The Etheridge Foundation assesses grants on a rolling basis. The size of our grants typically ranges from $10,000-$43,500, with rare exceptions for larger amounts.

Our submission cycle is currently CLOSED. The grant application will reopen from July 10 - August 31, 2026 and October 1 - November 30, 2026.

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.

Requirements

Please note: Films, shows, and other media projects are not eligible.

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

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

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

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

4) For 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 (no animal studies).

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

Indirect costs policy: we do not support overhead / indirect costs at this time (0% grant budget allocation).  

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.
