This study evaluated the psychometric properties of the Spiritual Well-Being Scale (SWBS) in a Brazilian sample. We analyzed spiritual well-being, defined as existential well-being (EWB) and religious well-being (RWB), among individuals with varying religious and spiritual experiences, both users and non-users of psychedelics. The online cross-sectional survey was conducted in Brazil, from April to June 2022. The psychometric analyses demonstrated reliability and validity based on the internal structure and the relationship with satisfactory external variables concerning the RWB and EWB factors of the SWBS. Validity evidence was shown for both factors (RWB, EWB) with adequate reliability ratings. However, the RWB factor, which was entirely replicated, demonstrated the best group differentiation and internal consistency. Although both factors showed validity, the RWB factor exhibited superior psychometric indices for validity, group discrimination, and reliability. Regarding psychedelics, the association with RWB and EWB demonstrates a U-shaped pattern, as participants who never use these substances typically exhibit higher RWB and EWB indices, succeeded by frequent users. This finding underscores the need for additional studies to further explore the intricate interplay between psychedelics and spiritual well-being.

"Microdosing," defined as the consumption of small, sub-hallucinogenic quantities of psychedelic drugs, has gained recent popularity. Microdosing is a relatively new concept, therefore no scientific recommendations exist on how to prepare and consume microdoses. Many consumers obtain microdosing information online. Few studies have investigated the content of this information; thus, the present study aimed to do so by collecting a large set of online microdosing information. A qualitative approach was taken to compile and characterize online microdosing information. Medical databases, video websites, online forums, drug-specific websites and forums, search engines, and social media websites were searched. A total of 174 unique resources were found, detailing the types of substances, preparation methods, doses, schedules, and safety strategies used by people who microdose. Future research is recommended to further explore how people prepare microdoses through in-person interviews and sample collection.

Health-promoting lifestyle and behaviors play a crucial role in the prognosis of an illness as well as in healing. With the significant global burden of unhealthy lifestyle choices, their impact on individuals with substance use disorders can be particularly burdensome, hampering overall well-being. This study assesses health-promoting lifestyle and behavior and dietary habits among treatment-seeking male patients with opioid use disorders. This cross-sectional observational study enrolled 179 male patients undergoing treatment for opioid use disorder in a treatment center dedicated to addiction services. Data were collected using a semi-structured questionnaire, the Health-Promoting Lifestyle Profile II (HPLP-II), the Maudsley Addiction Profile, and a food frequency questionnaire adapted for the north Indian diet. The mean age of the sample was 31.5 years, and almost half of the participants were underweight (n = 86, 48.0%). Participants often engaged in some health-promoting behaviors, such as nutrition, stress management, spiritual growth, and interpersonal relations; and generally neglected aspects of physical activity and health responsibility. Over half of the participants consumed less energy than recommended, while about a fourth failed to meet daily protein intake recommendations. The study underscores the need to incorporate lifestyle and dietary assessment and modification alongside psycho-pharmacological treatment for patients with opioid use disorders.

There is a need for treatments that can reduce cravings in methamphetamine use disorder (MUD), which is trending upwards worldwide. The aim of this study was to evaluate the effect of modafinil treatment on substance craving in patients with MUD. The study included 100 patients with MUD who were being treated in an inpatient detoxification center. Patients were divided into two groups as modafinil group (MG) (n = 51) and non-modafinil group (NMG) (n = 49) and compared with each other in terms of sociodemographic data, severity of addiction, change in craving scores on the 1st, 7th and 14th days. The change in craving scores during the first week was found to be significantly greater in the modafinil group (MG) compared to the non-modafinil group (NMG) (p < .001), indicating that modafinil effectively reduced methamphetamine cravings within the first week of treatment. When the changes in craving levels were compared between the groups in the first and second week, the difference between the groups was not statistically significant (p > .05). The mean substance craving scores at hospitalization were higher in MG than NMG (p < .001). Modafinil may be beneficial in the treatment of MUD, especially when used in the first weeks of treatment, especially in patients with higher cravings at baseline.

Although several studies have well described the characteristics of people who use psychedelics alongside their motivations and beliefs, little research has examined the preferences surrounding the source of psychedelic substances. In an anonymous online survey, we collected data from 6,379 consumers of 11 different psychedelic substances from 85 different countries, exploring their preferences and perceptions on natural and synthetic psychedelics. There was a strong preference of natural sources over synthetic alternatives for psilocybin (75%), DMT (56%), and mescaline (56%). Moreover, 50.8% of respondents believed that the source impacts the psychedelic's psychological and physiological effects, while 34.4% of respondents had a neutral stance on the topic. Despite the preference for natural sources, 67.7% of respondents agreed to switch to using synthetic alternatives to psychedelic substances if it would lessen the environmental impacts caused by the overharvesting of natural sources. This study presents novel insights into consumer preferences on the source of popular psychedelic substances. This international survey is limited to respondents primarily belonging to anglophone regions of the world.

Mental health promotion and substance use prevention are essential issues at universities worldwide. Although research has identified risk and protective factors for substance use generally among college students, there is a paucity of knowledge about anxiolytic use. Thus, the main objective of this study was to analyze if prescription and non-prescription anxiolytic use was related to self-control, self-esteem and self-efficacy. A cross-sectional study design included 1,687 undergraduate students (M_age = 20.30 years; SD = 2.76) at a Spanish university. Validated instruments were administrated for data collection, under the supervision of a research team member. Descriptive analyses showed that almost 12% of the sample reports prescription anxiolytic use and more than 6% of non-prescription anxiolytic use in the last 6 months. There were considerable differences between genders, with females reporting higher consumption. Linear regression analyses showed that low self-control and low self-esteem predicted both prescription and non-prescription anxiolytic use. Being female predicted only non-prescription anxiolytic use. Considering these findings, strategies to improve self-control and self-efficacy among university students could be a successful element preventing or decreasing anxiolytic use and misuse.

Emerging evidence indicates that ayahuasca consumption may have beneficial mental health effects. This study undertakes the largest analysis to date of associations between naturalistic ayahuasca use and current mental health status via an online cross-sectional survey. The sample included 7,576 participants (average age 41, 47% female) who had consumed ayahuasca in religious, traditional, or non-traditional settings in over 50 countries. Bivariate analysis, multivariate linear regressions and generalized structural equation modeling were used to explore associations between ayahuasca use variables, current mental health (K10, SF-12 MCS), and psychological well-being change (PWG). The number of ayahuasca uses was found to be positively associated with current mental health status (all measures), and this remained highly significant in multivariate models, with little evidence of associations diminishing over time. Variables such as the strength of the mystical experience, self-insights, and community/social variables were also positively associated with current mental health and PWG, while acute extreme fear and integration difficulties were negatively associated. Findings suggest that naturalistic ayahuasca use is associated with better current mental health status and enhanced psychological wellbeing for individuals with and without a history of mental illness, independent of community effects, with certain variables contributing positively or negatively to these effects.

Evidence suggests that individuals who use methamphetamine are at a significantly higher risk of developing psychosis compared to non-users. This study aims to examine the rate of psychosis among methamphetamine users and to investigate factors related to methamphetamine-associated psychosis (MAP). Two thousand ninety-eight (2,098) individuals with methamphetamine use were admitted to outpatient care. Available admissions data included clinical interviews, the Addiction Profile Index (API), and API-clinical forms. MAP was identified in 267 (12.7%) participants. Our data analysis found significant sociodemographic, clinical, and personality differences between MAP and non-MAP cohorts on admission. Multivariate regression analysis revealed that older age (OR = 1.049), younger age of substance use onset (OR = 0.960), more frequent MA use (OR = 1.622), being single (OR = 1.974), lower education (OR = 0.46), increased number of withdrawal symptoms (OR = 1.100), higher lack of anger control scores (OR = 1.422), higher lack of assertiveness scores (OR = 1.396), and higher anxiety scores (OR = 1.715) were significantly associated with MAP. Although factors identified in this study represent state (on admission) rather than stable characterological traits, these results may nonetheless help us better characterize contextual factors associated with MAP in an outpatient population.

The use of ketamine and ketamine-assisted psychotherapy (KAP) for treatment of depression has grown dramatically, though much of these data are short term. The clinical profile of maintenance treatment remains poorly characterized. We assessed maintenance KAP for efficacy, tolerability, and reasons for dropout. This observational study retrospectively analyzed electronic health records from an addiction psychiatry practice offering intramuscular ketamine with contemporaneous psychotherapy for the treatment of depression. All patients receiving treatment between January 2016 and September 2022 were included, yielding 1,114 sessions from 70 patients. The response was quantified via the clinical global impression-severity scale. Side effects and reasons for dropout were extracted from charts. Comorbidities include an anxiety disorder (79%) or substance use disorder (49%). The induction yielded 82% response, maintained above 80% after six months (sessions q21 days, 1.13 mg/kg mean dose). Many (38%) remained in treatment for at least one year. Nausea management accounted for nearly all as-needed medication use. Antihypertensives were seldom utilized. Chronic side effects were notable for one case of ketamine use disorder, resulting in residential treatment. Dropouts cited logistical reasons half the time and side effects only 9.7% of the time. KAP yielded robust improvements in mood, anxiety, and substance use. Maintenance sessions effectively extended benefit and were largely well tolerated.

Presently, 24 states have legalized adult use (recreational) cannabis, each following medical-only access. Although states that pass adult use laws report substantial declines in the number of registered medical patients, these laws expand the market, potentially enhancing patient benefits. However, research on federal adult use cannabis legislation in Canada suggests that adult use laws negatively impact medical patients. The purpose of this mixed-methods study was to examine medical cannabis patients' perceptions of the impact of adult use cannabis laws in the US. We conducted an online survey with forced choice and open-ended questions in a convenience sample of 505 medical cannabis patients. Quantitative analysis indicated that adult use laws decreased stress and legal concerns, and that patient perceptions of cannabis product quality and availability were higher, but prices were also higher. Qualitative analysis largely aligned with quantitative findings, however data were somewhat divergent on price and product availability (with some patients reporting lower prices and accessibility issues). Mixed-methods analysis revealed that legalization also reduced patients' experience of social stigma. Addressing the patient concerns revealed by these data may help to restore or maintain patient access to affordable, medically relevant cannabis products as additional states merge medical cannabis programs into adult use paradigms.
