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:
“I have a blood bolt
and I have made it mine.
With this man I take in hand
his destiny and with this gun
I take in hand the newspapers and
with my heat I will take him.”
—Anne Sexton (1928–1974)
“Men hear gladly of the power of blood or race. Every body likes to know that his advantages cannot be attributed to air, soil, sea, or to local wealth, as mines and quarries, nor to laws and traditions, nor to fortune, but to superior brain, as it makes the praise more personal to him.”
—Ralph Waldo Emerson (1803–1882)
“He was a fool—a brilliant man and I loved his beard, and there was the mountain ax in his brain, and all the blood poured out, and he could not see the Mexican sun. Your people raised the ax, and the last blood of revolutionary mankind, his poor blood, ran into the carpet.”
—Norman Mailer (b. 1923)
