“I noticed that people who have addictions and those who teach mindfulness speak the same language. Mindfulness teachers will tell you that stress is caused by craving. If you can let go of that craving, then your stress will dissolve, and practicing mindfulness is the way to do that.” – Judson Brewer
There are many addictions, from exercise, to alcohol, to sex, to drugs, to gambling, to cigarettes. There are a number of differences produced by the specific nature of each addiction. But, there are also some general features. The core components of addiction include an enhanced incentive for the activity or substance (craving), impaired self-control (impulsivity and compulsivity), emotional dysregulation (negative mood) and increased reactivity to stress.
Mindfulness training has been shown to be helpful with each of these components, decreasing cravings, impulsiveness, and psychological and physiological responses to stress, and increasing emotion regulation. It is no wonder then that mindfulness training has been found to be effective for the treatment of a variety of addictions. Addictions appear to act via changes to the brain systems affecting self-control; activity in the Anterior Cingulate Cortex (ACC) and adjacent medial Prefrontal Cortex (mPFC). Mindfulness training has also been shown to alter the activity of these structures in the opposite direction through a process called neuroplasticity. This makes a case that mindfulness acts to help in the treatment of addictions by altering the same structures involved in addictions.

Tang and colleagues review a number of their studies on the relationships between mindfulness, the psychological properties of addictions, and the neural systems underlying self-control and addiction. They employed a mindfulness meditation training technique called integrative body–mind training (IBMT) and found that it improved executive function, emotions, and responsiveness to stress.
In other studies, they investigated the brain’s response to IBMT and found that it increased activity in the Anterior Cingulate Cortex (ACC) which is known to be involved in emotion regulation and the activity of the parasympathetic nervous system, that is known to be an antidote to stress responses. These results strongly suggest that mindfulness training (IBMT) acts in ways that would tend to counteract the effects of addictions including self-control and stress responsiveness. Tang and colleagues went on to test IBMT on students who were addicted to cigarettes (nicotine). They found that smokers had lower activity in Anterior Cingulate Cortex (ACC) and the medial Prefrontal Cortex (mPFC). But, IBMT training significantly reduced cigarette smoking and increased both ACC and mPFC activity.
These results suggest that mindfulness meditation increases activity in ACC and mPFC which are involved in emotion regulation and self-control. The improvements in these areas, in turn, assist in the prevention and treatment of addictions. These studies have produced an integrated theory of how mindfulness effects addiction by altering the nervous system in such a way as to counteract the psychological issues that underlie addictions. These studies are leading to a better understanding of how mindfulness training produces improvements in addictions.
So, improve self-control and emotionality with mindfulness and reduce addictions.
“mindfulness is likely an effective tool in helping people with addiction because it’s a single, simple skill that a person can practice multiple times throughout their day, every day, regardless of the life challenges that arise. With so much opportunity for practice—rather than, say, only practicing when someone offers them a cigarette—people can learn that skill deeply.” – James Davis

Abstract
BACKGROUND: The core clinical symptoms of addiction include an enhanced incentive for drug taking (craving), impaired self-control (impulsivity and compulsivity), emotional dysregulation (negative mood) and increased stress reactivity. Symptoms related to impaired self-control involve reduced activity in anterior cingulate cortex (ACC), adjacent prefrontal cortex (mPFC) and other brain areas. Behavioral training such asmindfulness meditation can increase the function of control networks including those leading to improved emotion regulation and thus may be a promising approach for the treatment of addiction.
METHODS: In a series of randomized controlled trials (RCTs), we tested whether increased ACC/mPFC activity is related to better self-control abilities in executive functions, emotion regulation and stress response in healthy and addicted populations. After a brief mindfulness training (Integrative Body-Mind Training, IBMT), we used the Positive and Negative Affect Schedule (PANAS) and Profile of Mood States (POMS) to measure emotion regulation, salivary cortisol for the stress response and fMRI for brain functional and DTI structural changes. Relaxation training was used to serve as an active control.
RESULTS: In both smokers and nonsmokers, improved self-control abilities in emotion regulation and stress reduction were found after training and these changes were related to increased ACC/mPFC activity following training. Compared with nonsmokers, smokers showed reduced ACC/mPFC activity in the self-control network before training, and these deficits were ameliorated after training.
CONCLUSIONS: These results indicate that promoting emotion regulation and improving ACC/mPFC brain activity can help for addiction prevention and treatment.
