How does a drug wear off from your body?
In: 0
2 main processes can be at work; excretion and metabolism.
Excretion means the substance is removed from the body unchanged in some way. For example, alcohol can travel to the lungs and be exhaled. This is the basis of the breath test.
Substances can also be changed to different ones through a variety of chemical processes. For example, the liver can convert alcohol into acetaldehyde, a completely different chemical.
These processes can be combined, or used standalone. So a drug can be changed into a different chemical, and then excreted through the urine, feces, etc.
