Since its emergence in the 1960s, the serotonergic theory of depression bore fruit in the discovery of a plethora of antidepressant drugs affecting the lives of millions of patients. While crucial in the history of drug development, recent studies undermine the effectiveness of currently used antidepressant drugs in comparison to placebo, emphasizing the long time it takes to initiate the...
Aboriginals of Latin America have used DMT (N,N-dimethyltryptamine) in ritualistic ceremonies for centuries. Nevertheless, there are limited data on web users' interest concerning DMT. We aim to review the literature and explore the spatial-temporal mapping of online search behavior concerning DMT, 5-MeO-DMT, and the Colorado River toad via Google Trends over the past 10 years (2012-2022) while...
Much research has focused on the modeling of the near-death experience (NDE) by classical and atypical psychedelics; however, to date, no study has reported on the relationship between the NDE and the experience induced by the highly potent, endogenous psychedelic drug 5-Methoxy-DMT (5MeO-DMT). This article presents a case study of an individual who is popularly documented to have had a...
N,N-Diallyltryptamine (DALT) and 5-methoxy-N,N-diallyltryptamine (5-MeO-DALT) are two tryptamines synthesized and tested by Alexander Shulgin. In self-experiments, 5-MeO-DALT was reported to be psychoactive in the 12-20mg range, while the unsubstituted compound DALT had few discernible effects in the 42-80 mg range. Recently, 5-MeO-DALT has been used in nonmedical settings for its psychoactive...
N,N-dimethyltryptamine (DMT) is classified as a naturally occurring serotonergic hallucinogen of plant origin. It has also been found in animal tissues and regarded as an endogenous trace amine transmitter. The vast majority of research on DMT has targeted its psychotropic/psychedelic properties with less focus on its effects beyond the nervous system. The recent discovery that DMT is an...
A 24-year-old male died suddenly following the intravenous injection of what was believed to be the ring-derivate amphetamine 'ecstasy' (MDMA). Toxicological analyses of the victim's blood and the injected material, however, failed to reveal MDMA, but showed instead low levels of bufotenine, a tryptamine derivative alkaloid found in the secretions of various toads. In addition, resibufogenin,...
In a previous study it was observed that fluoxetine potentiates the stimulus effects of lysergic acid diethylamide (LSD). In the present investigation, stimulus control was established in groups of rats using as training drugs the hallucinogens lysergic acid diethylamide (LSD); 0.1 mg/kg), (-)-2,5-dimethoxy-4-methylamphetamine [(-)-DOM; 0.56 mg/kg], ibogaine (10 mg/kg), and...
AbstractAnthropologists have long speculated that ancient peoples of Mesoamerica used a toad,Bufo marinus, as a ritual intoxicant. This hypothesis rests on many iconographic and mythological representations of toads and on a number of speculative ethnographic reports. We rejectB. marinusas a candidate for such use because of the toxicity of its venom. A more likely candidate is the Sonoran...
Psychedelics represent a potential breakthrough for treatment-resistant depression; however, the prolonged in-clinic monitoring required for compounds such as psilocybin and lysergic acid diethylamide is a logistical hurdle to widespread use. Intranasal mebufotenin (5-methoxy-N,N-dimethyltryptamine), a 5-hydroxytryptamine 1A (5-HT1A) and 5-HT2A agonist associated with brief psychedelic...
Endogenous N,N-dimethyltryptamine (DMT) has been detected in mammals, but its physiological functions and the distribution of functionally relevant synthesis remain unresolved. This paper proposes prostatic tissue as a candidate peripheral site of synthesis. Oncology studies document indolethylamine N-methyltransferase (INMT) expression in human prostate samples, including adjacent...
