N-Benzyl-derived phenethylamines are highly active (psychedelic) 5-HT2AR (serotonin 2A receptor) agonists used as biochemical tools and on the drug market. The impact of adding an N-benzyl substituent to the tryptamine core structure has scarcely been studied. A recent systematic exploration of N-benzyl-substituted (5-MeO-)tryptamines revealed a surprisingly low activity in a Ca2+ mobilization...
Psilocybin, N,N-dimethyltryptamine (DMT), lysergic acid diethylamide (LSD), and 3,4-methylenedioxymethamphetamine (MDMA) are psychedelic compounds with therapeutic potential for depression, anxiety, and post-traumatic stress. However, their relevance to endurance athletes, who face particular psychological and physical stressors, remains underexplored. This study combines a conceptual overview...
Psychedelic drugs produce effects on the mind that manifest as an apparent expansion of consciousness often accompanied by hallucinations. Psychedelics, which act as agonists at serotonin 5-HT2A receptors in the brain, include psilocybin, 5-methoxydimethyltryptamine, and N,N-dimethyltryptamine (tryptamine derivatives), mescaline (a phenethylamine derivative), and lysergic acid diethylamide...
IntroductionThe use of psychedelics has increased in Canada in recent years. Although non-medical psilocybin use is prohibited under the Controlled Drugs and Substances Act, we previously documented the emergence of grey-market brick-and-mortar psilocybin retailers. This study examined changes in the number, composition, and geographic distribution of Canadian psilocybin retail stores between...

Clinical trials of psychedelics have shown preliminary promise for the treatment of psychiatric conditions such as major depressive disorder, substance use disorder, and treatment resistant depression.The most common psychedelic administration routes explored so far include intravenous injection, heated vapor inhalation, or a simple buffered salt solution administered to the nasal cavity.Given...
Bufotenin (also spelt as bufotenine) and its methylated derivative, 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT), are potent psychedelics that are found in many plants but also excreted by some species of toads. The compounds are regulated differently around the world, and although used in traditional medicine, 20th-century prohibition culture has slowed research into their utility for...
S elective S erotonin R euptake I nhibitors (SSRIs) and two psychedelics, Psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine), and MDMA (3,4-Methylenedioxymethamphetamine) act on serotonergic-related neural circuits and function as serotonin modulators. All three molecules are either currently used or proposed as novel therapeutic modalities to treat P ost- T raumatic S tress D isorder (PTSD)....
Summarizes preclinical and clinical evidence on ayahuasca—a traditional Amazonian brew combining N, N-Dimethyltryptamine (DMT) and β-carbolines—in treating depression, anxiety, post-traumatic stress disorder, substance use, eating, and personality disorders. Preclinical work shows enhanced neuroplasticity, reduced inflammation, and oxidative stress. Human neuroimaging reveals decreased default...
