How Long Does Nicotine Stay In The Blood Stream?

My insurance company is requesting blood/urine samples - I have not had a cigarette in 8 days and have been taking Chantix, as prescribed, for the last 12 days. My question: Will my past nicotine usage show up in a blood or urine test? And will the Chantix also show up in those tests

Hello,

As per your query regarding duration, I would say, it stays in saliva for around 5 to 6 days or sometimes more as it depends on your metabolism and upon many factors. However, in body system, it stays for around 24 hours.

You can reduce nicotine levels by drinking plenty of water. The more water consumed, the more nicotine released from the body through the urine. Eat fruits and vegetables.

They can help metabolize the nicotine out of the system. Chances of your test positive are less. Nicotine stays in blood system for less than 24 hours.

Many factors like frequency of smoking , amount of smoking and individual body reaction towards smoking also depends for stay in body.

Hope I have answered your query. Let me know if I can assist you further.

Regards,
