Yes, but the doctor has to specify that he/she wants the blood tested for nicotine.
NO general blood test will not show nicotine
depends on when you last smoked but. i think..
I'm taking a nicotine eceryday 4 times a day for pain and my doctor tested me and said that it didn't show up in my blood how is that.
Different body types and metabolism will affect how long nicotine will remain in your system but typically around 90 days.
