I have a physical in about 7hrs. They'll be taking a urine sample to test for marijuana and will be taking a blood sample. I quit smoking 2 weeks ago when I found out about the test and when I did smoke it was never much. One hit before my morning workout about 2 to 3 times a week. I bought a detox drink for peace of mind but now it's hitting me that I have to give a blood sample and have been asked not to eat anything today before the test. Should I not drink the detox drink? Do you think that will show something off in my blood work? Anybody have any experience with this?
