The final grant application period for 2026 closed on October 31. Applications will reopen in early 2027.

We invite proposals for studies that meet the criteria below. Each of these criteria must be a substantive element of the project to be considered for a grant.

Before applying or inquiring, please note:

• Indirect costs policy: the Etheridge Foundation does not support overhead / indirect costs (0% grant budget allocation).  

• Films, shows, and other media projects are not eligible for Etheridge Foundation grants.

• The size of our grants typically ranges from $10,000-$43,500, with rare exceptions for larger amounts.

Requirements

Our grants support projects that align with our mission through a focus on the following elements:

1) Comprise medical, clinical, or community healthcare studies or pilots by accredited institutions / investigators;

2) Are undertaken and directed by nonprofit institutions for the common good;

3) Utilize psychedelic therapies and/or traditional plant medicines and asses their impact;

4) Are focused on the treatment or prevention of opioid use disorder (OUD) and/or closely related conditions; and

5) Work with human participants, for ethical and relevant data – animal studies are not eligible.

In addition, grants are prioritized to studies that use integrative understandings of addiction which consider underlying causes and co-occurring mental health factors.

By invitation only, the Etheridge Foundation may occasionally award grants for novel projects beyond the above criteria that advance understanding of plant medicines and/or psychedelic therapies for treatment of opioid use disorder.
