    Traditional Use of Poppy in the Face of the Global Opioid Crisis

    The global crisis of synthetic opioids represents one of the most serious public health emergencies of our time. In countries such as the United States and Canada, the availability of fentanyl and its analogs—extremely potent and highly addictive—has overwhelmed public health systems. According to the UN and the WHO, more than 150,000 people die each year from opioid overdoses. In the U.S., deaths involving fentanyl mixed with stimulants rose from 235 in 2010 to over 34,000 in 2020.

    Iboga Community Engagement Initiative Phase 2 Report

    It is hard to walk a path you cannot see. A collective vision can serve as a guiding light, sup­porting community leaders, visionaries, practitioners, and policy-makers as we navigate through unknown terrain. It helps us remain focused on a future even though the exact path there is not yet fully illuminated. The purpose of the Iboga/ine Community Engagement Initiative was to engage with the global community to crowdsource opinions and ideas about what an ideal future looks like for iboga and ibogaine in global society.

    Plant Medicine Sourcing in Changing Times

    The sudden interruption of almost all maritime, air, and land travel worldwide due to the pandemic has opened the door for many communities to reflect on interdependences within a globalized world, particularly when it comes to “supply chains” for clothing, food, and plant medicines. One of the key impacts for communities that work with teacher plants (such as ayahuasca) outside of the Amazon has been the need to reconsider how they are procuring medicine for their ceremonies.

    Grief During Uncertain Times and the Future of Therapeutic Uses of Ayahuasca

    According to ICEERS associate researcher Débora González, grief is a form of love – it is the price paid for love. As we let go, of a person or of something held near and dear to our hearts, we grieve. It’s a natural and necessary process, not only for adapting to stressful times but also for personal growth and enrichment. And, while death may be the end of life from a biological perspective, what we’ve lost continues to exist after death, through our memories, thoughts, and even in our genes.
