A small dose of fentanyl can be fatal depending on how tolerant someone is and their body size. Coroners’ offices and state crime laboratories do not test for fentanyl unless given a specific reason to do so. Older people are more likely than younger individuals to experience adverse effects, especially the respiratory depressant effects of fentanyl. Healthcare professionals will typically monitor people in this age group. Opioids are a class of drugs that include both prescription medicines such as morphine and illegal drugs like heroin.

Deaths Involving Illegally Made Fentanyl Are Rising
Addiction Resource aims to provide only the most current, accurate information in regards to addiction and addiction treatment, which means we only reference the most credible sources available. It is sadly not uncommon now to find heroin, cocaine, methamphetamine, or MDMA laced with fentanyl on the street. It’s crucial to remember that there is no way to verify the actual content or purity of fentanyl bought illicitly. Even a small amount of fentanyl can be deadly, and using it, particularly when obtained illegally, carries extreme risks. To get extremely potent opioids, users turn to the dark web—and sometimes, Google. Watch a video on How to use fentanyl test strips from Prevent Overdose-Rhode Island.
China Agreement Alone Won’t Solve Fentan
Over 300 Americans die every day from overdoses related to synthetic opioids like fentanyl. Using fentanyl regularly can lead to an opioid use disorder (OUD). OUDs are chronic but treatable medical conditions that involve changes in our brains, which makes stopping very difficult without support. Effective medications that address cravings and withdrawal symptoms, as well as behavioral treatments, can help people with OUDs. From April 2024 to March 2025, the CDC reported 43,000 synthetic opioid deaths, most of which are from fentanyl, down from nearly 70,000 in the previous similar period.
If A Person Has Naloxone, Is Fentanyl Safe To Use?
Avoid drinking alcohol for several hours after you take fentanyl. Your doctor might prescribe fentanyl if you have severe pain due to cancer, nerve damage, serious injury, or major surgery. Some people claim they can tell they are taking fentanyl, rather than heroin, due to its pale color (which ranges from bright white to off-white) and sweet taste.
For the past three years, he’s been buying fentanyl and its analogues, like carfentanil, online. When he receives it, he measures it out in water, which he says makes for greater accuracy. Now, for that amount, he can get enough fentanyl to last more than three weeks. The drug user in Texas said he first began using opioids when a doctor prescribed him hydrocodone for a bad cough he had as a teenager. He progressed to prescription painkillers, and then, when they became too expensive, to heroin.
Adverse Effects

To prevent accidental fentanyl overdoses, you can use fentanyl test strips to ensure other drugs don’t contain the opioid. You can get them free through some outreach programs, such as needle exchanges or overdose prevention programs. See the impact of fentanyl and other synthetic opioids on drug overdose deaths. Fentanyl, regardless of its form, is extremely potent and dangerous. Just two milligrams of fentanyl can be fatal for the average person. When fentanyl is mixed into other drugs, it cannot be seen, smelled, or tasted, and it’s nearly impossible to distinguish counterfeit pills containing fentanyl from legitimate ones.
One of the major problems with fentanyl sold on the street is that there is no way to know how much fentanyl something contains, and it is one of the easiest opioids to overdose on. Fentanyl is a naturally occurring substance in the human body known for its calming and euphoric effects. It’s commonly used in clinical settings and by individuals seeking relaxation or to improve sleep quality.
Treating Fentanyl Addiction
- Fentanyl is a potent synthetic opioid, which, similar to morphine, produces analgesia but to a greater extent.
- The biggest risk factor is that people are often exposed unintentionally and don’t know to take the proper precautions to use this drug safely.
- Prescription fentanyl is available under such names as Actiq®, Duragesic®, and Sublimaze® in the form of tablets, an injectable liquid, lozenges and patches.
- That is, in combination with certain neuroleptic medications as part of therapeutic neuroleptanalgesia.
- An overdose happens when a drug produces serious adverse effects and life-threatening symptoms.
The antidote naloxone (Narcan) can reverse the effects of a fentanyl overdose if given in time. To put it in perspective, it’s 50 to 100 times more potent than morphine. According to the CDC, overdoses involving synthetic opioids increased by 72.2% from 2014 to 2015.

Although fentanyl patches are a legal form of the drug doctors sometimes prescribe for pain, they are easily abused. People may take the gel out of the patch and either put it in their mouth or inject it. When it’s in powdered form, it looks a lot like other powdered drugs such as cocaine. Powdered fentanyl can also be pressed into pills that look like prescription pills such as Percocet or Xanax. People sell illegal fentanyl as a powder, dropped onto blotter paper, put in eye droppers and nasal sprays, or as pills that look like other prescription opioids. If the patient has used a monoamine oxidase inhibitor in the previous 14 days, fentanyl is contraindicated.

Naloxone acts quickly to reverse the effects of an opioid overdose, but opioids last much longer than naloxone. Additional doses of naloxone are therefore sometimes necessary. People who receive naloxone still require an emergency medical evaluation, as overdose symptoms can return.
Calling the number is free and confidential, but treatment services may involve costs depending on your insurance coverage and the level of care required. You are under no obligation to engage in care with Treatment X. If you or a loved one is battling fentanyl addiction, an opioid detox program will be the first step in your journey to recovery.

Detailed Report

The effects of fentanyl (and all opioids) can be blocked and reversed with the use of Narcan. Anyone can purchase Narcan over the counter, and there are places that give it away for free (see below). Although most often used to cut powdered opiates, fentanyl is also used to cut pills and drugs like cocaine, ketamine, methamphetamines (like ADHD pills), and benzodiazepines (like Xanax). Fentanyl is a synthetic opioid that is up to 50X stronger than heroin and 100X stronger than morphine.
Fentanyl comes as two different transmucosal products and several other types of products. The medication in each product is absorbed differently by the body, so one product cannot be substituted for any other fentanyl product. If you are switching from one product to another, your doctor will prescribe a dose that is best for you. Prescription fentanyl is available under such names as Actiq®, Duragesic®, and Sublimaze® in the form of tablets, an injectable liquid, lozenges and patches. There is no set amount that is considered lethal because how the drug affects you depends on several factors such as your body size and tolerance.
