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 mind is “ashamed” of the blood. And the blood is destroyed by the mind, actually. Hence palefaces.
    —D.H. (David Herbert)

    See, see where Christ’s blood streams in the firmament!
    One drop would save my soul—half a drop! ah, my Christ!—
    Ah, rend not my heart for naming of my Christ!—
    Yet will I call on him!—O, spare me, Lucifer!—
    Where is it now? ‘T is gone; and see where God
    Stretcheth out his arm, and bends his ireful brows!—
    Mountains and hills, come, come and fall on me,
    And hide me from the heavy wrath of God!
    Christopher Marlowe (1564–1593)

    Religion! How it dominates man’s mind, how it humiliates and degrades his soul. God is everything, man is nothing, says religion. But out of that nothing God has created a kingdom so despotic, so tyrannical, so cruel, so terribly exacting that naught but gloom and tears and blood have ruled the world since gods began.
    Emma Goldman (1869–1940)
