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...

BACKGROUND: Validation of animal models of hallucinogenic drugs' subjective effects requires human data. Previous human studies used varied groups of subjects and assessment methods. Rating scales for hallucinogen effects emphasized psychodynamic principles or the drugs' dysphoric properties. We describe the subjective effects of graded doses of N,N-dimethyltryptamine (DMT), an endogenous...

Two persons are described who demonstrated prolonged neuropsychiatric syndromes after the ingestion of large doses of (+-)-3,4-methylenedioxymethamphetamine (MDMA), a recreationally used amphetamine analog. These cases suggest that MDMA, known to be neurotoxic to serotonin neurons in several experimental animals, may also produce untoward effects in humans. In addition, they provide evidence...

In rats tested during their first exposure to a Behavioral Pattern Monitor chamber, acute injections of the 5HT-2 agonists mescaline, quipazine, 2,5-dimethoxy-4-iodoamphetamine (DOI), 2,5-dimethoxy-4-methylamphetamine (DOM), or 2,5-dimethoxy-4-ethylamphetamine (DOET) produced an inhibition of locomotor and investigatory behavior during the first 30 min of the test session. This suppression of...

We have assayed several phenylalkylamine and indolealkylamine hallucinogens, as well as structurally similar nonhallucinogens, for their effect on human platelet shape change, a physiological model for the central serotonergic 5-HT2 receptor. The hallucinogenic drugs lysergic acid diethylamide (LSD-25), N,N-dimethyltryptamine (N,N-DMT), 5-methoxy-N,N-dimethyltryptamine (5-MeODMT),...

The stimulus properties of 3,4-methylenedioxyamphetamine (MDA), 3,4-methylenedioxymethamphetamine (MDMA) and several related compounds were compared to those of (+)-lysergic acid diethylamide (LSD) and mescaline (3,4,5-trimethoxyphenylethylamine) in a two-lever, water-reinforced, drug discrimination task. In animals trained to discriminate LSD (0.08 mg/kg) from saline (n = 8), LSD-like...

As previously reported, systemic administration of the hallucinogens D-lysergic acid diethylamide (LSD) (5-10 micrograms/kg) and mescaline (2 mg/kg) in the anesthetized rat produced a decrease in spontaneous activity but, paradoxically, facilitated activation of locus coeruleus (LC) neurons by sciatic nerve stimulation. In the present study, the hallucinogen 2,5-dimethoxy-4-methylamphetamine...

The hallucinogenic drugs represent a recurrent outbreak pattern with each generation or two seeming to rediscover their ego-dissolving effects. The inhalants produce a short-lived intoxication with certain volatile solvents affecting specific organ systems.

The use of naturally occurring and synthetically derived compounds for their "psychedelic" effects has been a part of human culture for thousands of years. The basic pharmacology of the major synthetic psychedelic compounds (primarily lysergic acid diethylamide [LSD]-25) is described and reference is made to their potentially beneficial psychological effects. Adverse reactions, defined as...

Previous studies from our laboratory have demonstrated that there are a number of important dissociations between the effects of hallucinogenic drugs on the activity of serotonin-containing dorsal raphe neurons and behavior in freely moving cats. In the present study, we extended this analysis to serotonergic units in the nucleus centralis superior (NCS) and nucleus raphe pallidus (RPA)....
