The objective of this study was to describe patterns of drug use in a sample of...

Harmine, a major alkaloid in ayahuasca (hoasca), is a selective and reversible inhibitor of the enzyme monoamine oxidase-A (MAO-A). It is also a selective inhibitor of the human cytochrome P450 isozyme 2D6 (CYP 2D6), which metabolizes harmine to a more hydrophilic derivative for eventual excretion. CYP 2D6 exhibits a wide range of polymorphisms in human populations, and variations in this...

Twenty nine decoctions of Banisteriopsis caapi from four different sources and one specimen of B. caapi paste were analyzed for N,N-dimethyltryptamine (DMT), tetrahydroharmine (THH), harmaline and harmine. Other plants were also used in the preparation of these products, typically Psychotria viridis, which provides DMT. There were considerable variations in alkaloid profiles, both within and...

The use of psychedelic substances within a context that emphasizes religious experiences and aims to provide spiritual insights is not a new phenomenon. However, the proscription of these substances in most modern societies leads to such use now typically occurring in an underground and idiosyncratic manner that often leaves individuals on their own with regard to the interpretation and...

An early theoretical analysis supposed changes in hemispheric integration as the basis of altered state of consciousness induced by psychoactive drugs. Brain imaging studies revealed right cortical activation after administration of hallucinogens. Recent studies on binocular rivalry suggest that interhemispheric switching is the neural substrate of the perceptual oscillations observed during...

Salvinorin A is a unique hallucinogen that is seeing increased use in humans. It is not currently a controlled substance and is used as a legal alternative to controlled substances. Usually smoked or buccally absorbed by chewing, doses of approximately 200 mcg can produce profound hallucinogenic effects of short duration. The mechanism of action of salvinorin A is at the kappa-opioid receptor....

This article aims to explore, through established scientific research and documented accounts of personal experience, the similarities between religious mystical experiences and some effects of D-lysergic diethylamide or LSD. LSD predominantly works upon the serotonergic (serotonin-using neurons) diffuse neuromodulatory system, which projects its axons to virtually all areas of the brain...

Historically, states of intoxication--like dreams and madness--are seen in either one of two opposed ways. The intoxicated are either "possessed" or "under the influence" of an external agency, or revealing hidden feelings or truths (in vino veritas). Along the same lines, artists who worked during LSD, mescalin or psilocybin intoxication often refer to feelings of either being "possessed" or...
