What Triggers a Positive Result in a Marijuana Drug Test?

Every drug test yields a positive result if there are enough drug metabolites in the sample to indicate drug use. The THC metabolites will usually stay in your urine for a week or two but those who heavily use marijuana will end up with it staying in their urine for up to a month. Traces of marijuana can stay in your hair for a few months. So what is THC?

THC is the part of marijuana that gets people high. Medical marijuana does not contain THC. THC is just acronyms for Tetrahydrocannabinol. THC is the most potent ingredient in marijuana and is what is looked for in a marijuana drug test. If the THC metabolites are found in the urine sample, it will trigger a positive result for marijuana usage.

When marijuana is smoked, the drug chemicals will travel in your body. The drug will be processed and the THC metabolites will travel to different areas. The metabolites will land in your blood, urine, saliva, hair, and virtually everywhere in your body. The metabolites will stay in various areas for a different amount of time. With your hair, the chemicals slowly release but with your saliva and urine, the chemicals go away quicker.
