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.

    “The blood of Abraham, God’s father of the chosen, still flows in the veins of Arab, Jew, and Christian, and too much of it has been spilled in grasping for the inheritance of the revered patriarch in the Middle East. The spilled blood in the Holy Land still cries out to God—an anguished cry for peace.”
