Blood
Drug-testing a blood sample measures whether or not a drug or a metabolite is in the body at a particular time. These types of tests are considered to be the most accurate way of telling if a person is intoxicated. Blood drug tests are not used very often because they need specialized equipment and medically trained administrators.
Depending on how much marijuana was consumed, it can usually be detected in blood tests within six hours of consumption. After six hours has passed, the concentration of marijuana in the blood decreases significantly. It generally disappears completely within 30 days.
Famous quotes containing the word blood:
“The Indian attitude toward the land was expressed by a Crow named Curly: “The soil you see is not ordinary soil—it is the dust of the blood, the flesh, and the bones of our ancestors. You will have to dig down to find Nature’s earth, for the upper portion is Crow, my blood and my dead. I do not want to give it up.””

“I, a spinning man,
Glory also this star, bird
Roared, sea born, man torn, blood blest.”
—Dylan Thomas (1914–1953)
“His [O.J. Simpson’s] supporters lined the freeway to cheer him on Friday and commentators talked about his tragedy. Did those people see the photographs of the crime scene and the great blackening pools of blood seeping into the sidewalk? Did battered women watch all this on television and realize more vividly than ever before that their lives were cheap and their pain inconsequential?”
—Anna Quindlen (b. 1952)
