Marijuana is one of the most illicit drugs used in the United States. The most active component in the drug is tetrahydrocannabinol (THC). Marijuana drug testing is performed to find if a person has consumed marijuana or not. The presence of THC is detected during marijuana test.
Marijuana drug testing provides many benefits for companies and parents. Marijuana drug test is an easy and accurate process. Marijuana drug test is conducted by using hair follicle and body fluids. Body fluid testing includes detection of THC in body fluids such as urine, saliva, and blood. Most commonly used sample for marijuana drug testing is urine. However, others are also used based on the situation. Blood tests for marijuana detection are most expensive when compared to other fluid tests. However, it is the most accurate of all tests.
The other method of testing the drug is by hair follicle. The drug traces can be traced by hair testing for up to 90 days after consumption. The compound of marijuana gets deposited in the hair shaft and hence it can be detected even after a long time of drug use. Marijuana drug tests are done only to detect the presence of drug in the individual. These tests do not determine how much amount of drug was taken and when the drug was taken.
Marijuana can be detected in an individual during certain time periods. The amount of drug taken by a person also varies with the time period as to how long it can be detected. If the drug is consumed by a person only once, then detection of the drug by urine test can be done for 48 to 72 hours after usage. However, if the drug is consumed by a person is chronic or habitual, then the drug can be detected for up to 12 weeks after drug use. This depends on factors such as duration, quantity, and frequency of drug usage.
