This study compared the frequency and types of dissociative experiences reported by detoxified alcoholics and drug abusers, and examined the relationship between dissociation and recent and lifetime use of alcohol, cannabis, cocaine, and heroin. One hundred thirty-eight self-referred male veterans detoxified from alcohol (N=62) and drugs (N=76) on inpatient units at a Veterans Affairs hospital...

Whether or not drug use can cause a chronic psychotic disorder that is clinically similar to schizophrenia and related disorders is an important question. In this review, the authors attempt to determine whether there is enough evidence in the literature to support the notion that illicit drug use can cause chronic psychotic disorders. They conclude the literature strongly suggests that a...

The purpose of the present study was to investigate the disruptive effects of cannabinoids on working memory as assessed in the eight-arm radial-maze. Systemic administration of delta 9-THC, WIN-55,212-2, and CP-55,940 increased the number of errors committed in the radial-maze. CP-55,940 was the most potent cannabinoid in impairing memory (ED50 = 0.13 mg/kg). delta 9-THC and WIN-55,212-2...

CP 55,940 is a potent synthetic bicyclic cannabinoid analog that has been used in a number of studies as a radioligand for the cannabinoid receptor. This compound shares behavioral and biochemical properties with naturally occurring cannabinoids such as delta 9-THC. The purpose of the present study was 3-fold: to establish the ability of CP 55,940 to serve as a discriminative stimulus, to...

We conducted a random survey of illicit drug use by undergraduate students at a private southern university in 1990 and compared the results with results from a similar 1986 survey of that college's student population. During the 4 years since the first study, the prevalence of cocaine use declined from 39% to 21%, and use of traditional amphetamines declined from 22% to 12%. No significant...

SOME EFFECTS OF GROUP DRUG TAKING ERWIN DI CYAN* The purpose of this paper is to discuss briefly some aspects of the differences between drug effects when drugs are used in groups as distinguished from their solitary use. The human organism responds to a variety of stimuli. Its response to signals may be physiological or psychological. The latter response includes recollections by (a) retrieval...

To the Editor. —We have recently presented data 1 from our annual survey of 522 328 junior and senior school students from schools across the United States. This anonymous questionnaire on the prevalence of drug use was administered to all junior and senior students attending home rooms in these schools in 1993, and results were compared with 1992. Hallucinogen use increased significantly ( P t...

Salvia divinorum is a vision-inducing mint used by the Mazatec people of Oaxaca, Mexico. It is grown in California and other parts of the United States where it is employed as a legal hallucinogen. Traditional opinion has been that the plant has mild psychotropic activity, at best. However, when ingested in the correct manner, it is quite powerful. The fresh leaves are chewed as a quid and kept...

Abstract As part of a larger survey of health‐related behaviours, 2239 15–16‐year‐olds in Wales provided information on their use of eight different types of drugs. Key findings indicate that just over a fifth of this age group report to having tried drugs at some time, while a tenth say they have done so within the past month. The most frequently reported substances were marijuana, solvents...

[3H]CP 55,940, a radiolabeled synthetic cannabinoid, which is 10-100 times more potent in vivo than delta 9-tetrahydrocannabinol, was used to characterize and localize a specific cannabinoid receptor in brain sections. The potencies of a series of natural and synthetic cannabinoids as competitors of [3H]CP 55,940 binding correlated closely with their relative potencies in several biological...
