How long can THC potentially remain in the body after use?

Up to 5 days
Up to 15 days
Up to 30 days
Up to 60 days

The correct answer is: Up to 30 days

THC, or tetrahydrocannabinol, is the primary psychoactive component of cannabis. The duration that THC can remain detectable in the body largely depends on various factors, including the frequency of use, individual metabolism, body fat percentage, and the method of testing. In frequent users, THC can be stored in the body’s fat cells and released back into the bloodstream over time, which can extend the detection window significantly. While occasional users might have THC detectable for a shorter duration, it is commonly recognized that in regular users, THC can indeed be present in the body for up to 30 days or even longer as it slowly metabolizes. Given this understanding, the option indicating that THC can remain in the body for up to 30 days accurately reflects the potential for extended detection, especially in those who use cannabis regularly.
