Empty bottles of alcohol, for article on psilocybin-assisted therapy

First-of-its-kind study reveals how psilocybin helps treat alcohol dependence

Psilocybin-assisted therapy helped 13 people who had struggled with heavy drinking reach the root of what they were drinking to escape, according to new interviews published in Psychology of Addictive Behaviors. Participants described years of self-blame and isolation quieting after their sessions, replaced by something many had never felt toward themselves: compassion. They credited the trained therapists and carefully held setting as much as the medicine itself, calling both essential to feeling safe enough to face old pain. The researchers are honest about the study’s limits, including a mostly white, higher-income participant group. Still, as Oregon and Colorado open legal pathways, these first-person accounts offer a hopeful glimpse of how psychedelic care might one day reach the communities who need healing most.

Minnesota becomes 23rd U.S. state to legalize recreational marijuana

Minnesota’s new cannabis law will automatically clear tens of thousands of low-level marijuana convictions, pairing legalization with one of the most ambitious record-clearing efforts in the country. Adults 21 and older can now possess cannabis under the law Gov. Tim Walz signed in May 2023, making Minnesota the 23rd state to legalize recreational use. What sets it apart is the justice piece: people don’t have to navigate courts to clear their records — the state does it for them, opening doors to jobs, housing, and education long blocked by old convictions. As legalization spreads, Minnesota offers a model that finally asks who bore the costs of prohibition, and who deserves a fresh start.

New program to restore 120 miles of coral reefs off Big Island of Hawai’i

Coral reef restoration along Hawaiʻi’s Big Island just got a serious boost: a new $25 million initiative called Ākoʻakoʻa is taking on 120 miles of degraded reef off the Kona coast. The name means both “coral” and “to assemble,” and that’s the whole idea — marine scientists, Native Hawaiian practitioners, state agencies, and local nonprofits working as one. A new propagation facility in Kailua-Kona will grow heat-resilient corals while researchers test what helps reefs bounce back. Guiding it all is the Hawaiian principle of Mālama I Ka ʻĀina, caring for the land so the ocean can thrive. With reefs in trouble worldwide, this kind of partnership — Indigenous wisdom and Western science as equals — is a model other coastal communities will want to watch.
