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:
“One memorable addition to the old mythology is due to this era,—the Christian fable. With what pains, and tears, and blood these centuries have woven this and added it to the mythology of mankind! The new Prometheus. With what miraculous consent, and patience, and persistency has this mythus been stamped on the memory of the race! It would seem as if it were in the progress of our mythology to dethrone Jehovah, and crown Christ in his stead.”
—Henry David Thoreau (1817–1862)
“The cup of blessing that we bless, is it not a sharing in the blood of Christ? The bread that we break, is it not a sharing in the body of Christ?”
—Bible: New Testament, 1 Corinthians 10:16.
“Of Eva first, that for hir wikkednesse
Was al mankinde brought to wrecchednesse,
For which that Jesu Crist himself was slain
That boughte us with his herte blood again—
Lo, heer expres of wommen may ye finde
That womman was the los of al mankinde.”
—Geoffrey Chaucer (1340?–1400)
