All previous studies of the sub-acute effects of ecstasy have failed to adequately control for group differences in psychopathology and past and concurrent substance use. The present study was designed to avoid these limitations. At an initial pre-drug baseline, a sample of 38 regular ecstasy users provided full substance histories and completed measures of personality and self-reported...

The current study examined the long-term effect of brief exposure to 3,4-methylenedioxymethamphetamine (MDMA) on local cerebral glucose utilization (LCGU) in specific brain regions immediately following administration of the 5-HT2A/2C receptor agonist, 1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI). Wistar rats (post-natal day (PND) 28, n = 24) were administered MDMA (5 mg/kg, i.p.) or...

2C-T-7 ('Blue Mystic'), an illicit compound which shows similarities with MDMA and other designer drugs, has been only occasionally identified in the EU, but discussion on the Internet between experimenters has recently grown significantly. We aimed at collecting together in a review the available information on 2C-T-7, both at the cyber and at the street market level. 2C-T-7 was first...

National drugs information strategies convey the message that use of Ecstasy is associated with an increase in both the incidence and severity of major depressive disorder. However, very little primary research supports this. Unlike apparent deficits in higher cognitive functions, most published studies have found no difference in self-reported depressive symptomatology between Ecstasy users...

The glutamate/N-methyl-D-aspartate receptor antagonist phencyclidine (PCP) has been shown to induce both positive and negative symptoms of schizophrenia, as well as cognitive deficits, thus providing a relatively valid model of psychosis. Isolation rearing from weaning in the rat has been proposed as a non-pharmacological model of psychosis. The aim of the present study was to explore the...

A case of hypnopompic hallucinations associated with donepezil is described. Electroencephalogram (EEG) and sleep EEG changes are common in Alzheimers Disease and acetylcholinesterase inhibitor drugs can affect rapid eye movement sleep and alertness. The importance of assessing sleep in patients treated with these drugs is discussed.

The cognitive and subjective effects of sub-anaesthetic doses of ketamine on healthy volunteers were examined. Twelve healthy volunteers received 25 mg ketamine, 10 mg ketamine and saline placebo, i.m. in a double-blind, Latin square design. A cognitive, perceptual and self-report test battery was administered over 45 min. The order of tests was rotated to control for timing effects. Ketamine...

Since the mid-1950s the pharmaceutical industry has developed a number of chemicals, including phencyclidine, ketamine and related arylcyclohexylamines (PCE and TCP), dizocilpine (MK-801), N-allylnormetazocine [ NANM, (±)SKF-10,047], etoxadrol, dioxadrol and its enantiomers dexoxadrol and levoxadrol, which produce a constellation of unusual behavioral effects in animals and man. The compounds...

In this article parallels are drawn between sleep and anaesthesia. Both can be described as 'behavioural states' in which stimulation and inhibition of certain neuronal groups will give rise to specific psychological states. The neuronal mechanisms leading to these states are reviewed and compared. Sensory information flow through the thalamus is reduced in sleep and anaesthesia, the thalamic...
