Combining meditation with psychoactive substances is often assumed to be a niche practice centred on classic psychedelics. We sought to broaden this narrative in two cross-sectional studies. Study 1 used a broad naturalistic sample (N = 1,391) to examine the prevalence of substance use, meditation, and their simultaneous combination, as well as associations with subjective happiness. Study 2...
Psychedelic substances and meditation can elicit personally meaningful experiences that support well-being, yet their relative and combined contributions remain unclear. Meditation typically produces gradual improvements through sustained practice, whereas psychedelics may induce acute shifts. To examine these dynamics, we re-analysed data from two cross-sectional online surveys using multiple...
Both psychedelic substances and meditation have been proposed to facilitate personally meaningful and transformative experiences, with insights playing a central role. However, previous research has mainly relied on questionnaires, limiting the range of insights that can be identified. In this study, we recruited participants who provided narrative reports of insights in personally meaningful...
Increased psychological flexibility (PF) may underlie the lasting positive effects of psychedelic experiences on mental well-being. The associations between different components of PF, psychological inflexibility (PI), and well-being with psychedelic use are not well understood. We conducted a cross-sectional internet survey of participants (N = 629) with experience of classical psychedelics....
It has been proposed that psychedelics promote wellbeing through spiritual-type transformations, involving changes in metaphysical beliefs. Past empirical research shows a link between the use of psychedelics and the endorsement of non-physicalist metaphysical beliefs. However, non-physicalist beliefs encompass a wide range of metaphysical ideas, and their links to wellbeing and psychedelics...
In search for the neural correlates of consciousness (NCCs), it is important to isolate the true NCCs from their prerequisites, consequences, and co-occurring processes. To date, little is known about how attention affects the event-related potential (ERP) correlates of auditory awareness and there is contradictory evidence on whether one of them, the late positivity (LP), is affected by...
Medical cannabis (MC) is increasingly used for chronic pain, but it is unclear how it aids in pain management. Previous literature suggests that MC could holistically alter the pain experience instead of only targeting pain intensity. However, this hypothesis has not been previously systematically tested. A retrospective internet survey was used in a sample of Finnish chronic pain patients (40...
