Detection interval — the quantity of time following a person consumes a drug a drug test can still show a positive outcome. By means of example, after someone consumes marijuana, a marijuana urine drug test can detect the drug for about around a week then and possibly longer — up to a month.
By means of example, the body takes longer to flush out orally ingested marijuana, compared to if it’s smoked.
Drugs undergo these specific procedures the moment they are ingested into the human body and are detectable in urine, blood, saliva and hair through drug testing in a particular window of time from ingestion until all traces are flushed out of the system. This window of time is referred to as the drug detection period.
Cutoff level — the minimum amount of a drug that has to be present in a specimen in order for it to be considered positive. By means of example, the cutoff level for marijuana in a urine specimen for an immediate testing kit is 50 ng/mL.
Metabolism is a set of biochemical reactions, transformations and processes that exist within the cells; through the digestion of food, the transport of substances between different cells, the conversion of said compounds (accumulations or breakdown) into energy to maintain the human body and the subsequent elimination of waste materials.
Factors That Affect Drug Detection Time
Age — The body’s metabolism slows down with age so older drug users keep substances longer in their system. It’s therefore more challenging to flush out drugs from the machine of an individual with loads of body fat.
