Ok, sorry, asked this in Vets, but asked it again in "noobs". Need to tame a blood test a d sign a "tobacco-free " affidavit. Whereas I do not smoke analogs anymore, I don't know how this will show up. The affidavit doesn't bother me cause I am NOT using tobacco, but I havt to wonder how it shows up. I did read an old thread... I vape with a Smoketip, 2-3 16 mg cargos per day. Any idea what I can expect from the blood test or how much I need to refrain in the days ahead? Running out of time, please help!!
The half-life for Nicotine in the blood is quite variable, but is generally 1-4 hours. This means that your blood levels will halve every 1-4 hours. Cotinine is also measurable via blood test, and is a metabolite of nicotine. Its half-life is quite a lot longer, at ~20 hours.
If the issue is tobacco usage (which it probably is), I'd suggest getting some nicotine gum and using it. When you show positive for either nicotine or cotinine, you can simply say that you quit using tobacco some time ago but still use nicotine replacement therapy to remain abstinent. As another poster mentioned, a carbon monoxide test would show that you're not smoking.
If you are doing a blood test and wish it to be negative, you'd have to be off all nicotine for quite a long time in order to test negative. Probably 30 days, would be my guess, if they check for cotinine. Less if they test for just nicotine (10 days would seem a reasonable guess).
Good luck!
