Cannabis Half Life
Cannabis half-life explained: how long THC and CBD take to clear your body, what changes the timeline, and what it means for detection windows.
Introduction
Understanding the half-life of THC in different body fluids is important for individuals who need to know when cannabis use will no longer be detectable through testing.
What is THC Half-Life?
The half-life of THC, or delta-9-tetrahydrocannabinol, refers to the time it takes for half of the THC in the body to be metabolized. This process is crucial for predicting how long THC can be detected in urine or blood tests.
What Factors Influence the Half-Life of Cannabis?
THC Half-Life in Urine
In general, THC has a longer half-life in urine, averaging between 5 to 15 days after ingestion. However, factors like metabolism rate, amount consumed, and individual physiology can significantly influence this timeline.

THC Half-Life in Blood
In contrast, THC typically has a shorter half-life in blood, ranging from 1 to 5 days after the last ingestion. The body breaks down THC more rapidly in the bloodstream compared to the urinary system.
Conclusion
Knowing the half-life of THC in both urine and blood is vital for those under the influence of cannabis, as well as those subject to drug testing. Factors beyond THC metabolism, such as body size and frequency of use, also play a significant role in the detectability of THC in body fluids.
