      <Desc>1. DrugsData Lab Drug Checking -- Erowid Center runs a laboratory drug checking program that analyzes the contents of street samples of psychoactive drugs, including: novel psychoactive substances (NPS); stimulants and euphoric stimulants; psychedelics; research chemicals; street heroin; fentanyl; and other opioids; as well as commercial and counterfeit pharmaceuticals. Samples are tested at a licensed laboratory and the results are published online at DrugsData.org. Erowid's DrugsData project also collects, manages, reviews, and presents laboratory-testing results from other US and international organizations. This information is made publicly available to help harm-reduction efforts, medical personnel, researchers, and the public. In 2023, 2,396 samples were tested through this project and 250 unique substances were detected. These results were published alongside 982 samples tested by other organizations. An average of 35,000 result pages were viewed per day, with an average 14,000 unique visitors per day. Results were regularly published on social media to Erowid's more than 180,000 followers. Erowid continued its partnerships with research groups doing lab validation of on-site analytical tools such as compact FTIR and fentanyl and xylazine test strips. A portion of the expenses and revenue associated with DrugsData research are included in the Drug Trend &amp; Novel Psychoactive Substance and Research program services described below.</Desc>

        <Desc>2. Public Online Information Services -- Erowid Center develops, maintains, and provides free access to an online collection of more than 96,500 documents, images, and other media files related to psychoactive plants and drugs. The collection contains information, essays and articles authored by a broad spectrum of contributors including health care professionals, substance abuse counselors, toxicologists, chemists, therapists, law enforcement agents, lawyers, anthropologists, experiential experts, writers, media, educators, and the general public. Note that Erowid's Experience Reports project is tracked as a separate program service. Erowid also shared information via social media accounts on Twitter, Instagram, and Facebook.</Desc>

        <Desc>3. Archiving of Historical Documents -- Erowid Center's mission includes collecting, organizing, and preserving resources about psychoactives for the historical record. In 2023, Erowid's primary document archiving project was the Shulgin Collection. Erowid made great progress in digitizing Alexander and Ann Shulgin's personal papers, audio recordings, and documents. Erowid also organized, identified, and created metadata for digitized files. By the end of the year, Erowid had created index entries for 35,000 scanned documents in the collection of around 200,000 total scanned items. Erowid Center maintains a physical space designed to allow processing of historical archive collections (organizing, scanning, photographing, and digitizing) as well as permanent storage of some library archives/collections.</Desc>

        <Desc>4. Research, Surveys, &amp; Research Improvement -- In 2023, Erowid co-authored 1 published peer-reviewed journal article. We participated in writing and submitting two additional papers, not published in 2023. We worked on multiple scientific/medical research projects as part of the Lab Validation subproject of our DrugsData program. Erowid improves scientific, medical, and sociological information about psychoactive substances and those who use them by promoting participation in studies and surveys produced by academics, educational institutions, and related organizations. Erowid works directly with scientists-in areas where we have specialized knowledge-to help design credible studies and provide editing, reviewing, and fact-checking for resulting academic publications. Erowid Center's resources are referenced in hundreds of journal articles, books, and media articles each year</Desc>

        <Desc>5. Drug Trend &amp; Novel Psychoactive Substance Tracking -- Tracking new psychoactive medicines, technologies, research chemicals, psychedelics, and novel psychoactive substances (NPS) is one of Erowid Center's areas of expertise. With the objective of educating the public on the risks and benefits associated with emerging drugs, we 1) monitor the availability, use patterns, and effects of these substances through consultation with volunteers, allied organizations, medical professionals, submissions, and online forums; 2) analyze psychoactive chemicals through our DrugsData program (tracked as a separate project); 3) coordinate between experts and researchers in the field; 4) educate writers and authors for media, news, and books; and 5) publish information about these substances, online and in print. In 2023, Erowid's DrugsData encountered 48 unidentifiable novel substances in submitted samples. With the help of a network of international experts, we were able to identify 24 of these. Erowid worked with multiple groups to monitor the contents of street 'heroin'/down/dope/fentanyl as well as cocaine and methamphetamine. Erowid helped identify and characterize contaminants, synthesis byproducts, and novel substances. We leveraged our expertise to help develop systems designed to mitigate the societal damage of the "opioid epidemic".</Desc>

        <Desc>6. Education and Educational Materials, Books, and Gifts -- Erowid provided direct education services by answering online questions from the public via email, social media, and other communication systems. Erowid maintains a social media presence via Instagram, Twitter, Facebook, and LinkedIn through which we publish new information, drug checking results, news and research updates, and answer questions related to psychoactives. We distribute books, handouts, and teaching materials about psychoactive drugs, plants, practices, and technologies to members and the general public, furthering our educational mission.</Desc>

        <Desc>7. Experience Reports Collection -- Erowid Center solicited, reviewed, and published first-hand reports of people's experiences with psychoactive plants, drugs, and technologies. Erowid's Experience Reports generated information about novel and classic psychoactive materials as well as aggregate data about why and how people use psychoactives, both for current factual documentation and for the historical record. Researchers, academics, medical professionals, and the public use the results for educational purposes and as data for peer-reviewed articles and publications. Reports are reviewed and edited before being published. Trained volunteers perform a portion of the work under the supervision of Erowid staff. In 2023, Erowid crew completed 3,750 "triages" (reading and rating an experience report), review-edited for publication 548, and published 444, ending the year with 42,279 published reports in the collection covering 886 substances. Approximately 21 million experience reports were viewed during the year.</Desc>

        <Desc>8. Events &amp; Conferences -- Erowid conducts educational outreach in person and online at conferences, seminars, festivals, and meetings. In 2023, we had monthly technical meetings with research partners monitoring street drug contents and contaminants as part of our DrugsData project. Erowid Center had a booth at the Psychedelic Science convention in Denver Colorado, with six Erowid crew members working the booth. Erowid gave one formal presentation at that convention. We also spoke at two events, one a course at UC Berkeley and one Shulgin-related, as well as attending two additional Shulgin related events.</Desc>

Information Network - EEN -- Erowid Center works with a network of both professionally trained and self-taught experts with knowledge about psychoactive plants, chemicals, and technologies. Erowid Expert Network (EEN) members volunteer to share their expertise for the purpose of educating the public and improving the quality of information about this topic. The EEN facilitates making connections between those who are seeking information and experts who can help them. This furthers Erowid Center's mission by helping to improve both internal and external educational resources through increased fact checking and review.</Desc>

A complete digital version and constituent articles are later published online for free access by the general public. More than 15,000 copies of previous issues of Erowid Extracts were viewed/downloaded in 2023, and thousands of people read individual articles from previous issues online. Back issues were also distributed worldwide for free to related organizations, members, and events.</Desc>

        <ExplanationTxt>Erowid Center has diverse volunteers, from senior researchers to policy makers, health care workers to professors, informed parents to harm-reduction workers, college-age drug geeks, and followers on social media who help us out with their particular areas of expertise. In 2023, Erowid Center had more than 1,700 volunteers on its volunteer email list, 274 volunteer content reviewers, and 35 active Experience Report volunteers, with dozens more available when asked or needed. Volunteers reviewed and edited content, found and summarized news stories relevant to our educational mission, tracked drug trends, entered drug checking results, worked to identify unknown substances, helped with archiving projects, visited physical libraries to locate reference materials, and triaged or reviewed Experience Reports. Erowid volunteers contributed more than 1,000 combined hours, though we do not ask volunteers to document their time.</ExplanationTxt>

        <ExplanationTxt>Erowid Center's Conflict of Interest policy covers the officers and Board members of the organization and their families. Every transaction of the organization is reviewed and approved by the Treasurer. The Treasurer reviews any payment to any Board member or key employee for conflicts of interest. Any transactions that might entail a conflict of interest is reviewed by the Board of Directors (minus any interested member). For transactions that involve the Treasurer, such as salary or reimbursement of unusual expenses, approval is sought from an independent committee of the Board. Members of Erowid Center's Board are asked to confirm annually that they comply with this policy.</ExplanationTxt>

        <ExplanationTxt>All officers' salaries and compensation are decided solely by independent members of the Board of Directors based on contemporaneous comparability data for similar positions at similarly situated organizations. The most recent increase in annual compensation for the officers (and other key employees) was in 2022 when they were adjusted for inflation with the approval of an independent committee of the Board of Directors.</ExplanationTxt>
