WOW! I feel like I'm back at the pharm company! ::flashbacks::

You are right. But depending on what type of disposable kits are used and when the tests are done, positives are possible.

We saw this with poppy seeds.

So, from your post, it would be a yes if someone was submitted for a medical examine.

But it would not be the case for those test kits that are sent for onsight quick tests.

LOL, I wasn't even thinking about disposable kits! Not to inform you of my "personal habits", but I've had to pee in the bottle so many times for job requirments over the years that I just naturally assumed they were sending samples to the lab.

Here's a FAQs page on cotinine measurements from a lab. It's pretty accurate from my knowledge. However, I recall there can be as much as a 400 fold variance due to individual's ability to metabolize nicotine efficiently.
