I smoke and I have to get blood work for high pressure because my mom is freaking out and blood pressure runs in the family. Will nicotine show up in the test? How long does nicotine stay in your system? I know smoking causes high blood pressure but I had it before I started smoking.
Best Answer: A doctor doesn't take blood to measure your blood pressure. Why do you want to know if nicotine will show up in your blood, If you have high blood pressure it is important to tell your GP that you smoke, because you may need help to give up smoking.
