Unsure
My boyfriend has lied previously several times about sneaking tobacco. Decided I would do a test. It came up a clear and quick positive. He doesn't know why it came up positive...He is calmly telling me it shouldn't be positive.There was another comment about false positive, I'm just unsure if this one was false positive, too.

Always arrived when it should and was a life saver ...
Always arrived when it should and was a life saver, gave up smoking, but on occasion drink far too much and so can't remember if I've smoked or not, sounds ridiculous I know, but have found it to be very reliable!

I dislike that this text give a false result because I do not smoke and it came up positive....
