Know About Pre-Employment Marijuana Drug Test

Marijuana is an highly used illegal drug in the United States. In order to detect the usage, marijuana drug test is conducted at different places. There are several types of drug testing methods like saliva drug testing, blood drug testing, urine drug testing, hair drug testing.

Employer of an organization expects the environment to be clean and safe. For making the work environment safer, he wants to choose the right employee for their job. Apart from conducting several skill testing, they even made drug testing as mandatory for preventing the accidents.

As this test will be done for so many people at a time and randomly, the most cheapest and effective test will be the urine test. Although, Urine test cannot determine the THC psychoactive component of marijuana, it can detect the non-psychoactive component of marijuana for THC-COOH. As detection periods for occasional users will be from 1 to 7 days and for chronic users it will be detected from 7 to 100 days.

If you want the immediate result, saliva drug testing can be used. But, unlike the urine test one cannot perfectly detect the presence. Blood test gives the accurate and perfect result for the recent drug usage, but this test is not used because it is expensive. Hair test also can be done, but the recent use cannot be detected.

But generally urine test is performed as the marijuana is much sensitive to this test. Once the job applicants marijuana drug test results are out, depending on the result i.e., if the result is negative then he will be employed by the employer.
