Thanks to this test I saved a lot of time and money not having to retest at the doctors office.

Bought these to test my teenagers. My kiddo drank a detox and tons of water. It still detected it. However, I took one after second hand smoke exposure and it was negative. Worth the money.

Was able to detect nicotine in the expected time frame. First test came back positive (as expected). Tested a few days later (after the 7 day window for detection) and it came back negative (as hoped).

4.0 out of 5 stars faint line

I've been testing my son for months with this test and a more sensitive test (tests for 100) and he finally tested negative with the more sensitive one. On this test, I could BARELY see the line if I put on glasses and squinted. If the more sensitive test was easy to see, this should have been even easier. My husband and I tested, and the line was very dark. Why would the line on the more sensitive test that detects even smaller amounts of nicotine be easier to see than this one? And if someone is negative, they are negative. The line should be the same color between people, right? Because if ANY nicotine was detected, there wouldn't be a line at all. It's just very confusing.
