The largest neuroscience study to date of mindfulness as a treatment for addiction shows that Mindfulness-Oriented Recovery Enhancement (MORE) can decrease opioid misuse by changing the brain.
The study, published in the top journal Science Advances, provides new insight into the neurobiological mechanisms by which mindfulness treats addiction. Study findings provide a promising, safe and accessible treatment option for the more than 9 million Americans misusing opioids. Eric Garland is the lead author on the paper and is a distinguished professor, and associate dean for research at the University of Utah College of Social Work. He also directs the University of Utah’s Center on Mindfulness and Integrative Health Intervention Development.
Garland’s study builds on previous research measuring the positive effects of theta waves in the human brain. Researchers have found that individuals with low theta waves tend to experience a wandering mind, trouble concentrating or they ruminate on thoughts about themselves. Theta waves can best be viewed on electroencephalogram, or EEG scans of the frontal midline regions of their brains. Low theta waves result in a loss of self-control as the brain slips into its default mode of automatic habits. In contrast, when a person is focused, present and fully absorbed in a task, EEG scans will show increased frontal midline theta wave activity.
“With high theta activity, your mind becomes very quiet, you focus less on yourself and become so deeply absorbed in what you are doing that the boundary between yourself and the thing you are focusing on starts to fade away. You lose yourself in what you are doing,” said Garland.
Garland’s new study showed it is in this mindful, theta wave state that people begin to experience feelings of self-transcendence and bliss, and the brain changes in ways that actually reduce one’s addictive behaviors.
ABOUT THE STUDY
Garland’s research team recruited 165 adults with long-term opioid use for study. Participants were randomly placed into either the control group that participated in supportive group psychotherapy, or the experimental group taught to incorporate Mindfulness-Oriented Recovery Enhancement (MORE) into their daily lives. Before and after the eight weeks of study treatment, all participants were brought into the research lab and had their brain waves measured with EEG while they were asked to try to practice mindfulness meditation. Participants were assessed for opioid misuse for nine months after the treatment ended.
MORE is an eight-week, mindfulness-based therapy created by Garland to treat addiction, pain and emotional distress by promoting self-awareness and self-regulation of automatic and addictive habits. In a large clinical trial recently published in JAMA Internal Medicine, MORE was shown to reduce opioid misuse by 45%, more than doubling the effect of standard therapy.
Study participants in the MORE group learned to practice mindfulness meditation by focusing their attention on their breath or body sensations for sustained periods of time, and to refocus their attention when their minds began to wander into obsessive thinking about drugs or life stressors.
STUDY FINDINGS
Participants showed more than twice as much frontal midline theta brain activity following treatment with MORE, whereas those in supportive therapy showed no increase in theta. Participants in MORE who showed the biggest increases in theta waves reported more intense experiences of self-transcendence during meditation, including the sense of one’s ego fading away, a sense of oneness with the universe or feelings of blissful energy and love.
MORE also led to significant decreases in opioid misuse through the nine-month follow-up. These reductions in opioid misuse were caused in part by the increases in frontal midline theta brain waves. Garland explained that by achieving “tastes of self-transcendence” through meditation, the mindfulness therapy boosted theta waves in the frontal lobes of the brain to help participants gain self-control over their addictive behaviors.
“Mindfulness can create a pathway for us to transcend our limited sense of self,” said Garland. “Civilizations have known for thousands of years that self-transcendence, the experience of being connected to something greater than ourselves, has powerful therapeutic benefits.”
This, he explained, is a part of why some cultures engage in spiritual practices, practice deep meditation or use psychedelic substances like psilocybin mushrooms. Even in the popular 12-step addiction treatment program, the 11th step—seeking conscious contact with a higher power through prayer or meditation—taps into this same mechanism to promote recovery from addiction.
The state of transcendence can be like a blissful, natural high. Garland stated, “Rather than seeking a high from something outside of yourself like a drug, meditation can help you to find an even greater sense of pleasure, peace and fulfillment from within.”

This is one of the strongest effect sizes ever shown for a treatment for opioid misuse among people with chronic pain. MORE also reduced opioid use; 36% of patients treated with MORE were able to reduce their opioid dose in half or greater. At the same time, 50% of patients treated with MORE experienced clinically significant reductions in pain severity. And, although nearly 70% of patients met criteria for major depressive disorder (MDD) at the beginning of the trial, the mean depression symptom severity score for patients treated with MORE no longer surpassed the threshold for MDD by the end of the study. These therapeutic effects lasted for 9 months after the end of treatment, demonstrating the sustained efficacy of MORE. We followed patients for almost a year after they enrolled in the study, representing the longest follow-up ever conducted for the MORE intervention.
