A conference all about psychedelics wrapped up at the Colorado Convention Center in Denver last week. More than 4,000 people attended Psychedelic Science 2025: The Integration. The fifth edition of the conference was hosted by The Multidisciplinary Association for Psychedelic Studies (MAPS) in Denver for the second time after visiting in 2023.
The event brought together academics, scientists, policy makers, politicians, artists and advocates from around the world to discuss research, best practices, campaigns, business, culture, community building and more. This year’s theme was “integration” — a play on words referencing how people integrate psychedelics lessons and experiences into their day-to-day lives after a trip — now that psychedelics have become legal in multiple states.
“If your deepest dreams are something that you can accomplish in your own lifetime, they're too small.”
MAPS Founder and CEO Rick Doblin, on generational change and honoring people that came before him
The Exposition Hall had something for just about everyone
The market, like a sea of vendors, included small businesses and startups, universities recruiting students and hawking their latest research, non-profits and community orgs, meditation and wellness stations.


“I've sort of been exploring psychedelics for a while, and I feel like a lot of my experience with psychedelics has been sort of like the cultural zeitgeist around it. And I think this is a really good opportunity to sort of explore the more scientific and empirical side to things. And I really want to sort of flesh out my understanding of psychedelics in that realm.”
Jake Ziegler, Colorado resident and convention attendee

“If you're on psychedelics and you're listening to music, this brings you in your body and deepens the musical experience and deepens the psychedelic experience.”
Ben Aldern with Crescendo Tactile Beds
“It's absolutely heartwarming and a breath of fresh air a hundred percent with everything that we are experiencing in the world. It's so beautiful to know that this community exists.”

CPR sits down with …
Rick Doblin, the founder of the Multidisciplinary Association for Psychedelic Studies. He spoke with Colorado Matters host Ryan Warner about the future of psilocybin in states like Colorado, his belief that psychedelic treatment should include both the drug and therapy, MDMA’s setback with FDA approval, and more.
“The highest cost is depression, is substance abuse. The highest promise is that you can treat some of the hardest cases, people who have not been able to make much progress with the currently available medications, the currently available psychotherapies.”
Rick Dublin on the greatest promise of psilocybin in Colorado’s Healing Centers

“(Treatment-resistant depression) puts the blame on the person. The person is resistant to the treatment. It’s not, ‘(The treatment) didn't work.’ It's not, ‘it’s ineffective.’ You're the problem. The patient is resistant to the treatment. That's what some of the people that have developed some of these treatments say, ‘Oh, my treatment works for everybody unless the patient's resistant.’”
Rick Dublin on conventional depression treatments and the promise of psychedelics to break through

Retired Navy SEAL Diego Ugalde and retired deputy sheriff Rob Poynter at Plant Magic Cafe. They sat down with CPR’s Haylee May to discuss their use of psychedelics and storytelling to heal PTSD in veterans and first responders. Diego started the Warrior Side project, which helps first responders and veterans find a meaningful way to talk about their difficult experiences and healing journeys. Poynter started the Siren Project, which helps first responders connect with psychedelics safely. They shared their stories at Plant Magic Cafe in Denver.

“Warrior Side is a conscious approach to storytelling… I know a million veterans who have stories that every single time they tell it, it's like drinking a shot glass of poison.It's rooted in egoic attachment, it's rooted in shame, it's rooted in anger. They haven't necessarily healed or processed or transformed… We can start to tell the story through a healing perspective.”
Diego Ugalde

“I am putting myself out there because I want people to see that, hey, this is a former deputy sheriff, fairly conservative guy. I've done psychedelics. I'm not crazy. My brain is not fried.”
Rob Poytner



The main stage
For a week, the convention center was buzzing with lectures on the latest research, mindful meditation sessions and even keynote speakers like Gov. Jared Polis, former Gov. Rick Perry of Texas, and retired NFL players.
“The idea is to create a regulatory structure that allows for the legal and safe use of natural medicines. This is something that the United States of America writ large has a lot to learn about. And in Colorado we are innovators.”
State Attorney General Phil Weiser, who was the conference’s opening keynote speaker
Pull quote: “Granting these pardons is an important step forward, of course, for the individuals. We'll now have this cleared from their record, but also to really acknowledge the error in public policy that led to their conviction, creating a more just system to break down barriers and help them move on with their lives,” — Gov. Jared Polis after granting a mass pardon of people convicted of state psilocybin and psilocin charges.

“My reputation is not worth more than their lives.”
Former Texas Governor Rick Perry, when told he would risk 40 years of conservative credentials if he backed psychedelic therapy for veterans
