Opioids

Opioids are substances that can be prescribed to treat pain, severe cough and diarrhea. Some people use opioids because of their euphoric effect. Examples of opioids include fentanyl, heroin, morphine, oxycodone, codeine and hydromorphone. Opioids can be addictive, and if taken at high doses, can cause coma or death. Special types of opioids, including methadone and buprenorphine/naloxone, are used in opioid treatment programs.

What is fentanyl?

Fentanyl is an opioid that is approximately 100 times more potent than morphine and 40 times more potent than heroin. Fentanyl can be prescribed by a physician or obtained through an unregulated, toxic supply. Fentanyl and its analogues are trafficked and sold in many different forms including patch, powder, pill and liquid. “Street” drugs can be contaminated with fentanyl making them more potent and increasing the risk of overdose. Fentanyl use and overdose has been on the rise in Ontario over the last several years.

For more information on opioids, visit Health Canada’s webpage.

Overdose is preventable and so are overdose-related deaths. It’s important to understand the risks and signs as well as the steps you can take to help prevent an overdose in the first place.

What is an overdose?

An overdose occurs when a person uses a drug or combination of drugs that the body cannot handle. The current overdose crisis is largely a result of poisoning from an unpredictable and unregulated supply of drugs. Many overdose deaths are accidental or unintentional.

What are the signs and symptoms of an opioid overdose?

Recognize the signs and symptoms of an overdose, which include:

• Difficulty walking, talking and staying awake
• Blue or purple lips or nails
• Very small pupils (black, circular part of eyes)
• Cold and clammy skin
• Dizziness and confusion
• Extreme drowsiness
• Choking, gurgling or snoring sounds
• Slow, weak or no breathing
• Inability to wake up, even when shaken or shouted at

Call 911 immediately to get help. See the ‘Responding to an opioid overdose’ section below for information about the Good Samaritan Drug Overdose Act.

For more information about opioid overdose, visit Health Canada or Ontario.ca/opioids

Who is at risk of an opioid overdose?

You, your friend or family member is at risk of an opioid overdose if you/they:

• Are taking prescription opioids that were not prescribed to you/them
• Are buying opioids from the street and don’t know how strong they are
• Have bought street drugs contaminated with opioids
• Have overdosed on opioids before
• Are mixing opioids with other downers like alcohol or benzodiazepines (e.g., Valium, Xanax)
• Have stopped using opioids for a while (which lowers tolerance) and start using again
• Are using opioids by yourself
• Are using opioids in a new or different way (e.g., injecting, snorting or crushing)
• Are taking a higher dose than normal
• Are living with or have a history of mental illness (e.g., depression, psychosis)
• Are living with health issues (e.g., liver, kidney, heart, breathing issues)
• Lack sleep (impaired judgment) or food
• Are in a hurry to use
• Have a new dealer or are using unknown substances

How to reduce the risk of an opioid overdose

• Try not to use alone. Make sure someone is around to check on you in case you overdose. If you are alone while using substances, these services below will support you over the phone or call 911, if needed:
  • National Overdose Response Service (1-888-688-6677)
• Do not mix drugs or take drugs with alcohol. The risk of overdose increases if opioids are mixed with alcohol, sleeping or anxiety pills, other opioids or other prescription medications
• Try a small amount first. If switching to a stronger opioid, use less and do a test dose
• Start low and go slow. If using opioids after cutting down, or not using for a while, use slowly; don't feel pressured to rush; do a tester dose first to see how you feel
• Check your drug before using. Ask others what they are experiencing with the same batch or if possible, check your drug at a drug checking service in Toronto
• Have and be trained to use naloxone. See the ‘Naloxone and harm reduction supplies’ section below for more information on naloxone
• Create an overdose plan. Talk with your friends and family about overdose and create a realistic plan you can use in the event of an overdose. Make sure they know where you keep your naloxone or ask that they keep their own kit on hand

When you think someone has overdosed, follow the steps below to help save a life.

Always call 911 if someone is overdosing on opioids, whether or not naloxone is used. Naloxone is a non-opioid medication that counteracts the effects of opioid overdose. It comes in a nasal or injectable form.

The Good Samaritan Drug Overdose Act is a federal law that provides legal protection for persons who call 911 to seek medical or law enforcement assistance in a drug overdose situation, whether the person is calling for oneself or another person who is overdosing. The Act provides protections for persons from being criminally charged for simple possession or violation of one’s bail or probation conditions as a result of using drugs, for example. It does NOT provide persons with protection from being charged with more serious offences such as drug trafficking or weapons offences.

Nasal and/or injectable naloxone kits and refills are available without a prescription, at no cost for people who are at risk of opioid overdose and for their concerned friends and family members. Harm reduction supplies include safer injection, inhalation and snorting supplies as approved by the Ontario Harm Reduction Distribution Program. Visit york.ca/harmreduction for more information.

If you or someone you know had a bad reaction to street drugs, including if you experienced an overdose, you can make an anonymous report about it to York Region Public Health at york.ca/reportbaddrugs

You can make one report at a time to tell people about:

• An overdose caused by street drugs, including opioids such as fentanyl, morphine etc.
• An unexpected or bad reaction to drugs 

You do not have to answer all the questions, but please include as much detail as you can. Public Health may use the information to inform the public about risks or trends in the community.

The 2024 Opioid Action Plan builds off the work of the original document launched in 2019, and has outlined 20 different actions, organized into six areas of focus:

• Stigma reduction
• Prevention
• Harm reduction
• Treatment
• First response and community safety
• Data and Early Warning

A community approach is essential. We need to work together to address the challenges faced by our community and people who use drugs.

Whether someone you love or know uses substances or not, you can help reduce the stigma experienced by people who use substances such as opioids. Stigma is negative attitudes, beliefs or behaviours about or towards a group of people because of their situation in life. It includes discrimination, prejudice, judgment and stereotypes, which can isolate people who use drugs and prevent them from talking about their substance use and reaching out for support.

What is stigma?

Stigma is prejudice and discrimination toward people who use substances. Stigma isolates people and can lead to feelings of guilt, shame, hopelessness and greater harm to the individual and community. People may experience additional stigma and discrimination because of their age, disability, religion, gender identity, sexual orientation, race, Indigenous identity or housing insecurity. 
Examples and effects of stigma include:

• negative attitudes or behaviours towards people who use drugs or towards their friends and family members
• negative labels and images in everyday conversation and in the media
• policies in health and social services that increase stigma, such as not providing services until drug use is better managed
• when healthcare providers or first responders do not take people affected by drug use seriously
• using substances alone which increases the risk of overdose/poisoning
• feelings of shame and hopelessness, isolation and using substances to cope

Stigma can result in exclusion from accessing and maintaining work, a safe place to live and other health and social services. Learn more about the three types of stigma: structural stigma, social stigma and self stigma.

Actions to reduce stigma

Together we can reduce stigma, increase inclusion, empathy and connections by:

• Learn about opioids and how to use naloxone to save a life 
• See people for who they are, not for their drug use
• Listen with compassion and respect so people feel heard and understood
• Talk about stigma and share experiences that impact ourselves or others
• Organize or attend stigma reduction education or community events
• Include people with lived/living experience in stigma reduction work
• Include peer support in health and social services involving substance use
• Review policies and programs to promote equity
• Be inclusive and welcoming to people who use drugs
• Change how we talk about substance use. Use people first language.
  • Use “substance use” instead of “drug abuse”
  • Use “a person who uses substances” instead of “junkie”
  • Use “people living with a substance use disorder” instead of “addict”
