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:

    If I’ve killed one man, I’ve killed two—
    The vampire who said he was you
    And drank my blood for a year,
    Seven years, if you want to know.
    Sylvia Plath (1932–1963)

    If a man also lie with mankind, as he lieth with a woman, both of them have committed an abomination: they shall surely be put to death; their blood shall be upon them.
    Bible: Hebrew Leviticus 20:13.
