9 Ss were requested to perceive simultaneously the taste of beer and a rhythmic sound, the pitch of which could be varied. The frequencies at which Ss experienced harmony between the taste and the sound were determined. At the pitch of harmony Ss reported characteristic experiences, e.g., optimum taste of the beer, rhythmic sensations in the head, and tickling sensations in the jaws and the...
The classical conditioning potential of several drugs was tested in rats by pairing a light CS with the drug UCSs; these stimuli were superimposed in a variable-interval 30 sec schedule for water reinforcement. Conditioning (suppression of bar-pressing in the presence of the CS) was definitely demonstrated with psilocybin (2.0 mg/kg), was suggested but not clearly shown with LSD (0.13 MG/kg),...
Given the controversy of the late 1960s and early 1970s over the possible induction of chromosomal damage by psycho-active agents like LSD and marihuana, the peyote study of Teplitz et al (p 299), is reassuring. It is, first of all, comforting to know that in vivo studies of agents that are possible chromosomal mutagens can produce, when properly designed and executed, clear-cut results....

In an operant situation pigeons learned to peck one response key 90 min after an injection of 0.25mg/kg delta9-tetrahydrocannabinol (delta9-THC) and another key when trained nondrugged. When tested with doses of delta9-THC lwer than the training dose the birds disciminated 0.20 mg/kg of the drug from the nondrugged state but not 0.15 mg/kg or lower doses. The animals were able to discriminate...
The effects of mescaline (3,4,5-trimethoxyphenylethylamine), a hallucinogen, can function as a discriminative stimulus in appropriately trained rats. As a test of the hypothesis that those pharmacologic properties which distinguish hallucinogens and non-hallucinogens in man are reflected in distinctive stimuli in rats, the present experiments examined the effects of...
To the Editor.— In a recent issue (229:763, 1974), Shaffer describes a series of cases characterized by anesthesia, analgesia, nystagmus, dizziness, diplopia, visual distortions, and psychosis. These findings were attributed to ketamine, a derivative of phencyclidine. Phencyclidine is a major component of street drug preparations.1In one series, phencyclidine was detected in 184 of 237 street...
The authors examine the development and effectiveness of a treatment program for alcoholism among American Indians. This program offers the alcoholic Indian both occupational and cultural therapy, including participation in the services of the Native American Church (peyote meetings). During these meetings, participants often ingest peyote (mescaline), which, like LSD, facilitates cathartic...
Room temperature fluorometric and low-temperature phosphorimetric analytical curves of hallucinogens in methanol/water solution have been prepared to demonstrate the absence of interference in common binary mixtures of hallucinogenic drugs. Limits of detection and linear dynamic ranges have been determined for drugs in mixtures. Mixtures containing LSD and another hallucinogen such as STP...
