Center for Medicinal Mindfulness



About Us


Established 2012 in Boulder, Colorado, Medicinal Mindfulness pioneered and became the first Cannabis-Assisted Psychotherapy, Psychedelic Therapy & Conscious Cannabis organization in the United States, and has since become an established leader in the emerging field of Psychedelic-Assisted Psychotherapy, and safe and legal Psychedelic Experiences.  

Medicinal Mindfulness is not just a psychedelic therapy clinic, we are an intentional psychedelic community that promotes safe and intentional psychedelic medicine use practices for personal and global healing and transformation.  

Medicinal Mindfulness integrates the four primary paradigms of psychedelic medicine use (the Creative, Scientific, Psychological & Spiritual) to elicit profound psychedelic healing and transformational experiences in a safe, legal and supportive environment. These experiences can be geared to individual sessions to support the transformation of trauma, PTSD, anxiety, depression, addiction and other emotional struggles. These experiences can also be used to explore the extreme growth edges of our human potential. They can also be shared in small groups, private retreats, or at our ongoing community programs, our Conscious Cannabis Events and twice monthly Community Breathwork with live music.

Our program is a safe space.  We are trauma informed, clinically trained, psychedelic activists, psychotherapists and healer-explorers. Our approach is Transpersonally-aligned, somatic (body-centered) and mindfulness based. Medicinal Mindfulness has helped establish professional psychedelic therapists and grassroots psychedelic communities in multiple cities in the United States and Canada. Our trained practitioners are actively facilitating psychedelic experiences in legal settings throughout the country.

Learn how to join the cutting-edge field of Psychedelic Therapy by attending Psychedelic Sitters School, the Medicinal Mindfulness Psychedelic Training Program.  PSS offers foundational courses in psychedelic harm reduction, safe psychedelic sitting and crisis intervention, the use of cannabis as a psychedelic medicine, Psychedelic Guide Training, Psychedelic Group Facilitation, and others. Our local psychedelic apprenticeship program provides hands-on experience for becoming a professional Community Breathwork Facilitator, Psychedelic Cannabis Sitter & Guide, and Group Psychedelic Facilitator. The program is designed for new and advanced practitioners, and is in a retreat setting to support out of town participants.

In addition, we sponsor and organize educational events such as the Psychedelic Shine Speaker Series and Community Gatherings, and facilitate community outreach with other psychedelic communities, programs and organizations.     

The Extended-State DMT Program completed its first DMTx Psychonaut Training in September 2018, and is currently initiating Phase 2 of the research.

Joe D.

of Nibumbu, Lead Music Facilitator

+ About Joe

In 2001, Joe nearly perished in a car accident. The long recovery process nurtured a healer’s spirit within him, and as his wounds healed, his soul yearned for ways of channeling this ever-growing impulse. Eleven years later, in 2012, Joe was still searching for his life’s calling when some friends invited him to come along with them to a music festival.

One of the musical performances had such a potent effect on him that by the end of the night, the direction of his entire life would be changed forever: he would become a musician...or die trying. In 2013, his new calling would bring him all the way from Florida to the Rocky Mountains, where he found fertile ground for nurturing his musical inclinations. Shortly thereafter he connected with groups of like-minded individuals and out of that substrate of community and nature, he co-founded Nibumbu (, and thus an ideal vehicle for harnessing his creative and healing impulses.

Joe’s ever growing list of Instruments: Acoustic drum kit, 3+ types of electronic drum systems, Didgeridoo, Loop pedals, Hang drums/Handpans, Jaw Harps/Danmoi, hand drums and various types of percussion instruments.


Craig S. MA, LPC, LAC

Licensed Professional Counselor

Licensed Addiction Counselor

+ About Craig

I am interested in blending the evidenced-based practices of Western psychotherapy with the wisdom and compassion of Eastern psychology. Utilizing mindfulness practices and depth psychotherapy, I focus on bringing openness, curiosity, and compassion to the parts of ourselves that generate fear, resistance, and trepidation. Often, symptoms of pain and suffering arise from shadow areas that require more light and compassionate attention. I value psychotherapy as a safe space to begin doing this deep personal work with guidance, support, and care.

I have been interested in substances and psychedelic psychotherapy since a young age. Inspired by the psychedelic research of Rick Strassman, I pursued a career in understanding both the wisdom and neurosis of various mind-altering substances. This path took me down a road of working directly with addiction, trauma, and spirituality. I became a Licensed Addiction Counselor in 2015 and have explored how substances can both heal and devastate. I have become passionate about exploring ways to utilize psychedelic medicines for growth and expansion, while reducing the potential for harm. My end goal is to support healthy relationships towards ourselves, towards others, and towards the medicines we choose for personal growth.

Justin F.

of Nibumbu, Lead Music Facilitator

+ About Justin

Justin is a musician and artist who picked up his first instrument at the age of 4. Justin was raised on the west coast in southern California and moved to Colorado at the age of 13 with his family. Over the years, family trauma, addiction and long hours working on the road as a contractor put his artistic output on hold. A traumatic injury on the job in his mid-twenties forced him to rethink his career path. Fortunately it created enough space in his life for art and music to reemerge and mark the start of his healing journey.

Now in his mid 30’s, he’s fully focused on his artistic passions including tattoo, music in many forms, visual art, and a combination of all of the skills he’s picked up along the way, allowing him to come into his true purpose. Always evolving and years of work with entheogens made stepping into sound healing a wonderful and natural match for Justin. Grateful to be a part of people’s healing process, he also uses his music and this opportunity to heal himself in the process. Justin co-founded Nibumbu (, with Joe D.

Mark Braunstein, D.O., ABPN

Cannabis Psychiatrist

+ About Dr. Braunstein

Dr. Mark Braunstein, DO, is a child, adolescent, and adult psychiatrist with a background in wilderness psychiatry, osteopathic medicine, cannabis psychiatry and a passion for helping people to use less psychiatric medication.

He has been in the trenches treating serious mental illness since graduating medical school in 1997. Dr. B., as referred to by patients and colleagues, started his psychiatry career working in the jails of New Mexico. From there, he treated severely mentally ill patients in the state hospitals of Main. Moving to Colorado in 2002 he started his private practice and began combining cannabis medicine with psychiatry.

Not long after, he was sought out to work for a wilderness therapy treatment center. He was not only essential in combining the fields of psychiatry and wilderness therapy, but pioneered a new way to treat patients in this realm. He created a industry-specific model that others now follow. While working with patients who were spending three months at a time in the wilderness, he found they were coming in overmedicated and leaving very well on none, or at least, much less medication. A large part of this due to the powerful combination of wilderness therapy, coupled with integrative and holistic medicine and Dr. B.’s unique treatment style. His uncanny knack for creating a safe space for patients to be honest and raw, have yielded unmatched results. Educating his patients on issues and medications while infusing a collaborative approach, have been catalysts for empowering his patients to become better advocates for their own health and wellbeing.

Witnessing these results spurned a passion for helping people outside of wilderness therapy to minimize or stop their psychiatric medications via other modalities of healing, including medical cannabis. Over the past sixteen years of practice, he has treated over ten thousand people with medical cannabis. He now specializes in treating psychiatric disorders with medical cannabis, adjusting their dosages and changing formulations, using an evidenced-based approach to cannabinoid science in prescribing marijuana as a medicinal treatment.



Extended-State DMT & Conscious Cannabis Research


The Medicinal Mindfulness Extended-State DMT program (DMTx)  was initiated in February 2016 by Daniel McQueen, co-founder of Medicinal Mindfulness. DMTx is based on the cutting edge pharmacokinetic research of Dr. Andrew Gallimore and the revolutionary DMT research of Dr. Rick Strassman. Our DMTx program explores legal psychedelic research and exploration opportunities that are congruent with the needs and interests of the psychedelic community. 

Potential applications of Extended-State DMT experiences seem limitless: therapeutic healing, advanced creative problem-solving, consciousness exploration, and explorations in the nature of reality itself.   

It is because of the importance of this work that all of us at Medicinal Mindfulness wish to share what we are learning with the international psychedelic community and to bring our community into the creation and implementation process of this psychedelic inspired program.



Psychedelic Shine Speaker Series & Other Media

Since 2016, the Center of Medicinal Mindfulness has produced an ongoing psychedelic speaker series and community event called Psychedelic Shine.  Our largest event featured Dr. Dennis McKenna at the Boulder Theater in 2017. We’ve also hosted Dr. Rick Strassman, and Dr. Andrew Gallimore to discuss their work on DMT, among many local activist, researchers and practitioners.  We’ll do this again in the near future, but no events are currently planned.
