Background:Both the ICD-10 and the DSM-IV operate with a diagnosis of cannabis-induced psychotic disorder. Despite this, the diagnosis is controversial.A number of studies have shown that cannabis can induce short-lived psychotic symptoms, and that this could depend on factors such as genetic predisposition. To qualify for a diagnosis of ‘cannabis-induced psychosis’, however, the symptoms must...

Cannabis contains a myriad of different chemicals, more than 60 of which are unique to the plant and called cannabinoids. The main psychoactive ingredient is delta9-tetrahydrocannabinol (THC) and this produces the effects that users seek (Curran et al., 2002 Psychopharmacology 164: 61-70). When given intravenously to healthy humans, THC produces psychotic-like and anxiogenic effects (D’Souza et...

Epidemiological studies have reported that the increased risk of developing psychosis in cannabis users is dose related. In addition, experimental research has shown that the active constituent of cannabis responsible for its psychotogenic effect is Delta-9-Tetrahydrocannabinol (THC) (Murray et al, 2007). Recent evidence has suggested an increased in potency (% TCH) in the cannabis seized in...

Abstract Ketamine is an N-methyl-D-aspartate (NMDA) antagonist that has become increasingly recognized and utilized in the treatment of post-operative pain as a way to reduce opioid use. Overall ketamine is generally well tolerated, however it is associated with transient hypertension and neurologic "emergence phenomena" manifesting as dream-like states, irrational behavior, and delirium. From...

Abstract The recurrence of flashbacks without acute or chronic hallucinogen consumption has been recognized in the DSM IV criteria as the hallucinogen persisting perception disorder (HPPD). Perceptual disturbances may last for 5 years or more and represent a real psychosocial distress. We reported here a case of a 18-year-old young man presenting HPPD after a mixed intoxication with psylocibin...

AbstractPurposeTo test the hypothesis that recent onset psychotic patients who use cannabis will have psychotic symptoms that are more severe and more persistent than those who do not use cannabis.Subjects and methodsWe carried out a 4-year follow-up study of a cohort of 119 patients with recent onset of psychosis. The patients were divided into four groups according to duration of cannabis...

Ibogaine is a plant-derived alkaloid and dissociative psychedelic that demonstrates anti-addictive properties with several substances of abuse, including alcohol. 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) is a naturally occurring psychedelic known to occasion potent mystical-type experiences and also demonstrates anti-addictive properties. The potential therapeutic effects of both compounds...

Abstract Sexual function following 3,4-Methylenedioxymethamphetamine (MDMA, or ‘Ecstasy’) consumption was subjectively evaluated in 35 healthy recreational users (20 men and 15 women, aged 21–48 years) with regard to four major domains of sexual activity: desire, erection (lubrication in women), orgasm and satisfaction. Desire and satisfaction were moderately to profoundly increased by MDMA in...

The aim of this survey is to present an overview of research into psychopharmacology as regards the effects of different psychoactive drugs and neuroleptics (NL) on language in normal subjects and schizophrenic patients. Eighteen studies that have investigated the effects of different drugs (alcohol, amphetamines, secobarbital, L-dopa, psilocybin, ketamine, fenfluramine) and neuroleptics...

Clinical evidence suggests that hallucinogenic drug-induced altered states of consciousness (ASCs) and the incipient, acute stages of endogenous psychoses share many common phenomenological features. The aim of our study was to assess hallucinogen-like phenomena in endogenous psychotic patients using standardised methods. We examined 93 endogenous psychotic patients, 50 healthy controls and a...

In the context of the discovery of the cerebral ligand for the cannabis receptor, and the elucidation of its genetic sequence, we discuss the psychomimetic properties of Cannabis sativa, and explore the relationship between cannabis intoxication and mood. We suggest that renewed study of acute cannabis encephalopathy would be rewarding not only in deepening our understanding of consciousness in...
