From Cue Exposure to Situated Action: Immersive, Embodied, and Socially-Oriented Technologies for Alcohol Use Disorder.

Imagine a person struggling with alcohol use disorder standing at a crossroads. On one side is the familiar, heavy pull of a craving, triggered by the sight of a bottle, the noise of a crowded bar, or the pressure of a friend offering a drink. On the other side is the knowledge of what they need to do to stay safe: walk away, refuse the offer, or find a different path. For decades, doctors and therapists have tried to help people navigate this crossroads by teaching them strategies in quiet offices. They might role-play a refusal or discuss the dangers of a high-risk situation. But there is a gap between knowing what to do and actually doing it when the heart is racing, the room is loud, and the pressure is real. The mind can understand a rule in a calm room, but that rule often vanishes when the situation becomes chaotic and emotional.

This is where a new kind of technology is stepping in, not to replace the doctor, but to build a bridge between the office and the real world. Researchers are using virtual reality, a technology that surrounds a person with a computer-generated world, to recreate those high-pressure moments. Instead of just talking about a risky situation, a person can step inside a virtual bar, hear the clink of glasses, and face a virtual friend who insists they take a drink. The goal is to practice the act of saying no, or the act of leaving, while feeling the stress of the moment, but without the danger of real alcohol. A new review of research in this field, led by scientists at the University of Quebec at Chicoutimi, looks at how these digital tools are evolving. It asks a simple but profound question: are we just showing people the problem, or are we helping them practice the solution?

The review, which brings together studies from psychology, computer science, and addiction medicine, finds that the field is currently in a state of transition. For a long time, the primary use of virtual reality in treating alcohol use disorder was what the researchers call "cue exposure." In these setups, a person puts on a headset and looks at a virtual room filled with alcohol. They might see a bottle on a table or a fridge stocked with beer. The computer measures how much they want to drink when they see these things. This approach is useful because it allows doctors to see how a person reacts to triggers in a safe, controlled environment. It is like a stress test for the brain, showing exactly what makes a person crave a drink. However, the review points out a significant limitation in this method. In many of these studies, the person is a passive observer. They watch the virtual world, they feel the urge, but they do not have to do anything about it. They are not asked to pick up the bottle and put it back, or to turn and walk away from the virtual friend. They are just watching the danger, which is not the same as learning how to survive it.

The researchers argue that the next step for this technology is to move from passive watching to active doing. They describe a shift toward what they call "situated action." In this newer approach, the virtual world is not just a display; it is a place where the person has to make choices and act on them. Imagine a virtual scenario where a friend offers a drink. In the old way, the person would just see the offer and feel the craving. In the new way, the person must physically reach out to push the glass away, or turn their body to leave the table, or speak to the virtual character to say no. The computer tracks these movements and the choices the person makes. If they refuse the drink, the virtual world reacts; maybe the friend accepts the refusal, or maybe they push harder, and the person has to try again. This is not just about seeing the trigger; it is about rehearsing the response. The review suggests that this kind of active practice, where the body and the mind work together to solve a problem, is much closer to how people learn to cope in real life.

Another major theme in the paper is the role of social connection and empathy. Alcohol use disorder does not happen in a vacuum; it happens between people. Often, the hardest part of quitting is dealing with the social pressure of friends, family, or colleagues. The review explores how virtual reality can be used to practice these social interactions. It also looks at a more complex idea: can virtual reality help a person understand how their drinking affects others? Some researchers have tried to create experiences where a person sees the world through the eyes of a family member who is hurt by the drinking. The idea is that by stepping into someone else's shoes, the person might feel more empathy and understand the consequences of their actions more deeply. However, the authors are careful to note that this is still an experimental area. While virtual reality can make a person feel like they are "there" with another person, it does not automatically make them more empathetic or change their behavior in the long term. The technology can create a powerful moment of understanding, but turning that moment into a lasting change in how a person treats others is a much harder challenge that is not yet fully solved.

The paper also takes a hard look at the limits of what these technologies can do right now. The researchers emphasize that while virtual reality is excellent at creating realistic situations and measuring immediate reactions, we do not yet have strong proof that it changes a person's life over the long term. Many studies are small, and they often stop measuring results as soon as the person takes off the headset. We know that a person can feel less craving in the moment or say they feel more confident after a session, but we do not yet know if this means they will drink less or stay sober for months or years. The review warns against treating these tools as a magic cure. They are not a standalone treatment that can replace therapy or medication. Instead, they are best understood as powerful practice tools, like a flight simulator for a pilot. A simulator can teach a pilot how to handle an engine failure in a storm, but it does not replace the need for a real plane or a real flight instructor. Similarly, virtual reality can help a person practice saying no to a drink, but it works best when it is part of a broader treatment plan that includes human support and real-world guidance.

There are also practical hurdles to getting these tools into everyday use. The review highlights that not everyone finds these systems easy to use. Some people feel sick when they wear the headset, a common side effect known as cybersickness. Others might find the controls confusing or the scenarios too stressful. For the technology to be helpful, it needs to be comfortable and safe. The researchers suggest that future designs need to pay more attention to these details, ensuring that the experience is not just realistic, but also supportive. They also point out that the way these systems are built often lacks variety. Many virtual bars look the same, and the virtual friends often say the same things. Real life is messy and unpredictable, with different kinds of pressure and different kinds of people. If the practice is too simple, it might not prepare a person for the complexity of the real world.

Ultimately, this review paints a picture of a field that is full of promise but still finding its footing. The technology has proven it can create realistic environments and trigger the same feelings a person would have in a real bar or party. It has shown that people can learn to interact with these environments and practice coping strategies. But the big question remains: does this practice stick? Does the skill learned in the virtual world transfer to the real world when the stakes are high and the emotions are raw? The authors conclude that we are not there yet. The evidence is strong for the ability to create the experience, but the evidence for long-term change is still emerging. They call for more rigorous studies that follow people over time, looking at whether these digital rehearsals actually help them stay sober in their daily lives. Until then, these immersive systems should be seen as a valuable addition to the toolkit of addiction treatment, a way to bring the practice of recovery into a safe space, but not a replacement for the hard work of recovery itself. The path forward involves building better, more varied, and more empathetic virtual worlds, and then testing them carefully to see if they can truly help people cross the gap between knowing what to do and actually doing it.
