This paper reimagines drug policy--specifically psychedelic drug policy--through the prism of human rights. Challenges to the incumbent prohibitionist paradigm that have been brought from this perspective to date--namely by calling for exemptions from criminalisation on therapeutic or religious grounds--are considered, before the assertion is made that there is a need to go beyond such reified ...

(This article discusses exploratory work that was interrupted early in 1966 when the Food and Drug Administration, as a strategy in combating the illicit-use problem, declared a moratorium on research with normal human subjects. In view of the preliminary nature of the work, it would not under ordinary circumstances have been submitted for publication. However, because of the significance of th...

Psychedelic psychotherapy was shown to be a potential benefit for alcoholism treatment in the "60s," but different methodologies made it difficult to generalize across studies. The requisite development of appropriate sophistication for these studies was not possible to do after they were scheduled in 1970 and their use was strictly limited. However, at about this time, ketamine was being shown...

Amphetamine, methylphenidate, morphine, heroin and ketamine are all drugs that can potentially be used clinically but, whenever we hear the word MDMA, the first thoughts that come to mind are of ecstasy, rave parties and people behaving in an odd manner and experiencing hallucinations, paranoia and disinhibition. Recently, there has been a lot of discussion on the use of MDMA for treatment-resi...

Psilocybin is a classic psychedelic and a candidate drug model of psychosis. This study measured the effects of psilocybin on resting-state network and thalamocortical functional connectivity (FC) using functional magnetic resonance imaging (fMRI). Fifteen healthy volunteers received intravenous infusions of psilocybin and placebo in 2 task-free resting-state scans. Primary analyses focused on ...

Lysergic acid diethylamide (LSD) is the prototypical psychedelic drug, but its effects on the human brain have never been studied before with modern neuroimaging. Here, three complementary neuroimaging techniques: arterial spin labeling (ASL), blood oxygen level-dependent (BOLD) measures, and magnetoencephalography (MEG), implemented during resting state conditions, revealed marked changes in b...

Psychedelic drugs produce profound changes in consciousness, but the underlying neurobiological mechanisms for this remain unclear. Spontaneous and induced oscillatory activity was recorded in healthy human participants with magnetoencephalography after intravenous infusion of psilocybin--prodrug of the nonselective serotonin 2A receptor agonist and classic psychedelic psilocin. Psilocybin redu...

Interest in the therapeutic potential of psychedelic substances has recently resumed. During an early phase of human psychedelic research, their therapeutic application in different pathologies had been suggested, and the first evidence for efficacy was provided. The range of recent clinical applications of psychedelics spans from cluster headaches and obsessive-compulsive disorder to addiction...

CNS deficiency of 5-hydroxytryptamine (serotonin) has been implicated as a biochemical basis in some forms of depression. Existing drug modalities for treating depression include some with serotonergic effects. Studies suggest that psychedelic drugs are also serotonergic. This may indicate a role for psychedelics in the treatment of depression. Such treatment has already been attempted using ps...
