What is a Cannabis Hair Follicle Test?
A cannabis hair follicle test is a common method used to detect the presence of cannabis in a person's system. Unlike urine or saliva tests, this type of test analyzes hair samples from the head or body to provide a longer window of detection, often up to 90 days.
How Long Does Cannabis Stay in Your Hair?
The detection time for cannabis in hair follicle tests can vary depending on several factors, including the amount of cannabis used, the frequency of use, and individual metabolism. Generally, cannabis can be detected in hair for up to 90 days after the last use.
What Affects Detection Time?
Amount of cannabis used: Higher doses can lead to longer detection times.
Frequency of use: Regular users may have detectable levels in their hair for extended periods.
Metabolism: How quickly your body processes cannabis can influence detection times.
Understanding Test Results
It's important to understand that a positive test result does not necessarily mean the person was under the influence of cannabis at the time of the test. It simply indicates that cannabis was present in their system at some point within the detection window.
