The Problem

Problem Statement

The drug overdose epidemic has become a national crisis, with over a million Americans dying from overdoses since 1999, and opioids contributing to over 70% of these deaths. Current harm reduction strategies face challenges such as lack of funding, fragmentation, cultural dissonance, underutilization of technology, and lack of inclusivity.

Expansion: Drug Overdose Epidemic

Magnitude of the Crisis

The drug overdose epidemic in the United States has escalated to unprecedented levels, claiming over a million lives since 1999, with more than 112,000 deaths reported in the last year alone. Alarmingly, drug overdoses have become the leading cause of death for individuals aged 18-45 in the country.

Role of Opioids

Opioid drugs, including prescription pain pills, heroin, and synthetic opioids like fentanyl, contribute to over 70% of these overdose deaths. Fentanyl, in particular, has emerged as the most deadly synthetic opioid, often concealed in recreational drugs and even infiltrating the legal prescription market through illicit channels.

Demographic Impact

In 2023, drug use was most prevalent among individuals aged 18-29, constituting roughly 73% of drug users in America. Engaging with this demographic is critical to addressing and mitigating the drug overdose crisis.

Comparative Strategies

Historically, public health crises like the HIV epidemic saw significant reductions through innovative products and behavioral shifts, such as increased condom use over three decades. Similar approaches are needed to bend the curve of the overdose epidemic, focusing on public perception, preparedness, access to anti-overdose products, treatment, and support infrastructure.

Existing Challenges and Inefficiencies

Despite the severity of the crisis, current harm reduction strategies face significant challenges that hinder their effectiveness:

  • 1. Lack of Funding and Infrastructure: The current sector attacking this problem lacks substantial funding and infrastructure support, with most organizations operating on shoestring budgets and limited resources.
  • 2. Fragmentation and Lack of Cohesion: Unlike other social impact areas with well-established anchor organizations, the current response network lacks a unified, national leader. The landscape is highly fragmented, with small groups operating independently and often duplicating efforts.
  • 3. Cultural and Operational Dissonance: Many response organizations operate with autonomy, sometimes isolating themselves from potential allies and resources due to systemic biases and lack of collaboration.
  • 4. Technological and Social Media Engagement: There's a notable gap in leveraging modern technology and social media platforms to engage broader audiences, particularly the younger demographic most at risk.
  • 5. Representation and Inclusivity: The current movement primarily focuses on a narrow segment of drug users, excluding a more diverse range of individuals who are also at risk of overdose. This limited focus reinforces stigma and fails to address the broader spectrum of needs within the population.

Our Solution

Call to Action

Addressing the drug overdose epidemic requires a comprehensive approach that tackles these systemic challenges, builds cohesion and collaboration, secures adequate funding and resources, leverages technology effectively, and ensures inclusivity and representation across the spectrum of drug use in the United States. End Overdose seeks to fill these gaps and lead a concerted effort to end overdoses through innovative, coordinated, and inclusive strategies.

  • Public Education and Awareness: Implement public education campaigns, access to naloxone and test strips, and immediate access to addiction treatment.
  • Resource Allocation: Establish operational hubs, connect organizations, and identify innovative approaches.

Our History

Theo Krzywicki


Theo Krzywicki's innovative leadership as the founder and CEO of End Overdose, combined with his extensive experience as a firefighter/paramedic, has been pivotal in transforming the public health landscape through pioneering strategies in overdose prevention and response education. His firsthand insights from emergency response scenarios have been crucial in developing training programs that equip individuals with the knowledge and skills to act quickly and effectively in overdose emergencies.

Under Theo's direction, End Overdose has launched impactful messaging campaigns that ensure the organization's initiatives are not only external efforts, but integral parts of the communities they serve. A cornerstone of these efforts is an online training platform that employs social media to captivate and educate its audience. He’s also evolved End Overdose’s outreach into the music scene, public schools, college campuses, and other key points of connection. This comprehensive strategy led to significant achievements in 2023, including the training of over 216,000 individuals in overdose response, the distribution of 166,000 doses of naloxone, and founding 30 End Overdose chapters nationwide. With Theo at the helm, End Overdose continues to make substantial strides towards mitigating the opioid crisis through a blend of education, advocacy, and solutions.

Theo connected with Ryan Hampton, an influential advocate, speaker, author, and media commentator in America's addiction recovery advocacy and drug policy reform movements. Hampton is a former member of the Clinton White House and part of the core team that released the first-ever U.S. Surgeon General's report on alcohol, drugs, and health in 2016.

Theo collaborated with Ryan Hampton to provide a Facebook live training on how to use naloxone for a Mobilize Recovery event. As a paramedic in Riverside County, Theo was urged to start his own nonprofit to simplify training for individuals. Thus, End Overdose was initially created to provide Narcan training for drug treatment centers and sober living homes in Southern California, which has over 3,000 drug treatment centers and a high rate of opioid use and relapse. Theo recognized the significance of these places carrying naloxone and decided to provide free training to them.


End Overdose was incorporated when Katie Krzywicki and Leah Schexnayder officially joined the team. Together, they worked established the framework for the organization's legal and website development.With their help, End Overdose earned a federal 501c3 status. End Overdose made connections with the LA County Substance Abuse Prevention Control, Harm Reduction Coalition, Remedy Alliance, Painted Brain, and other various government and community organizations. They registered with California's Narcan Distribution Project, receiving and distributing 120 kits at 15 different centers.

End Overdose was invited to give a naloxone training at the Echoplex in LA following Lil Peep's death. The event included Morgan Freed (owner and founder of emonite), Sirah, Natasha (Kreayshawn), and Brittney Scott, and became a monthly community meeting until the Covid-19 outbreak in 2020. End Overdose began work with the Los Angeles Nightlife Association, and built connections and trust various nightlife and unground party throwers such as restlessnites and the overpass.


End Overdose conducted trainings with West Hollywood City Counsel and formed partnerships with the Los Angeles mayor's office. Chris Poyorena came onboard to help run day to day operations, while Theo joined the Los Angeles City Fire Department. End Overdose began planning a pro bono media campaign worth $100,000 to train all Los Angeles residents to respond to overdoses. Unfortunately, the outbreak of Covid-19 led to the cancellation of the campaign and other plans.


End Overdose developed their first online training to conduct outreach during the pandemic, a time of increasing reports of fentanyl overdoses and lack of resources to prevent them.


End Overdose saw a huge uptake in online trainings due to increased social media traction. The California Narcan Distribution Project awarded End Overdose with 3600 doses of Narcan and End Overdose purchased 3000 doses of intramuscular naloxone for distribution. In October, End Overdose started providing formal trainings for larger scale nightlife events.


End Overdose released an updated version of their online training and partnered with artists and creatives such as Cami Petyn, Hvdes, and Cooper Noriega to expand their reach. They also launched their first college outreach chapter at UCLA and joined the mobilize recovery tour in September, distributing 10,000 doses of naloxone and 5000 fentanyl testing strips nationwide.

End Overdose partners with Insomniac Events, a leading EDM festival production company, in October 2022, to expand their reach into the music scene. Later that year, End Overdose collaborates with the National Association of City and County Health Officials and CDC Foundation on a project to provide trainings for middle and high schools across California.
