Abstract Several alternatives vie today for recognition as the most plausible ontology, from physicalism to panpsychism. By and large, these ontologies entail that physical structures circumscribe consciousness by bearing phenomenal properties within their physical boundaries. The ontology of idealism, on the other hand, entails that all physical structures are circumscribed by consciousness in...
3,4-Methylenedioxymethamphetamine (MDMA) is known to induce dependence and psychosis in humans. Brain-derived neurotrophic factor (BDNF) is involved in the synaptic plasticity and neurotrophy in midbrain dopaminergic neurons. This study aimed to investigate the role of BDNF in MDMA-induced dependence and psychosis. A single dose of MDMA (10mg/kg) induced BDNF mRNA expression in the prefrontal...
Toxicity of 3,4-methylenedioxymethamphetamine (MDMA) towards biogenic amine neurons is well documented and in primate brain predominantly affects serotonin (5-HT) neurons. MDMA induces damage of 5-HT axons and nerve fibres and intracytoplasmic inclusions. Whilst its pathobiology involves mitochondrially-mediated oxidative stress, we hypothesised MDMA possessed the capacity to activate...
OBJECTIVE: Literature is quite poor about the clinical effects of novel psychoactive substances (NPS) and the long-term consequences of NPS use in psychiatric patients. Consequently, it is of the greatest interest to examine which effects NPS can exert in patients with previous severe mental illness (SMI), such as psychotic patients. The aim of this work was a comprehensive review about NPS use...
The objective of this study is to explore the users' perspectives regarding the effects and toxicity of cathinones. A systematic search of Internet discussion forums yielded 303 threads relevant to the research objectives. The threads were analysed by conventional content analysis where concepts were developed from codes and themes. The study identified 3 main themes in relation to cathinone...
Until the mid-60s, only the Mazatecs, an indigenous group from Oaxaca, Mexico, used Salvia Divinorum (S. divinorum) due to its hallucinogen properties. Later it was found that the hallucinogen effects of this plant were caused by the presence of a neoclerodane diterpene Salvinorin A (salvinorin A), which is a highly selective agonist of kappa-opioid receptor (KOR) that cause more intense...
Purpose of ReviewThe lack of clarity about the effect of cannabis use on cognition may be attributable to the considerable heterogeneity among studies in terms of cannabis composition. This article selectively reviews studies examining the distinctive effects of cannabinoids on human cognition, particularly those of delta-9-tetrahydrocannabinol (Δ9-THC) and cannabidiol (CBD).Recent...

The study involved the group of patients (n = 40) with psychotic disorders who used synthetic cannabinoids (spice). Among the psychotic disorders according to ICD-10 we allocated intoxication delirium (F12.03; 35 %), schizophreniform disorder (F12.50; 60 %), disorder with predominantly manic psychotic symptoms (F12.55; 5 %). The average age of patients was 25.2 ± 4.4 years. Hereditary...
While addressing global problems including conflict and violence is a common human agenda, they are human-caused: They are created and sustained through our thoughts. Though external causes and conditions cannot be ignored, the most fundamental problem is an epistemological one—our way of knowing and viewing the world. As the shape of the global conditions relies on our thoughts or ways of...
Plant-based psychedelics, such as psilocybin, have an ancient history of medicinal use. After the first English language report on LSD in 1950, psychedelics enjoyed a short-lived relationship with psychology and psychiatry. Used most notably as aids to psychotherapy for the treatment of mood disorders and alcohol dependence, drugs such as LSD showed initial therapeutic promise before...
