[25 Pack] Fentanyl Test Strips for Rapid Detection - Carethetic Fentanyl Test kit - High Sensitive & Reliable Quality, Easy to Use & Read FTS Test Strips

I love being able to test anything for fentanyl. It's so scary how much its found in other substances, you can never be too safe

Fast results!

Tested several things, all negative. Follow up human testing has verified negative test results. Thankfully, have yet to see a positive test result, nor a false negative.

Great product

Half the time tap water tests positives

This is a must have for any recreation or medicinal user of "street-based" substances or anyone else that may consume anything that could possibly become contaminated with fentynal. This is an extremely dangerous substance and should be avoided at all costs. And you would be surprised to find how many other substances, not even in the same type category, now contain the substance! These strips are very accurate and versatile, being able to test substances and urine all with the same strips. And they sense even the slightest bit of presence of the substance. Just be aware that even the faintest second line is a negative. Sometimes its so light you can hardly notice it and interpret the results as a positive. So look at it very close in a couple different lighting settings. Highly recommend!

This company sells you quantities strips that don’t work the way you would think it works

After those Kansas guys died after the playoffs of fent poisoning I thought it certainly cant hurt to test from now on. Super easy-was negative this time 👍
