Heroin and Fentanyl in Maryland: Why Baltimore Became Ground Zero

Baltimore’s relationship with heroin is old, deep, and devastating. While the national conversation about opioids in the 2010s focused largely on suburban prescription pill abuse, Baltimore was already decades into a heroin crisis that the rest of America largely did not see. By the time fentanyl arrived, it landed in a city where between 5 and 10 percent of the adult population already used heroin — a figure that Johns Hopkins Bloomberg School of Public Health researchers documented and that would make Baltimore’s overdose rate among the highest of any major American city.

Understanding how this happened — the history, the structural causes, the current reality of fentanyl contamination — is essential for anyone trying to grasp what Maryland faces today and how to help.

How Heroin Took Root in Baltimore

Heroin’s presence in Baltimore cannot be separated from the city’s economic and social history. During the post-World War II era, Baltimore’s industrial economy was robust — steel, manufacturing, and the port provided stable working-class employment. As those industries declined through the 1960s, 1970s, and 1980s, entire communities lost their economic foundation.

Disinvestment accelerated in predominantly Black neighborhoods, many of which were already shaped by decades of redlining, school segregation, and discriminatory housing policy. The War on Drugs intensified mass incarceration, destroying family structures and economic prospects without meaningfully reducing drug use. By the 1990s, Baltimore had neighborhoods where multi-generational heroin use was a grim norm — where grandparents, parents, and children were all using.

The Centers for Disease Control and Prevention (CDC) and the National Institute on Drug Abuse (NIDA) have documented extensively that social determinants — poverty, trauma, housing instability, unemployment, lack of educational opportunity — powerfully predict substance use disorder. Baltimore’s heroin crisis is inseparable from those determinants.

The Scale of Baltimore’s Heroin Problem

During the peak years of the early 2000s, researchers at the Baltimore Substance Abuse Systems program estimated that Baltimore had approximately 60,000 people who used heroin regularly — in a city of approximately 640,000. That is roughly 1 in 10 adults. No major American city had a higher per-capita heroin use rate.

These numbers were not hidden. They were studied by Hopkins researchers, documented by Maryland health officials, reported by journalists, and largely ignored by federal policymakers who were more comfortable discussing drug use in suburban or rural communities.

The Maryland Department of Health’s Behavioral Health Administration (BHA) has long tracked these statistics. SAMHSA’s annual survey data consistently places Maryland among the states with the highest rates of opioid use disorder.

The Arrival of Fentanyl: From Bad to Catastrophic

Beginning around 2013 and accelerating sharply after 2016, illicitly manufactured fentanyl began appearing in Maryland’s heroin supply. At first it was mixed in — added to increase potency. Then, as supply chains shifted, fentanyl increasingly displaced heroin entirely. What was sold as heroin in Baltimore and throughout Maryland became primarily or entirely fentanyl.

This matters enormously for overdose risk:

• Fentanyl is 50–100 times more potent than morphine by weight
• Illicitly manufactured fentanyl is produced with no quality control, meaning the potency of any given dose is unpredictable
• A dose that does not cause overdose one day may be lethal the next if the batch has higher fentanyl concentration
• Fentanyl is increasingly found in cocaine, methamphetamine, and counterfeit pills — meaning people who do not intend to use opioids are unknowingly exposed

Maryland’s overdose death toll reflects this shift dramatically. The Maryland Department of Health reports that fentanyl is now detected in the overwhelming majority of opioid overdose deaths in the state. In Baltimore City, overdose death rates have continued to climb even as they plateau in some other states — reflecting both the depth of the heroin use disorder infrastructure and the particular lethality of fentanyl.

SAMHSA and the CDC have both noted that overdose deaths among Black Americans have increased disproportionately during the fentanyl era, partly because fentanyl contamination of stimulants like cocaine has exposed communities that historically used cocaine rather than heroin to opioid overdose risk.

Carfentanil and Next-Generation Opioids

Fentanyl itself has been joined in the drug supply by analogs — chemically related compounds that may be even more potent. Carfentanil, used as a tranquilizer for large animals, is approximately 10,000 times more potent than morphine. Even microgram quantities can cause overdose. Maryland’s drug testing infrastructure has detected carfentanil and multiple fentanyl analogs in seized drug samples and in postmortem toxicology from overdose deaths.

The NIDA and the DEA have documented the increasing complexity of the synthetic opioid supply and its implications for harm reduction and treatment.

The Role of Naloxone in Saving Lives

Naloxone (brand name Narcan) is an opioid antagonist that can reverse an opioid overdose within minutes when administered as a nasal spray or injection. It is safe, effective, and — in the current fentanyl era — essential.

Maryland has made naloxone available without a prescription at pharmacies statewide and has funded extensive distribution through harm reduction programs, first responders, and community organizations. The Maryland Department of Health reports that naloxone administration by bystanders, first responders, and community members has prevented thousands of deaths.

Anyone in Maryland who is at risk of opioid overdose, or who knows someone who is, should have naloxone available. It is available at pharmacies without a prescription. Training on how to use it is available through local health departments, harm reduction programs, and online resources.

Treatment for Opioid Use Disorder: What Works

The most effective treatments for opioid use disorder — validated by SAMHSA, NIDA, and the CDC — are medications:

Buprenorphine: A partial opioid agonist that reduces cravings and withdrawal symptoms without producing significant euphoria. Available through office-based settings and telehealth providers throughout Maryland. Highly effective at keeping people in treatment and alive.

Methadone: A full opioid agonist dispensed through federally licensed Opioid Treatment Programs (OTPs). Baltimore has multiple OTPs, and the state has OTPs in many regional centers. Decades of research support methadone’s effectiveness for severe opioid use disorder.

Naltrexone: Blocks opioid effects entirely. Available as a monthly injection (Vivitrol). Requires complete opioid detox before initiation.

These medications are not “substitutes” for opioids in a pejorative sense — they are evidence-based medical treatments that save lives. The stigma that labels people on MAT as “not really in recovery” is not supported by science. SAMHSA explicitly affirms that people on medication-assisted treatment are in recovery.

Baltimore-Specific Harm Reduction Programs

Harm reduction — meeting people where they are without judgment, and taking steps to reduce the risk of death while they are using — is an essential part of addressing the fentanyl crisis. Baltimore has several active harm reduction programs:

Baltimore City Health Department: Operates needle/syringe service programs, naloxone distribution, and fentanyl test strip availability.

Baltimore Harm Reduction Coalition: Community-based harm reduction services.

SPARC (Supportive Programs for Addiction Recovery and Change): Peer-based harm reduction and recovery support in Baltimore.

MATCH (Mobile Addiction Treatment with Community Help): Mobile services connecting people who use drugs with treatment and support.

These programs save lives and serve as entry points into treatment for many people who are not yet ready to stop using.

Warning Signs and How to Get Help

If you or someone you love uses opioids and shows any of the following, call for help today:

• Increasing use, or inability to stop despite wanting to
• Withdrawal symptoms when not using (sweating, nausea, muscle aches, anxiety)
• Tolerance — needing more to get the same effect
• Using in dangerous situations, or being unable to fulfill major responsibilities
• Legal, financial, or relationship problems related to use

Treatment is available, it works, and recovery is possible — even from severe, long-term opioid use disorder.
