    The chemical name of THC is delta-9-tetrahydrocannabinol and its metabolites can be identified with marijuana blood tests. It is possible to get a false positive for marijuana which means that the THC test reads positive although marijuana was not used. The fear of registering a false positive scares almost every individual who is going to face a drug testing for marijuana. But there is no need to worry as with the latest drug test laboratory techniques, the results are usually conclusive for the presence or absence of marijuana.

    Blood tests to detect the use of marijuana are done only in specific cases such as in case of road accidents, autopsy and to check for the intoxication content in the blood. Blood tests are effective in determining the recent use of marijuana since THC can be detected in the blood. This test is not preferred more owing to the fact that a blood drug test is more expensive method of testing than any other tests and because of the inconvenience of specimen collection. A positive for marijuana can be obtained by a blood test within a few hours of the last use of drug. Regular and chronic smokers may test positive even after a day or two. The period of time for which THC can be detected depends upon a number of factors like body mass, frequency and quantity of drug used and the body metabolism rate. Thus it is inconvenient to determine the exact time for which drugs can be detected in the system.
