How do you know if a mouse is on a psychedelic? It might just shake its head. This behavior, known as the head-twitch response, signals whether a molecule is a psychedelic-like hallucinogen.

Was it DMT? Or was it heaven?
When a neurosurgeon claimed he glimpsed the afterlife during a coma, skeptics offered a more earthly interpretation – a surge of DMT produced by his own body. Was his tale of eternity a trick of the brain, or a window into something science can’t explain?

In Altered States, host Arielle Duhaime-Ross explores how people are taking these drugs, who has access to them, how they're regulated, who stands to profit, and what these substances might offer us as individuals and as a society.
