Two milligrams of fentanyl can kill someone, based on their body size, tolerance, and how much they have used in the past. DEA tests have found fake pills with anywhere from 0.02 to 5.1 milligrams of fentanyl per tablet, which is more than twice the amount that can kill. Many factors are involved when conducting a test and examining reactions, and The Bunk Police does not assume responsibility for the interpretation of results. Reactions of individual samples can vary depending on lighting differences and the specific mixtures of substances being tested. Bunk Police kits are intended for identifying unknown substances for harm reduction purposes only. When you use an illegal drug, there’s no guarantee that it contains what the dealer or person who gave it to you says it does.
If A Person Has Naloxone, Is Fentanyl Safe To Use?

Sometimes people freeze fentanyl patches and cut them into smaller portions. Then they put these small pieces in their cheeks or under their tongue. Your doctor might prescribe fentanyl if you have severe pain due to cancer, nerve damage, serious injury, or major surgery. The Stop Overdose website educates drug users on fentanyl, naloxone, polysubstance use, and dealing with stigma.

In An Emergency? Need Treatment?
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. The use of fentanyl citrate injection with CYP3A4 inducers or stopping the CYP3A4 inhibitor will require close and repetitive monitoring of the patient. Also, consider augmenting the dose of fentanyl as needed. Drugs may contain deadly levels of fentanyl, and you wouldn’t be able to see it, taste it, or smell it.
- This can result in misuse if someone removes the gel contents from discarded patches.
- An opioid drug antagonist such as naloxone can help to correct OIRD symptoms.
- A sample that has been tested should not be considered safe.
- My only note is that the first test I did came out invalid because I over saturated the strip.
- They may be available through state and local health departments, syringe services programs, or drug stores and online retailers.
But a growing number of health and public policy experts are supporting their use along with other harm-reduction strategies. Fentanyl test strips are small strips of paper that were originally created to detect fentanyl in urine. But you can also use them to see whether a drug contains fentanyl in just a few minutes.

What Is Forensic Use Only?
Fentanyl test strips aren’t perfect, but most people find them easy to use. The best way to use them is to dissolve all the drugs you plan to use in water. Fentanyl might not be everywhere evenly in your product, so if you only test a portion of your supply you might end up missing it. Fentanyl stays in your system and can be detected by a drug test for 24 to 72 hours.
How Can A Person Be Sure That They’re Taking Real Fentanyl?
Call an ambulance right away if you suspect you or someone you’re with may have taken an overdose. Fentanyl patches pose a danger to kids who can stick them on their skin or mouths. This can cause death by slowing their breathing and lowering oxygen levels in their blood. This more recent version of fentanyl comes in bright colors. People who make it mix it with dyes and either press it into multicolored pills or sell it in a colored powder form.
As you immerse the strip in the urine specimen, the test will begin to process, and color will appear across the membrane.5. After the test strip has finished processing, take it out of the urine specimen cup and place it on a non-absorbent flat surface. Start the timer and wait for the colored band(s) to appear. Refrain from attempting to interpret the outcome after 10 minutes.
Is Fentanyl Addictive?
Fentanyl test strips from other sources may not detect all necessary fentanyl analogs. Some versions (mostly of Chinese origin) may not function at all. These strips work differently than the older, dark blue strips. For dilution ratios and more information, see our How to Test Fentanyl page.
Public Health
Food and Drug Administration (FDA) for the treatment of opioid use disorder. Another medication, lofexidine, has been approved for treatment of withdrawal symptoms.34 See “Medications for Opioid Use Disorder” for more information. Fentanyl is a synthetic opioid that is usually used to treat people with serious pain that lasts for a long time or after surgery. Under the care of a licensed doctor, fentanyl can be used as a legal medicine. Patients who are given fentanyl should be watched to see if they are misusing or abusing it.
General Health
Overdose prevention is a CDC priority that impacts families and communities. Drug overdose is a leading cause of preventable death in the U.S. Some opioids come directly from the opium poppy plant, but manufacturers make fentanyl in a lab and reproduce the chemical structure. One line is a positive result and means there is fentanyl in your drug supply. After a fentanyl treatment, you may have side effects that hinder your thinking and reactions or cause dizziness or drowsiness. Because of this, don’t drive or do activities that require you to be fully alert and awake after your treatment.
Doctors will only prescribe the fentanyl patch to people who are already tolerant of opioid therapy that is similar in strength. Fentanyl can continue to be effective after removing the patch, as the skin has already absorbed the drug. However, the amount of time it remains effective depends on the individual. Making fentanyl without a prescription is not an exact science.
A similar percentage chose to use their drugs with other people (instead of alone) so someone would be around to call 911 or give them naloxone (Narcan), if needed, to reverse an opioid overdose. However, people may not always know fentanyl is present. It is being sold as powders, nasal sprays, and more and more pills that look like real prescription opioids. Because there is no government oversight or quality control, these fake pills often have lethal doses of fentanyl and none of the drug they were supposed to contain.
While it’s safe for your doctor to give you fentanyl in a medical setting, some people abuse it, which can lead to an overdose. Fentanyl test strips can identify the presence of fentanyl in unregulated drugs. They can be used to test injectable drugs, powders, and pills.

Fentanyl is also a drug subject to diversion for misuse. Fentanyl can be added to heroin for increased potency or be distributed under the guise of highly potent heroin. A person taking prescribed fentanyl can experience dependence, meaning they have withdrawal symptoms when they stop taking the drug. Illegal drugs, such as heroin and cocaine, are sometimes mixed with fentanyl, which makes the drugs more potent. If someone with a substance use disorder is unaware of the added fentanyl, this can put them at a higher risk of accidental overdose or death. These strips utilize a superior antibody with greater specificity to fentanyl, and as a result, are the most reliable strips on the market for drug checking and harm reduction purposes.
