The Science of THC Absorption in the Body

The science of THC absorption in the body plays a crucial role in understanding how long weed stays in the system. When marijuana is consumed, THC is absorbed into various body tissues and organs, including the brain, heart, and fat cells. This absorption occurs due to the presence of cannabinoids, chemical compounds found in marijuana that interact with the body’s endocannabinoid system.

Once THC is absorbed into the body, it undergoes a process of metabolism. The liver plays a significant role in metabolizing THC into different compounds, including 11-hydroxy-THC and carboxy-THC. These metabolites are then stored in body fat. Approximately 65% of cannabis is excreted through feces, while about 20% leaves the body through urine. The remaining THC and metabolites are stored in the body’s fat cells.

Over time, THC that is stored in body tissues is released back into the bloodstream. This occurs when fat cells are broken down for energy. Once in the bloodstream, THC is eventually metabolized by the liver and eliminated from the body through urine and feces. However, in chronic marijuana users, THC can build up in fatty tissues faster than it can be eliminated, leading to a longer detection window for drug tests.

The level of THC in the body, also known as THC levels, can fluctuate depending on factors such as the frequency and quantity of marijuana use. Regular users may have higher THC levels in their system compared to occasional users. Additionally, factors such as metabolism, body mass index (BMI), and overall health can influence how THC is absorbed, metabolized, and eliminated from the body.

Understanding the science of THC absorption and metabolism is crucial when considering how long weed stays in the body. This knowledge can help individuals make informed decisions about their marijuana consumption and navigate drug tests effectively.
