Brief Answer:
In my opinion, you should pass the test; best of luck

Detailed Answer:
Hello sir and welcome.

Thank you for writing to us.

I have gone through your query with diligence and would like you to know that I am here to help. If you have the test today you should pass as cotinine stays in the body for about 5-8 days from my experience with patients, and as it has been about 8 days since your last cigarette, you should pass the test sir. But it would be better if you waited about a day or 2 to get tested, to be on the safer side.

I hope you find my response helpful and informative. Please feel free to write back to me for any further clarifications, I am always here to help.

Best wishes.
