    Thc Drug Test How Long

    Read about THC drug test how long.

    THC is one of the major ingredients of marijuana. A marijuana drug test is the analysis of urine, blood, hair and saliva to determine the presence of THC in the body of an addict. Delta-9-tetrahydrocannabinol or THC and its metabolites can be identified even if marijuana was not used. It means that it gives a false positive result.

    The quantity and duration as well as the frequency for which marijuana was used are responsible for the duration of time during which THC can be detected in the body of the doper. Generally they can be detected between 10 to 14 days after the intake of marijuana. But for consistent users, the THC can be detected between 30 to 90 days after the use of the drug. Urine test can very well detect them and are often used. They are very accurate since the byproduct THC-COOH is secreted along with the urine and it stays in it for several weeks.

    The breakdown product can be detected in urine even in urine days or even weeks after stopping its use, depending upon the person whether a regular or an occasional marijuana indulger. Urine test cannot detect the current use of marijuana but gives an idea about the use of the drug test accuracy in the past. The metabolite of THC gets stored in the fatty tissues and thus can also be detected after a very long period.

    In case of a blood test, the positive result can be obtained within a few hours of marijuana use. Regular users may get a positive result even after a day or two. Metabolites can be detected in saliva for 12 to 14 hours to a maximum time period of 3 days after the intake of marijuana. It is one of the most convenient THC drug testing since it is quick and cheaper too. One cannot cheat a saliva test because the specimens are obtained under supervision.

    Hair test are the most reliable methods and can detect long term drug use even after months of intake. THC gets passes through the scalp and gets deposited in the hair shafts. Also a small sample of hair from any part of the body can detect the drug.
