One of the most common questions people ask about cannabis isn’t about strains or THC percentages, it’s how long cannabis stays in your system.
Whether you’re curious for personal reasons, workplace policies, or general education, the answer isn’t one-size-fits-all. Detection time depends on how you consume cannabis, how often you use it, and how your body processes cannabinoids.
This guide breaks it down clearly, without scare tactics or misinformation.
What Does “Staying in Your System” Actually Mean?
When people ask how long cannabis stays in their system, they’re usually referring to drug testing, not how long they feel high.
Most drug tests do not look for active THC. Instead, they detect THC metabolites, primarily THC-COOH, which is produced after your body processes THC.
This is why someone can feel completely sober while still testing positive days or weeks later.
How Long Cannabis Can Be Detected (General Ranges)
Detection time varies by test type and consumption habits. Below are general educational ranges, not guarantees.
Urine Tests (Most Common)
- Occasional use: ~3-7 days
- Regular use: ~10-30 days
- Heavy daily use: 30+ days in some cases
Saliva Tests
- Usually detectable for 24-72 hours
- More likely to catch recent use
Blood Tests
- Typically detectable for 1-2 days
- Rarely used outside of specific situations
These ranges are influenced by many personal factors, which we’ll cover below.
Does the Method of Consumption Matter?
Yes, but not in the way many people think.
- Enter the bloodstream quickly
- Effects wear off sooner
- Metabolites still linger after effects fade
- Metabolized through the liver
- Produce stronger metabolites
- Can sometimes extend detection time slightly
Even though edibles feel different, no consumption method guarantees a shorter detection window.
What Affects How Long Cannabis Stays in Your Body?
Several factors influence detection time:
- Frequency of use (occasional vs daily)
- Body fat percentage (THC is fat-soluble)
- Metabolism
- Potency and dosage
- Hydration and overall health
Someone who uses cannabis occasionally may clear metabolites much faster than someone who consumes daily, even if the dose is similar.
Legal Cannabis vs Drug Testing: Important Context
Even in legal states like California, drug testing policies may still apply depending on employment, probation status, or federal regulations.
Legal cannabis use does not automatically override testing requirements, which is why education around detection is still important for many consumers.
Common Myths to Avoid
- “Drinking water will flush it out”
Hydration helps overall health, but it does not eliminate metabolites instantly. - “Low THC products won’t show up”
Even small amounts of THC can metabolize into detectable compounds. - “Edibles are safer for tests”
Not necessarily, metabolism plays a larger role than format.
The Takeaway
Cannabis detection isn’t about how high you feel, it’s about how your body processes cannabinoids over time.
Understanding how long cannabis can stay in your system helps consumers make informed decisions, especially in situations where testing policies apply.
