Drug Detection Periods in Drug Tests
drug testing

How long drug test kits can find drugs in the human body?

Drug detection periods refers to how longs drugs are detectable in the human body using, in the case of this table, four major sources (urine, blood, saliva & hair). The most common used method to drug test are urine drug test kits and saliva drug tests. The drug detection window will depend on factors like drug class, frequency of use, metabolism and others. Saliva Drug Tests will mimic the same metabolites that blood detects with the exception of marijuana THC and benzodiazepine, in which the window of detection is much smaller than urine.

How long does weed stays in your system

Weed as marijuana is commonly known will have longer detection times than other drugs. Most of the time parents, employers question how long weed does stays in your system and if second hand smoking of marijuana can affect the results in a drug test. Marijuana stays in the system depends on a number of variables, unique to every individual and different drug testing techniques.

In most cases, you will not test positive for marijuana from second hand smoke. To put it in perspective, a recent study conducted by the Legal Institute of Medicine in Germany examined eight people who were exposed to second hand marijuana smoke in a well-trafficked cannabis shop for three hours. None of the subjects reached a urine THC level higher than 25ng/ml. Only in instances where the area was so smoke-filled with weed that it irritated the eyes would there be a potential for you to test positive for marijuana from second hand smoke.
