How Long Cannabis Can Be Detected
People often ask how long cannabis stays in your system because detection times vary based on frequency of use, body type, and the type of test used. This guide explains the main factors that influence how long cannabis can be detected.
Main Factors That Affect Detection
Detection time is not the same for everyone. Frequent users tend to retain fast cannabis shipping metabolites longer than occasional users, and body fat, hydration, and metabolism also play a role
.
The type of product and potency can also matter, since higher THC levels and regular use lead to more buildup in the body over time
.
Typical Detection Windows by Test Type
Urine testing windows range from a few days to several weeks depending on use patterns.
THC clears from blood faster than it does from urine.
Saliva tests typically detect cannabis for about 24–72 hours, with longer windows possible in frequent users
.
Hair tests can detect cannabis use for up to 90 days or more, because metabolites become trapped in growing hair over time
.

How long cannabis stays in your system depends on frequency of use, body factors, and the type of test. Urine, blood, saliva, and hair all have different detection windows
