...   Finance & Accountability

Charity Navigator evaluates a nonprofit organization’s financial health including measures of stability, efficiency and sustainability. We also track accountability and transparency policies to ensure the good governance and integrity of the organization.

No Score

We have not issued this nonprofit an Finance & Accountability score. This does not indicate a positive or negative assessment, only that we have not reached a conclusion for the following reason:

This organization cannot be evaluated by our Encompass Rating methodology because it does not e-file IRS Form 990

To ensure year-to-year consistency, the Encompass Rating System’s Finance & Accountability beacon analyzes the three-year average of some data provided through the IRS Form 990.
Charity Navigator does not currently have the data required from e-filed IRS Forms 990 for Erowid Center under the EIN: 20-3256212. 
This indicates that Erowid Center may still be filing paper Forms 990.

The lack of a rating for this reason simply means that the organization does not meet our rating criteria. It does not indicate a positive or negative assessment by Charity Navigator.

...   Impact & Results

Charity Navigator assesses how well a nonprofit delivers on its mission. To issue an Impact & Results score, we estimate the actual impact a nonprofit has on the lives of those it serves, and determine whether it is making good use of donor resources to achieve that impact.

No Score

We have not issued this nonprofit an Impact & Results score. This does not indicate a positive or negative assessment, only that we have not reached a conclusion for one of the following reasons:

  • The nonprofit is eligible for a score, but we have not yet gotten to scoring it.

  • The nonprofit is eligible for a score, but we have not yet developed the specific algorithms to estimate the impact of the type of service it delivers and so cannot issue a score yet.

  • The nonprofit does not primarily deliver services directly to beneficiaries or it is not reasonable to expect the nonprofit to measure impact for its primary activity. The impact analysis framework that we use is not well suited to these nonprofits.

  • The nonprofit is not heavily reliant on individual donors because beneficiaries fund a majority of its costs or it does not receive any private charitable contributions.

What is your organization aiming to accomplish?

Erowid Center 's mission is to develop and provide access to accurate information about psychoactive plants, chemicals, pharmaceuticals , and technologies in order to educate, improve health, and encourage beneficial cultural reform. Erowid is dedicated to helping both the public and professionals educate themselves about psychoactive drugs.

What are your strategies for making this happen?

Erowid Center directly educates the public about psychoactive substances—from legal caffeinated beverages to prescription pharmaceutical painkillers to illegal psilocybin-containing mushrooms. We also inform educators, including teachers, physicians, harm-reduction organizations, and community information hubs...in order to spread accurate information widely.

What are your organization's capabilities for doing this?

Our flagship project, Erowid.org, has evolved into a trusted global information hub. Because of our long track record and established rapport with diverse communities, people worldwide contribute articles, photographs, experience reports, and timely alerts about medical and law enforcement events. We actively gather the latest data directly from individual psychoactive drug users. We also track and compile current research and legislation. Since 1995, we have collected tens of thousands of pages of documents covering the history, science, and culture of these substances. The result is the world's most trusted public resource about psychoactive drugs and how people use them.

How will your organization know if you are making progress?

Erowid Center receives 75% of its support from the public, greatly exceeding the IRS's public support test requirement of 33.3%. We serve information to more than 16 million people each year on a small budget. Each $1,000 donation provides information to 50,000 people. In 2011, the Drug Policy Alliance selected Earth and Fire Erowid as the recipients of the Dr. Andrew Weil Award for Achievement in the Field of Drug Education. They lecture worldwide on topics related to the use and effects of psychoactive drugs. Erowid has been a GreatNonprofits "top-rated nonprofit" every years from 2012 through 2019.

What have and haven't you accomplished so far?

Erowid's resources undoubtedly save lives. In fact, this is one of the most frequent pieces of feedback we receive. In recognition of this, Erowid Center received a “Top Health Nonprofit" award from GreatNonprofits in each of the last three years. One of our most influential projects is the Experience Vaults, where we have compiled over 100,000 first-hand descriptions of the recreational use of psychoactive drugs. The collection receives over 100,000 views per day. Erowid also operates the only program in the United States with DEA permission to conduct testing of anonymously submitted controlled substances.
