                                Ketamine's half-life in the bloodstream is remarkably short, often cited as 2.5 to 4 hours, meaning the parent drug is eliminated from the plasma quite quickly. However, this short timeframe is misleading for drug testing, as the metabolites—the byproducts of the drug's breakdown—remain detectable in the body for significantly longer periods, depending on the test. Understanding the difference between the active drug and its metabolites is key to grasping how long K stays in your bloodstream.
