“It’s really not about rock and roll anymore — it’s about rotten mold, and we have to let things rot.”

Want to hear an episode with the man Giuliana affectionately refers to as “Pablo?” Listen to my conversation with mycological mastermind Paul Stamets, in which we discuss fighting viruses with mycelium in a post-9/11 world, fending off carpenter ants with fungi, conquering a lifelong stutter with the assistance of Psilocybin cubensis, stacking microdoses of psilocybin with lion’s mane to treat neurodegenerative diseases like Alzheimer’s and Parkinson’s, and much more.
