...blood tests determine how long..? Will sweating and drinking a lot of water help me pass a drug test for marijuana? Does blood tests determine how long a person has been smoking for? I am getting tested tomorrow and what I've been doing for the past couple of days were waring plastic bags and large amounts of clothes over it and going into my car at the same time blasting the heat to make me sweat. I also drink large amounts of water everyday. However what I hear is that this place is going to do a urine test and blood test. My parents told me the blood test is to see how long i've been smoking marijuana for. Is that even true that blood tests can determine how long one has smoked for? If you have any advice please help!
