Prime Screen [10 Pack] Nicotine Tobacco Cotinine Urine Test Kit - Urine Dip Card Testing Cotinine from Smoking - WCOT-114

Item works well I was sceptical after reading reviews but I did multiple test against me and my friend who vapes to ensure I was negative and I was it didn’t give any false results.

Did the job! Pre operation test. Worked and easy to use.

Quick and prompt delivery

Yes it works. But I've found a few days after testing the first time the test line was lighter. It was darker on the first test. I've not had no nicotine or anything else. So umm don't know what to think. I've bought other brand as im having surgery and need to be nicotine free.

Caught our teenager vaping, she recommended testing to prove 🤦‍♀️ she wasn’t. I didn’t even know there was such a thing. Of course Amazon has something. This product shows when there’s nicotine in your system. I had a friend smokes try it and it works.

Phenomenal 6 days smoke free smoking a 0 mg nicotine geek bar pulse X for the past five and a slow taper of four or five days previous to completely stopping I used to smoke anywhere between 28 to 30 cigarettes a day easy on the 10th I was told I was going to be having surgery severe surgery and I have to be smoked free I smoked the same amount that day the next day I went down to four the day after two and a half the day after that one and a half the day after that a half of one and then a couple Puffs the next day and now I have completely been 6 days smoke free and I am happy to say I tested negative I took two tests back to back just because I wanted to be sure both negative light negative but definitely negative my test is on the 29th for surgery my doctor won't even put you on the schedule unless you're off of nicotine definitely worked I will definitely purchase again if I ever need to hopefully I will not because I plan to stay smoke-free I started to strip the Chantix today and I plan to stay nicotine free definitely buy these though they work!!!! Just remember even if it's a Faded Line it's a negative doesn't have to be a dark line just has to be a line!!!

Seems insanely accurate. Tested on myself who doesnt smoke and on someone who vapes and immediately the results showed positive for them and negative for mine.

I’ve purchased these 2 times already they’re super accurate. I use them often as well when I decide to smoke here and there.

They work great I have a surgery coming up and had to be Cotinine free. They showed that it was still in my system for 3 week and finally started to come up (COT) Free. If you’re a parent wanted to test a child or just want to see your progress while you stop smoking. For some reason it did help me with being able to quit it was like a game.
