Have Your Say….your feedback is needed to help us communicate about opioid overdose prevention.
Fentanyl is an opioid that is much more toxic than most other opioids. Opioids include drugs like heroin, morphine, fentanyl, methadone and codeine. Fentanyl is usually prescribed in a patch form as a painkiller. It is around 50 to 100 times more toxic than morphine. This makes the risk of accidental overdose much higher.
There are also different Fentanyls being made illegally and sold on the streets. This illicit fentanyl is often made as a powder and mixed with other drugs (like heroin, cocaine or crack). It is also being pressed into pills and sold as things like ‘oxycodone’ (oxycontin, oxys, eighties) or other pills including speed and ecstasy/MDMA.
When fentanyl is mixed with other opioids, alcohol, benzodiazepines, or stimulants like cocaine, it increases the risk of accidental overdose.
Illicit fentanyl is much more toxic than other pharmaceutical opioids. There is no easy way to know if fentanyl is in your drugs. You can’t see it, smell it or taste it. Any drug can be cut (mixed) with fentanyl. Even a very small amount can cause an overdose.
When you are getting drugs from anywhere other than from a pharmacy or medical professional, like from a friend, ordering online, or a dealer, there is no way to be sure exactly what is in them or how toxic they may be.
It’s important to know that drugs other than fentanyl can also cause an overdose!
Carfentanil is an opioid that is used by veterinarians for very large animals like elephants. It is not for human use. It is approximately 100 times more toxic than fentanyl and 10,000 times more toxic than morphine. This means carfentanil can be deadly in extremely small amounts.
Carfentanil has been found here in Ontario. It is being cut in to other illicit drugs like heroin and counterfeit pills made to look like prescription opiods (including green pills stamped ‘CDN’ on one side and ‘80’ on the other). There is no easy way to know if carfentanil is in your drugs, you can’t see it, smell it or taste it. It is extremely toxic and a very small amount can cause an overdose.
What's the risk with counterfeit drugs?
Counterfeit pills can be manufactured to look almost identical to prescription opioids (i.e. Oxycontin, Percocet) and other medications. Obtaining drugs from a non-medical source such as a friend, ordering online, or a drug dealer is very risky and potentially life-threatening as there is no way to know what is actually in them or how toxic they may be. Drugs should only be purchased from a local pharmacy or a medical professional.

What is an overdose?
An overdose happens when a person uses more of a drug, or a combination of drugs, than the body can handle. As a result, the brain is not able to control basic life functions. The person may:
- Pass out,
- Stop breathing,
- Have a heart attack, or
- Experience seizures depending on what drugs they have used.
Learn the signs and symptoms of different types of drug overdoses below!
Anyone can overdose: first time users, people who have been using for a long time, people who use regularly, people who only use once and awhile, seniors, young people, overdose doesn’t discriminate.
- There is no exact formula for figuring out how much of a certain drug, or combination of drugs, will lead to an overdose. How strong a drug is (potency), how a drug is taken- whether swallowed, snorted of injected, how much of a drug, and how often a drug is used all are factors.
- Factors like weight, health, and tolerance for a drug at that particular time all play a role.
- Overdose risk is higher when you haven’t used in awhile (whether you took a break, or were in treatment, hospital, or jail).
Ottawa Overdose Statistics
In 2015, 48 Ottawa residents died from unintentional drug overdose:
- 29 of these, or almost 2 in 3 deaths were due to opioids
- Fentanyl was involved in 14 of these deaths, more than 1 in 4
Figure 1: Unintentional drug overdose deaths in Ottawa by type of drug involved, 2015
Data source: Office of the Chief Coroner for Ontario, extracted December 2, 2016. Analyzed by Epidemiology Team, Ottawa Public Health.
Age: These 48 overdose deaths were not distributed evenly across ages; some age groups were more impacted than others. One third of those who died, 15 people, were under 40 years old. See chart below.
Figure 2: Age distribution of Ottawa unintentional drug overdose deaths, 2015 (48 deaths total)
Data source: Office of the Chief Coroner for Ontario, extracted December 2, 2016. Analyzed by Epidemiology Team, Ottawa Public Health. (Data table below)
The rate of drug overdose increased 32% in Ottawa between 2014 and 2015 and only 6% in the rest of Ontario.
The increase in unintentional overdose deaths in Ottawa and in the rest of Ontario has been due to increased unintentional opioid overdose deaths, and since 2014, fentanyl has been involved in the largest proportion of drug overdose deaths in Ottawa. For more information see “Drug-related death in Ottawa, 2000-2015”.
If you are going to use:
Don’t Use Alone
- If you overdose when you are alone there will be no one there to help you.
- When using with someone else, don’t use at the same time. Be sure your friend is willing to call for help, and make a plan for what to do if an overdose happens.
- If you do use alone, tell someone before you use. Leave the door unlocked and have someone come check on you.
Don’t Mix Drugs
- Don’t mix drugs with other drugs or alcohol.
- Mixing with other drugs puts you at higher risk of overdose.
- If you are going to mix, use one drug at a time or use less of each drug.
- The quality of street drugs is unpredictable. Fentanyl is being cut (mixed) into both opioid and non opioid drugs:
- Made as a powder and mixed into cocaine, heroin, and crack.
- Made as pills and being sold as ‘oxycodone’ (eighties, oxys) or other pills including ecstasy/MDMA.
- You may not be able to taste, smell or see it. Even very small amounts can cause an overdose.
- Start using in small amounts and do “testers” (or test doses) to check the strength of what you are using.
- Naloxone is a medication that can temporarily reverse an opioid overdose.
- Naloxone is available free to people who use drugs and their family and friends!
- Learn more about Naloxone and where to get a kit.
Know your tolerance
- Tolerance is the body’s ability to ‘handle’ the effects of the drug being used. Tolerance to a drug develops over time.
- Drug tolerance will decrease when somebody has taken a break from using – whether intentionally or unintentionally (like while in treatment, hospital or jail).
- Your tolerance will also change depending on:
- Lower immune system (from hepatitis for example),
- Lack of sleep,
- Other drugs/medications being used, and
- General health.
- Use less drugs when your tolerance may be lower.
- Your risk of overdose increases if you are a new user or haven’t used in 3+ days!
- Drugs can be tampered with at any point. People buying or selling drugs may not be aware if it has been cut with anything before they sell it to you.

Naloxone is a medication that can temporarily reverse the effects of an opioid overdose. Opioids include drugs like heroin, morphine, fentanyl, methadone and codeine.
How does Naloxone work?
In an opioid overdose a person’s breathing slows down or stops. Naloxone blocks the effect of opioids on the brain. It temporarily reverses these effects on a person’s breathing. Giving naloxone can prevent death or brain damage from lack of oxygen.
Naloxone will only work on opioid-related overdoses. It is important to remember that a lot of other drugs are being cut with fentanyl. If the person has used any drugs and is showing signs of an opioid overdose call 911 and give naloxone.
How long does Naloxone take to work?
Naloxone usually starts working in 1 to 5 minutes. Repeated doses may needed if the person is still showing signs of overdose.
The effects of naloxone only last for 30 to 60 minutes. If the opioid is still in the body after the naloxone wears off, the overdose can return. This is why it is so important to call 911 in every overdose situation!
Learn more about Naloxone from the following University of Waterloo video:
Being able to recognize the signs of an overdose quickly and having a naloxone kit can save a life. Naloxone can buy time while paramedics are en route. Take-home naloxone kits do not replace the need for emergency care or minimize the importance of calling 911.
You can get a take-home naloxone kit for free from pharmacies and other agencies in Ottawa. When you get your kit you will also receive training on overdose prevention, recognizing an overdose and how to respond. Below is a list of places where you can get a free Naloxone kit in Ottawa:

5 Steps to Save a Life
- Shake & shout: Shake the person’s shoulders and shout their name
- Call 9-1-1: If the person is not responding
- Naloxone: Inject 1 ampoule (1ml) of naloxone into the arm or leg muscle
- Compressions or CPR and/or rescue breathing as trained
- Is it working? If there is no change after 3-5 minutes give the next dose of naloxone and continue with compressions/recue breathing/CPR until ambulance arrives
If you have to leave the person at any time put them in the recovery position. The recovery position helps keep a person’s airway open so they can breathe and can prevent them from choking on vomit or spit.
- Responder extending victims closest arm above the victims head
- Responder positions other arm across the victims chest and bends furthest leg at the knee. Victim is rolled towards responder and placed on side
- Victim laying on side with head stabilized on extended arm. Knee is bent and stabilized
It is important to stay with a person after giving them naloxone:
- The person may be confused and frightened when they wake up. You will need to tell them what happened.
- A lot of opioids can last longer in the body than naloxone, so an overdose could return. It is important to make sure that the person knows not to take any more drugs!
- It is important to tell paramedics everything you know about the situation so they can provide the best care.
- Naloxone may cause people who have used opioids to go into withdrawal. This may make the person want to use again. Using more will increase the risk of overdose as the naloxone wears off.
- This can be very uncomfortable for the person but is not life threatening. Withdrawal symptoms may include:
- Muscle aches,

Used Medication Disposal at Pharmacies
Pharmacies play a fundamental role in raising awareness about the importance of properly disposing of unused or expired medications by providing a drop-off locations for such medications as over-the-counter, prescription and natural health products through Health Products Stewardship Associations’ (HPSA) Medications Return Program (OMRP), and for sharps materials and devices through its Sharps Collection Program (OSCP).
- Ottawa Public Health (OPH) is working in partnership with the Health Products Stewardship Association (HPSA) to raise public awareness of the importance of safe disposal of unused or expired medications. Success depends on participating pharmacies being informed about the procedures, guidelines and regulations of the Ontario Medications Return program (OMRP), and actively offering the collection and management of unused or expired medications returned by the public.
- You can call the HPSA to register your location at 613-723-7282 or send an email to firstname.lastname@example.org. The OMRP covers the costs associated with the responsible disposal of health products returned by the public. There is no cost to you.
- If you would like to receive FREE copies of the Take it Back! public rack cards, pictured below, you may use the order form, or call or email the Health Products Stewardship Association to receive copies. They will be happy to send you English and /or French copies, free of charge, to your pharmacy location(s).
