Scientists just found that psilocybin (the active compound in magic mushrooms) helps people learn to stop craving cocaine without needing the usual relapse prevention therapy. Neuroscientists will now run 3+ new studies to figure out exactly which brain circuits make this work, because it's a genuinely novel mechanism that could unlock new addiction treatments.
The extinction-without-relapse split is a clean neuroscience puzzle — it separates learning consolidation from cue-reactivity circuitry. That is exactly the kind of mechanistic question that generates NIH R01 applications. The data is compelling enough to fund.
