Exploro Nicotine Test, Cotinine Urine Strips, 10 Pack

It works. I never could get both bars on the test strip to show up identically. The nicotine line was only slightly filled in, much more faded than the control line. However on day 14 of no nicotine i used a test strip and got a really faded line, but then passed a urinalysis on the same day. Sooo, advice, you don't need to wait for a solid line, a faded line is ok. I actually got a faded line on day 8, but the line was so faded I had to hold it to a lamp to see it. I don't know if i would have passed that day. The instructions say you should test negative after 10 days and that seems to me to be a good average. I wouldn't risk doing it before.

It works

Perfect product Perfect service

Easy to use. Results are clear to see.

These test strips work well for detecting vape use with nicotine. It says it detects nicotine for up to 10 days but I think that varies. What I have noticed is that when my son vapes on the same day, the positive appears very positive. A few days after vaping, the negative line starts to appear very faint at first, but day by day the negative line gets darker and darker if he hasn’t vaped. So not all negatives are created equal as the packaging suggests. I learned there was a pattern with consistent use of these test strips. Overall, great quality for the price.

I had to stop for a surgery. And of course I waited to the last week of the test. I stopped on Sunday, actually I took a couple of puffs that morning. I drank a lot of water like anyone would do and tested on Wednesday evening and I was cleaning by then. Double checked again before I got to the hospital on Friday morning to mack sure the first test was right and I was lucky that I was clean so yes I trust these. But I don't suggest anyone wait until the last moment like I did. It's not smart plus your system may not flush as quickly as mine did.

Works great, easy to use.

Results are quick and accurate to the best of my knowledge. My husband found an old empty vape package I had hid who knows how long ago that I didn’t even remember was still in the house and he didn’t believe me when I told him I’m clean. Ordered these of my own volition and took a test as soon as they arrived. Negative result just as I knew it would be. He also used one and it was also negative like it should’ve been. Plenty leftover that we won’t use but I would absolutely order these again and recommend them to anyone that just *needs to know* without any doubt whether someone has been smoking/vaping or not.
