Introduction
Understanding how long drugs stay in your system is crucial for a variety of reasons, whether you’re preparing for a drug test, concerned about health risks, or working toward sobriety. The length of time a drug remains detectable depends on multiple factors, including the type of drug, frequency of use, metabolism, and the type of test used (urine, blood, saliva, or hair). This guide provides a comprehensive breakdown of different substances and how long they typically stay in the body.
Factors That Influence Drug Detection Time
Several factors affect how long a drug stays in your system:
- Metabolism: Faster metabolisms process substances more quickly.
- Body Mass and Hydration: Higher body fat may lead to longer retention times, while hydration can impact urine test results.
- Dosage and Frequency: Higher doses and frequent use lead to longer detection windows.
- Type of Test: Different tests detect substances for varying lengths of time.
