Why Test for Fentanyl?
If used within the bounds of medicine, as advise and under direction, Fentanyl can use to treat chronic pain. It is 50-100 times more potent than morphine. Unfortunately, the use of this illicit drug is leading to a growing number of overdose deaths in the United States and abroad. Â
The rise in opioid usage (a type of drug that includes heroin, fentanyl, oxycodone, hydrocodone, codeine, morphine, etc.) has devolved into an epidemic that has taken a violent toll on society for the past 20 years. The opioid epidemic has claimed hundreds of thousands of lives (over 800,000) in the U.S. since the 1990s. It began as an increase in overdoses from prescription opioids. This is one of the drugs that is of most concern when urine drug testing.
Using The Fentanyl Drug Test Kit
The Fentanyl Drug Dip Tests are a very exact urine drug testing solution. It can be used to detect the presence of fentanyl in urine.
Additional Information:
The fentanyl urine drug test kit contains a cutoff level of 20ng/ml. Moreover, use it exclusively to detect the use of fentanyl in the urine. If stored in a refrigerator, bring the dip test to room temperature before use.Â
- Economical. You don’t even have to spend an arm and a leg to fight overdose or use these fentanyl drug dip tests or kits for your rehab, clinic, workplace, or academic institution.
- Also, we can give them to you for as low as $0.29 per Fentanyl Drug Dip Tests.
Side Effects of Fentanyl
Akin to morphine and heroin, fentanyl generates the feeling of relaxation, pain relief, and drowsiness. People who use drugs like this may also experience a high level of euphoria as well. It does so by targeting opioid receptors in the brain that are responsible for mediating emotion and pain.
Fentanyl also releases dopamine (a chemical that induces the feeling of pleasure) in the reward center of the brain. This is how repeated use of fentanyl reinforces the user’s dependency on the drug.
Individuals on fentanyl are often dizzy, in a state of confusion, have pupillary cramp (shrunken pupils), and may feel nauseated. Opioid poisoning or overdosing leads to near-unconsciousness, coma, cold-bluish skin, respiratory failure, and death. Sadly one of the direst consequences of fentanyl use is opioid overdose.

All Orders Will Be Shipped the Same Day If Placed Before 3:00 PM EST.
Next-day Shipments Will Not Be Delivered on Weekends, and That the Time Taken on Air Shipments Should Be Counted as Business Days.

Why Does My Tracking Info Still Say "Label Created, Not yet in the System" When I Placed It X Days Ago?
If your order was placed via USPS, sometimes your label might not show up in their system even 1-3 days after they have received the package. The same can happen for UPS orders, although they almost always show up in their system the night which they are shipped. If you have any questions regarding the status of your order, please contact us and we will investigate the matter.
If I Pay for a next Day Air Delivery, Am I Guaranteed to Receive It the next Day?
Air deliveries performed by UPS are counted via business days, so you will receive your package the business day after it has been shipped. We also do not ship orders placed after 4 pm EST on the same day, so Next Day orders placed after 4 pm will be shipped the following business day.
Why Can't I Check the Tracking of My Package?
After you place your order, an email will be sent to you with the tracking number within a business day. If you did not receive this email, it's possible that the e-mail was entered incorrectly, sent to your spam folder, or blocked. If you did not receive this email, please call or email us and we'll be happy to give you the status of your shipment.
I Placed My Order but I No Longer Need It. Can I Return It and Get a Refund?
We accept returns for unused items as long as they are placed within 30 days after the day they are purchased. Although shipping is free upon order, we still incur a cost for every order that is shipped, and you will be refunded the amount of your order once we receive the returned goods, minus the cost of shipping.
