00:08

In April 1943, Swiss chemist Albert Hofmann accidentally exposed himself to a drug he derived from ergot fungus and recorded its unexpected, mind-altering effects.

00:20

The drug, lysergic acid diethylamide— or LSD— was soon heralded for its psychiatric potential.

00:28

But how do LSD and other psychedelic drugs affect the body?

00:32

And can they actually be medicinal? Psychedelics are a class of drugs that alter mood, cognition, and perception, often triggering unusual states of consciousness like hallucinations.

00:44

They all interact with the body's serotonin neurotransmitter system, which regulates many processes, including mood, sleep-wake cycles, appetite, and memory.

00:53

Lower rates of serotonin signaling are associated with impaired sleep and attention and diminished responses to positive information.

01:02

Meanwhile, higher rates tend to track with more positive moods and greater emotional stability.

01:08

All psychedelic drugs increase the amount of serotonin signaling.

01:12

However, they interact with the serotonin system in different ways and affect other neurotransmitter systems, all of which determines their unique effects and medical potential.
