Final answer:
The psychological effects of LSD were first reported by Albert Hofmann, a Swiss chemist who discovered the effects after accidentally absorbing the drug.
Step-by-step explanation:
The psychological effects of LSD were first reported by Albert Hofmann, the Swiss chemist who developed the drug. LSD, or d-lysergic acid diethylamide, is one of the most potent hallucinogenic drugs.
Hofmann accidentally discovered its psychedelic effects in 1943 when he absorbed a small amount through his skin.
LSD was synthesized from lysergic acid, a compound derived from a rye fungus, and is known for its mood and perception-altering properties.
