How long does Marijuana stay in the body and is detectable a drug testing kit?

Marijuana is the most common drug used and in fact has the highest positive rate in all drug testing types. Marijuana is also a drug that is more likely to stay in the system for days, weeks, or even months after use.

The answer to the question "How long does marijuana stay in the body" will depend on many factors including below will affect how long marijuana will stay in the body.

• Weight. Metabolism slows with increased weight and body mass resulting in longer marijuana use detection periods.
• Age and Health. Deteriorating health and older age results in longer detection period
• Frequency of use. Quantity of marijuana used each time and how long consistent marijuana use prior to testing will effect the detection period. Single, isolated, small doses are generally detectable at a lower boundary. Chronic and long-term use typically results in detection periods near or at the upper boundary.

Here is a table that summarizes the drug testing detection windows of different drug testing methods (assuming above factors all being average)

SUBSTANCE	SALIVA	URINE	HAIR
Marijuana (light use)	1-2 days	2-4 days	up to 90 days
