One of the most common questions around cannabis use is how long weed stays in your system. The answer isn’t always straightforward, because THC—the main psychoactive compound in cannabis—interacts with the body differently depending on a variety of factors.
Whether you’re curious for personal knowledge or trying to better understand how cannabis affects the body over time, learning how THC is processed can help set realistic expectations.
How THC Is Processed in the Body
When cannabis is consumed, THC enters the bloodstream and is then broken down by the liver into metabolites. These metabolites are stored in fat cells and released slowly over time, which is why cannabis can remain detectable long after the effects wear off.
Because THC is fat-soluble, it behaves differently than substances that dissolve in water. This is one of the main reasons detection timelines vary so widely.
How Long Weed Can Stay Detectable
There is no single timeline that applies to everyone. However, research and clinical observations provide general ranges.
According to Priory Group, THC metabolites may remain detectable in the body for several days to several weeks, and in some cases, up to 90 days, depending on usage patterns and individual factors.

Factors That Affect Detection Time
Several factors influence how long weed stays in your system, including:
- Frequency of use – occasional use clears faster than regular use
- Potency – higher THC levels may take longer to process
- Consumption method – edibles often last longer than inhaled cannabis
- Body composition – THC is stored in fat cells
- Metabolism – everyone processes cannabinoids differently
Priory Group highlights that regular or long-term cannabis use increases the likelihood of THC metabolites remaining in the body for extended periods.
Different Types of Testing and Detection Windows
Detection time can also depend on how cannabis is being tested:
- Urine tests are the most common and may detect THC metabolites days or weeks after use
- Blood tests typically detect more recent use
- Saliva tests usually reflect use within the past 24–48 hours
- Hair tests can show longer-term patterns, though they are less frequently used
Importantly, these tests detect past exposure, not current impairment.
Why the Experience Is So Individual
Two people can consume the same product and have very different detection timelines. This doesn’t mean something is “wrong”—it simply reflects how unique each body is.
Factors like hydration, activity level, and overall health can all influence how cannabinoids are processed and released over time.
Making Informed Cannabis Choices
Understanding how long weed stays in your system can help people make more informed decisions about cannabis use. Awareness of potency, timing, and personal tolerance can lead to a more comfortable and predictable experience.
At Orange County Cannabis Co., we believe education is a key part of responsible cannabis use. Asking questions and learning how cannabis interacts with the body empowers people to choose what works best for them.
Final Thoughts
Weed doesn’t leave everyone’s system at the same pace. Detection time depends on a combination of biology, habits, and product choice. Reliable information from trusted sources like Priory Group helps cut through misinformation and provides realistic expectations.
When it comes to cannabis, understanding the process is just as important as the product itself.
