The Effectiveness of Mindfulness in the Treatment of Methamphetamine Addiction Symptoms: Does Neuroplasticity Play a Role?

INTRODUCTION

Methamphetamine is a highly stimulating psychoactive drug that causes life-threatening addictions and affects millions of people around the world. Its effects on the brain are complex and include disturbances in the neurotransmitter systems and neurotoxicity. There are several known treatment methods, but their effectiveness is moderate. It must be emphasised that no drugs have been approved for treatment. For this reason, there is an urgent need to develop new, effective, and safe treatments for methamphetamine. One of the potential treatments is mindfulness meditation. In recent years, this technique has been researched extensively in the context of many neurological and psychiatric disorders.

METHODS

This review explores the use of mindfulness in the treatment of methamphetamine addiction. Searches were conducted in the PubMed/Medline, Research Gate, and Cochrane databases.

RESULTS

Ten studies were identified that used mindfulness-based interventions in the treatment of methamphetamine addiction. The results show that mindfulness is an effective form of reducing hunger, risk of relapses, stress indicators, depression, and aggression, alone or in combination with transcranial direct current stimulation (tDCS). Mindfulness also improved the cognitive function in addicts. The included studies used only behavioural measures. The potential mechanisms of mindfulness in addiction were explained, and it was proposed that it can induce neuroplasticity, alleviating the symptoms of addiction.

CONCLUSIONS

Evidence from the studies suggest that mindfulness may be an effective treatment option for methamphetamine addiction, used alone or in combination with tDCS. However, further high-quality research is required to establish the role of this treatment option in this field. The use of neuroimaging and neurophysiological measures is fundamental to understand the mechanisms of mindfulness.

Is mindfulness practice "at risk" of increasing spirituality? Systematic review and critical analysis of a claimed effect

INTRODUCTION

Mindfulness meditation has gained prominence in somatic and psychiatric care in several countries including France. Studies have shown its effectiveness in various conditions, in particular the prevention of depressive relapses. However, there are criticisms and concerns about its potential links to Buddhism and spirituality, raising issues of secularism and sectarianism. This issue is particularly conflicting in France with regard its historical and political relationship with secularism.

OBJECTIVES

This study aims to assess quantitative data regarding the impact of mindfulness meditation on spirituality and religiosity using quantitative validated scales.

METHODS

A systematic review was conducted. PubMed was searched for relevant studies using keywords related to mindfulness and spirituality/religiosity scales. Four scales assessing spirituality were identified: FACIT-sp, INSPIRIT, DSES, and DUREL. Qualitative analysis determined if scale items pertained to spirituality or other topics considered by opponents to mindfulness as "at risk" for deviances or sectarian aberrations. Quantitative analysis assessed the effect size of changes in scale scores before and after mindfulness meditation interventions.

RESULTS

Eighteen studies were analyzed, with varying scales and program durations including 1272 participants. Qualitative analysis showed that most scales contained items related to spirituality as well as "at risk" elements like religion and mysticism. Quantitative analysis revealed that a few studies reported significant increases in spirituality scores following mindfulness meditation, but the clinical relevance of these changes was questioned. In general, control groups had smaller score changes.

INTERPRETATION

While some studies suggest a potential increase in spirituality due to mindfulness meditation, the clinical significance of these findings remains uncertain. Moreover, mindfulness meditation's ties to Buddhism are disputed, and its roots are intertwined with various psychotherapy traditions that incorporate spirituality. The role of secularism in psychotherapy is also debated in France, emphasizing the need for proper use and regulation policy rather than prohibition of mindfulness-based approaches. This study highlights the complexity of assessing the impact of mindfulness meditation on spirituality and religiosity. It suggests that a pragmatic approach focusing on risk and harm reduction may be more suitable than labeling the practice as "at risk". Further research is needed to clarify these issues in the specific cultural context of France.

How Chanting Relates to Cognitive Function, Altered States and Quality of Life

Chanting is practiced in many religious and secular traditions and involves rhythmic vocalization or mental repetition of a sound or phrase. This study examined how chanting relates to cognitive function, altered states, and quality of life across a wide range of traditions. A global survey was used to assess experiences during chanting including flow states, mystical experiences, mindfulness, and mind wandering. Further, attributes of chanting were assessed to determine their association with altered states and cognitive benefits, and whether psychological correlates of chanting are associated with quality of life. Responses were analyzed from 456 English speaking participants who regularly chant across 32 countries and various chanting traditions. Results revealed that different aspects of chanting were associated with distinctive experiential outcomes. Stronger intentionality (devotion, intention, sound) and higher chanting engagement (experience, practice duration, regularity) were associated with altered states and cognitive benefits. Participants whose main practice was call and response chanting reported higher scores of mystical experiences. Participants whose main practice was repetitive prayer reported lower mind wandering. Lastly, intentionality and engagement were associated with quality of life indirectly through altered states and cognitive benefits. This research sheds new light on the phenomenology and psychological consequences of chanting across a range of practices and traditions.

How Does Buddhist Contemplative Space Facilitate the Practice of Mindfulness?

This paper examines the spaces where Buddhist spiritual activity—specifically mindfulness practice—takes place, exploring how contemporary urban Buddhist contemplative places may benefit people’s mindful experience. Historical Buddhist contemplative places are examined through a literature review of Buddhist philosophy and Buddhist architecture and landscape. A case study of Kagyu Samye Dzong London, UK (KSDL) in the contemporary western context is then presented, drawing upon mixed methods (qualitative spatial analysis, questionnaires with mindfulness practitioners, and an in-depth interview with the director of the Buddhist center). This study investigates the relationship between the Buddhist spiritual activity of mindfulness practice and one specific physical space, exploring how the KSDL has been designed and is used to facilitate such mindfulness awareness and insight. Results suggest that quiet, solitude, and the presence of nature are three tangible spatial qualities that can facilitate mindful practice to some extent. However, additional relational or intangible qualities, namely the presence of The Three Jewels and blessings, are equally if not more important when sustaining mindfulness for Buddhist practitioners, and these contemplative qualities are more than “spatial”. Both the physical tangible qualities and intangible qualities are indispensable in the contemplative space and in influencing one’s practice. Findings evidence the importance of physical design and space for supporting contemporary mindfulness practitioners, whilst acknowledging that mindfulness emanates from—and can ultimately be discovered from—within.

Promoting Spiritual Healing by Stress Reduction Through Meditation for Employees at a Veterans Hospital: A CDC Framework-Based Program Evaluation

Background: Employees in the Veterans Affairs (VA) hospital experience psychological stress from caring for vulnerable veteran populations. Evidence suggests that mindfulness meditation decreases stress in health care employees and military personnel. The purpose of this worksite program was to explore the acceptability of a mindfulness meditation program among VA workers. Methods: Chaplain residents developed the "Promoting Spiritual Healing by Stress Reduction Through Meditation" (Spiritual Meditation) program for employees in a VA hospital. To evaluate acceptability, a 13-multiple-choice-item survey with an open-ended question was administered after the intervention. Descriptive statistics and qualitative content analysis were performed. Findings: In 29 participants, 70% to 100% agreed with positive statements for the personal learning experience, program components, teacher quality, time to practice, and place to practice. Two categories emerged from qualitative responses: "positive practical experience of Spiritual Meditation" and "perceived values from Spiritual Meditation." Conclusion/Application to Practice: Occupational health nurses are uniquely positioned to lead and collaborate with chaplains to deliver Spiritual Meditation in their workplace setting.
