What Are Cannabinoids?

Drug tests can detect marijuana in your urine, blood, hair, and saliva.

Drug testing is a common practice in the United States. Current and future employers will often ask employees to undergo a drug test.

Drug tests for marijuana usually measure levels of THC or its metabolite, THC-COOH. Depending on the testing method, traces of marijuana can be detected for days, weeks, or even months after last use.

Urine testing is the most common way of screening for marijuana use. Other drug testing methods include blood tests, saliva tests, and hair follicle tests.

Let’s take a look at each of these drug testing methods, the detection period for marijuana, and the best ways to clear marijuana out of your system.

What is a drug test and what does it check for?

A drug test for marijuana is the analysis of a biological sample to determine how much of the drug is in your system.

Screening prior to employment Testing for those in security or military positions Safety precaution for those operating heavy machinery or vehicles Testing as a deterrent to prevent drug use in schools, companies and government departments Routine testing as part of a drug program Believed to have been impaired at work Involved in an accident Returning to work after a substance abuse treatment program (Photo: Shutterstock) (Photo: Shutterstock) See Also (Photo: Shutterstock) Fasting is another way of burning body fat that might help when it comes to passing a drug test. Taking Vitamin B may also work along with drinking extra water. As an excess of water in the system can make urine clearer, taking Vitamin B can add to creatinine levels and the color of the urine. Drinking a diuretic like cranberry juice or coffee might also help to encourage urination, but there is little evidence that it helps with passing a drug test. Using an over-the-counter diuretic may help but can be detected. Excuses don’t cut it. It is difficult to challenge a positive test outcome no matter the reason. Trying to spike or spoil a urine sample with an adulterant like eye drops, detergent, nitrites, glutaraldehyde, oxidizing agents such as bleach and hydrogen peroxide, vinegar, lemon juice or other commercially sold products can easily be detected by testing labs. There is no evidence that herbal teas, urine cleansers/detoxes, goldenseal, niacin, lecithin, activated charcoal or vitamin C will help with passing a drug test. Trying to substitute a urine sample is deception. Testing labs will usually measure various parameters (such as pH levels and temperature) to ensure that a urine sample is normal. Using pain relievers like ibuprofen will not interfere with a drug test. (Photo: Shutterstock) SIGN UP
