Kingston, a university city in southeastern Ontario with approximately 135,000 residents, has experienced a dramatic escalation in opioid-related deaths over the past decade. The Kingston, Frontenac, Lennox and Addington (KFL&A) health region recorded fewer than 12 opioid deaths per year before 2016, but this number surged to 42 deaths in 2020—a more than 250% increase. Between May 2017 and June 2021, a total of 135 people died of opioid overdoses in the region, according to peer-reviewed research published in the Canadian Journal of Public Health.
The demographics of Kingston's overdose victims challenge common stereotypes: the average age was 42 years, and only 5.9% had no stable housing—meaning the vast majority (94.1%) were housed individuals living seemingly normal lives. Most decedents (79.3%) died in private homes, and 69.3% were alone at the time of overdose. Males accounted for 71.1% of deaths. Fentanyl and carfentanil—ultra-potent synthetic opioids—were present in 76.3% of deaths, while 51.9% of decedents also used methamphetamines, indicating widespread polysubstance use. Common co-occurring conditions included depression (35.6%), chronic pain (26.7%), and anxiety disorders (18.5%).
Kingston offers a range of addiction treatment services including medical detox, residential rehab, outpatient programs, and medication-assisted treatment. The region's four correctional facilities add complexity to the crisis: 23.7% of overdose victims had a history of incarceration, with some dying shortly after release when tolerance is lowest and overdose risk highest. Local public health officials emphasize the need for harm reduction services including naloxone distribution, safer supply programs, and interventions specifically targeting people who use substances alone—the single biggest risk factor for fatal overdose in the KFL&A region.

Kingston's opioid crisis defies stereotypes. Unlike the image of street-involved individuals experiencing homelessness, the data reveals that 94.1% of people who died of opioid overdoses in the KFL&A region had stable housing. They were parents, employees, students, and community members living seemingly normal lives. The average age of 42 years indicates this crisis primarily affects middle-aged adults—people with established lives, families, and responsibilities—not just youth or elderly populations.
The location of deaths tells a sobering story: 79.3% of overdoses occurred in private homes, where help was often unavailable or delayed. Most critically, 69.3% of people who died were alone at the time of overdose. Using substances alone is the single biggest preventable risk factor for fatal overdose, because there is no one present to call 911, administer naloxone, or provide CPR. When overdose strikes in private, minutes matter—and isolation turns survivable overdoses into deaths.
Research from Kingston indicates that people use substances alone for multiple reasons: hiding use from family or friends due to stigma, fear of criminalization and police involvement, unwillingness to share limited drug supplies with others, or simply believing they're experienced enough to use safely without supervision. The COVID-19 pandemic did not significantly change the rate of solitary use in Kingston, suggesting this is a long-standing pattern driven by deeper social and structural factors rather than temporary public health restrictions.
The demographics also reveal important vulnerabilities: 35.6% of decedents had a prior diagnosis of depression, 18.5% had anxiety disorders, and 26.7% had chronic pain diagnoses documented in their medical records. These co-occurring conditions—mental health disorders and untreated pain—are well-established risk factors for substance use and overdose. Addressing Kingston's crisis requires integrated treatment addressing both addiction and underlying mental health or pain management needs simultaneously.
Fentanyl and carfentanil—synthetic opioids 50-100 times and 10,000 times stronger than morphine, respectively—were present in 76.3% of opioid deaths in the KFL&A region between 2017 and 2021. These ultra-potent substances have contaminated the unregulated drug supply, often mixed into street heroin, counterfeit pills, cocaine, or methamphetamine without users' knowledge. The unpredictability of the supply means users cannot know the strength or contents of what they're consuming, dramatically increasing overdose risk.
Polysubstance use is increasingly common and deadly: 51.9% of people who died in Kingston also used methamphetamines, with the highest co-use rates occurring in 2019-2020. Nearly 21% had cocaine in their blood at time of death. The combination of opioids (which depress breathing) and stimulants (which increase heart rate and blood pressure) creates unpredictable and dangerous drug interactions. Stimulants may also mask opioid effects, leading users to consume more opioids than intended, triggering delayed overdoses as stimulant effects wear off.
Benzodiazepines were present in fewer than 15% of deaths, but when combined with opioids, they significantly increase respiratory depression and overdose risk. Prescription opioids like hydromorphone and oxycodone were also present in fewer than 15% of cases, indicating that most overdose deaths involve street drugs rather than prescribed medications. This suggests the crisis is driven by a toxic, unpredictable unregulated supply rather than prescription opioid misuse as was common in earlier phases of the epidemic.
Few people had naloxone, buprenorphine (Suboxone), or methadone in their blood at time of death—less than 13% were accessing opioid substitution therapy (OST). This could indicate that people who use OST do not die of overdoses (an optimistic interpretation), or that there are significant barriers preventing people who use opioids from accessing evidence-based treatment in the KFL&A region. Given that OST reduces overdose deaths by 40-60% according to SAMHSA research, expanding access to medication-assisted treatment must be a priority for Kingston and surrounding communities.
Kingston hosts four correctional facilities and over 2,000 prisoners who use Kingston health services, making justice-involved populations a critical consideration in the region's overdose crisis. Research on KFL&A overdose deaths found that 23.7% of decedents had a prior history of incarceration, and eight people (5.9%) died in correctional facilities themselves. Of those with incarceration history, 15.6% were released in the four weeks before death—a period of exceptionally high overdose risk.
The post-release period is deadly because tolerance to opioids drops dramatically during incarceration due to forced abstinence or reduced access. When individuals return to street drug use after release, they often use the same dose they consumed before incarceration—not realizing their body can no longer tolerate it. Combined with the stress of reentry, lack of stable housing or employment, severed social connections, and limited access to addiction treatment or medication-assisted therapy, the two weeks following release are a perfect storm for fatal overdose.
Research consistently shows the substance-related mortality rate for prisoners and ex-prisoners is 32 times higher than in the age- and sex-matched general population. High-quality studies have identified effective strategies for addressing this vulnerable population: robust opioid substitution therapy programs inside correctional facilities, take-home naloxone programs upon release, pre-release linkage to community addiction services, and immediate connection to housing and social supports. These evidence-based approaches can dramatically reduce overdose deaths among justice-involved populations.
Implementing these strategies in Kingston's correctional facilities could save lives. However, institutional resistance, punitive drug policies, and insufficient funding for in-custody treatment programs create barriers. Public health officials emphasize that treating addiction as a medical condition rather than a moral failing—even (and especially) within correctional settings—is essential to preventing overdose deaths among one of Kingston's most vulnerable populations.
Kingston provides addiction treatment services across the continuum of care, though capacity falls short of demand. Medical detox programs offer 24/7 supervised withdrawal management for alcohol, opioids, benzodiazepines, and other substances. Medical supervision is essential for alcohol and benzodiazepine withdrawal due to life-threatening seizure risk, and greatly improves comfort and completion rates for opioid withdrawal, which causes severe flu-like symptoms but is not typically fatal.
Residential inpatient rehab centers provide 30-90 day structured programs combining medical care, individual therapy, group counseling, and relapse prevention education. Evidence-based approaches such as Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), and trauma-informed care are commonly used. Given that 35.6% of Kingston overdose victims had depression and 18.5% had anxiety disorders, integrated dual diagnosis treatment addressing both addiction and mental health simultaneously is critical and produces significantly better outcomes than treating each separately.
Outpatient programs—including Intensive Outpatient (IOP) and Partial Hospitalization Programs (PHP)—allow residents to live at home while attending structured therapy sessions 3-5 times per week. These programs work well for individuals with stable housing (which applies to 94% of Kingston's population at risk based on overdose data) and strong support networks. Specialized programs for youth, women, Indigenous communities, and university students reflect Kingston's diverse population needs.
Medication-Assisted Treatment (MAT) for opioid use disorder is available through addiction medicine clinics and healthcare providers in Kingston. Medications like methadone, buprenorphine (Suboxone), and naltrexone reduce cravings, block opioid effects, and prevent withdrawal. Research shows MAT reduces overdose deaths by 40-60% according to SAMHSA. However, only 13% of Kingston overdose victims had OST in their blood at time of death, suggesting either that MAT is highly effective (people using it don't die) or that access barriers prevent more people from benefiting from this life-saving treatment.
Harm reduction services are critical given that 69% of Kingston overdose deaths occur while using alone. Naloxone distribution programs train community members to recognize overdose symptoms and administer the life-saving medication. Encouraging people who use drugs to never use alone is essential—tools like the National Overdose Response Service (NORS) hotline or Lifeguard Digital Health app provide check-in services that automatically dispatch EMS if users become unresponsive. Research from Kingston emphasizes that addressing stigma, fear of criminalization, and social isolation are necessary to reduce solitary use and prevent deaths.
If you or a loved one in Kingston is struggling with addiction, help is available 24/7. Call the province-wide Drug and Alcohol Helpline at 1-800-565-8603 (free, confidential) to speak with a counselor who can assess your needs, explain treatment options, verify insurance coverage, and provide referrals to Kingston-area facilities and services.
KFL&A Public Health provides harm reduction services, naloxone kits, overdose response training, and connections to treatment. Visit kflaph.ca for local resources. Connex Ontario (1-866-531-2600) offers information and referrals for mental health and addiction services across the province.
Emergency situations: If someone is experiencing overdose symptoms—unresponsiveness, slow or stopped breathing, blue lips/nails, choking sounds—call 911 immediately and administer naloxone if available. Ontario's Good Samaritan Drug Overdose Act provides legal protection for individuals who call 911 during an overdose. You will not be charged for simple drug possession when seeking emergency medical help.
If you use alone: Call the National Overdose Response Service (NORS) at 1-888-688-NORS (6677) before using. A trained responder stays on the line and will call EMS if you become unresponsive. Download the Lifeguard Digital Health app for automated check-ins. Never use alone if you can avoid it—69% of Kingston overdose deaths occurred when people were alone, and having someone present to call for help or administer naloxone is the difference between life and death.
Treatment works. Research consistently shows that individuals who complete addiction treatment programs have significantly lower rates of substance use, improved mental and physical health, better employment outcomes, and higher quality of life. Relapse is common—addiction is a chronic condition requiring ongoing management—but each treatment attempt builds skills, coping mechanisms, and hope.
Don't wait for rock bottom. Early intervention saves lives. Whether you're considering outpatient counseling, residential treatment, medication-assisted therapy, or harm reduction services, taking the first step today could save your life. Kingston's crisis affects housed, middle-aged adults living seemingly normal lives—if that's you, you're not alone. Recovery is possible.
