The hallucinogenic world of tryptamines: an updated review.

Archives of toxicology August 1, 2015 Ana Margarida Araújo, Félix Carvalho, Maria de Lourdes Bastos et al. 290 citations

Tryptamines are a broad class of hallucinogens that act primarily as agonists of the 5-HT2A receptor, producing profound changes in sensory perception, mood, and thought. Historically, natural tryptamines like psilocybin and DMT have been used in ritual contexts, but synthetic tryptamines such as AMT, 5-MeO-DMT, and 5-MeO-DIPT have recently emerged as recreational drugs, often sold as 'research chemicals' online. Reports of intoxication and deaths have raised international concern, though the lack of pharmacological and toxicological data hampers assessment of their public health harm. This review covers historical background, prevalence, patterns of use, legal status, chemistry, toxicokinetics, toxicodynamics, and physiological and toxicological effects in animals and humans.

Analytical investigation of legal high products containing Salvia divinorum traded in smartshops and internet.

Forensic science international September 1, 2014 Fernando Xavier Moreira, Félix Carvalho, Maria De Lourdes Bastos et al. 13 citations

Products containing the hallucinogenic plant Salvia divinorum, sold legally in smartshops and online, often mislead consumers about their potency and composition. Analysis of 10 such products, labeled with potencies from 5x to 60x, found that salvinorin A was the primary hallucinogen, along with three related compounds. Labeled concentrations of salvinorin A frequently did not match the actual amounts, and the true concentrations far exceeded the level needed to produce hallucinogenic effects. Safety information was often omitted, encouraging recreational use without adequate warnings.
