Entactogens such as 3,4-Methylenedioxymethamphetamine (MDMA, "molly", "ecstasy") appear to have unusual, potentially therapeutic, emotional effects. Understanding their mechanisms can benefit from clinical experiments with related drugs. Yet the first known drug with such properties, 3,4-Methylenedioxyamphetamine (MDA), remains poorly studied and its pharmacokinetics in humans are unknown. We...

Abstract The drug 3,4-methylenedioxymethamphetamine (MDMA, “ecstasy”, “molly”) is a widely used illicit drug and experimental adjunct to psychotherapy. MDMA has unusual, poorly understood socioemotional effects, including feelings of interpersonal closeness and sociability. To better understand these effects, we conducted a within-subjects double-blind placebo controlled study of the effects of...

Several laboratories have conducted placebo-controlled drug challenge studies with 3,4-methylenedioxymethamphetamine (MDMA), providing a unique source of data to examine the reliability of the acute effects of the drug across subject samples and settings. We examined the subjective and physiological responses to the drug across three different laboratories and investigated the influence of...

Salvinorin A (SA) is a highly selective kappa opioid receptor agonist and the putative psychoactive compound in Salvia divinorum (SD), an increasingly abused hallucinogenic plant. The objectives of this study were to characterize the physiological and subjective effects of SA versus placebo and measure drug and metabolite levels. Sublingual SA doses up to 4 mg were administered in dimethyl...

BACKGROUND: The mechanisms of drug-induced visions are poorly understood. Very few serotonergic hallucinogens have been studied in humans in decades, despite widespread use of these drugs and potential relevance of their mechanisms to hallucinations occurring in psychiatric and neurological disorders. METHODOLOGY/PRINCIPAL FINDINGS: We investigated the mechanisms of hallucinogen-induced visions...

There is growing use of Salvia divinorum (SD), a psychoactive plant that produces hallucinogen-like effects through a kappa opioid receptor (KOR) mechanism. Little is known about KOR agonist effects in humans and about users of SD. To characterize the reasons, methods, and reported consequences of SD use. Individuals reading SD-related pages of a drug-information website were invited to...
