Lysergic acid diethylamide: side effects and complications.

Lysergic Acid Diethylamide: Its Effects on a Male Asiatic Elephant.

A saline pond in a region in Antarctia where other lakes and ponds are frozen remains unfrozen at the prevailing low temperatures. The ecology of the pond is unique. A distinctive aerobic microbial population, though restricted to this natural habitat, adapts to growth in artificial culture. The growth habit of these organisms, as seen in nature and in laboratory culture, indicates a possible r...

Immunoassay analysis of lysergic acid diethylamide.

Screening large numbers of urine samples for drugs of abuse is typically accomplished using immunoassays that allow for processing large numbers of samples without the requirement of sample preparation before analysis. Until fairly recently, screening of lysergic acid diethylamide (LSD) in urine samples could only be accomplished by the use of radioimmunoassays (RIA). Recently, new nonisotopic ...

The paradoxical psychological effects of lysergic acid diethylamide (LSD).

BACKGROUND Lysergic acid diethylamide (LSD) is a potent serotonergic hallucinogen or psychedelic that modulates consciousness in a marked and novel way. This study sought to examine the acute and mid-term psychological effects of LSD in a controlled study. METHOD A total of 20 healthy volunteers participated in this within-subjects study. Participants received LSD (75 µg, intravenously) on on...

Interference with testing for lysergic acid diethylamide.

We found a high rate (4.2%) of positive results for lysergic acid diethylamide (LSD) by Emit in 1898 urine samples that were submitted primarily from psychiatric patients for drugs-of-abuse (DOA) testing. Specimens that tested positive for LSD by Emit subsequently tested negative for LSD with two RIAs. Furthermore, LSD was not detected in randomly selected Emit-positive urine samples by gas chr...
