
• 95% of the people in treatment for recovery interacted daily with their app
• Digital tools for substance use monitoring scored 81 out of 100 in usability
• Recovery apps resulted in improved communication with healthcare providers

Researchers concluded that recovery apps “enable just-in-time interventions grounded in cognitive-behavioral therapy (CBT) and mindfulness, optimizing craving management and relapse prevention.” That’s a promising evaluation for the potential of digital interventions to generate significant results when combined with professional guidance. These apps should reduce the cost and increase the effectiveness of treatments for SUDs.
