What is the typical detection time for ketamine in a urine drug screen?

The typical detection time for ketamine in a urine drug screen is generally about 1-3 days. This timeframe reflects the metabolic processing of the drug and its excretion through urine. After administration, ketamine is metabolized into various metabolites that can be detected in urine tests. The 1-3 days window captures the most common scenario following typical use, making it the most appropriate answer.

In contrast, other options specify either immediate detection, which is not applicable as drug screens do not provide instant results, or longer windows like 1-5 days or 7 days, which are not standard for ketamine. Drugs that have longer detection periods are often those that persist in the body due to slower metabolism or larger volumes of distribution, but ketamine does not fall into that category under typical circumstances.
