If you are wondering how long can drugs be detected in urine, then you have come to the right place. There are several factors that affect the duration of a drug's detection in urine. These factors include the amount of time the drug is in the system, the type of drug, and the user's metabolism. The duration of a drug's detection in the urine can also depend on the type of test. For example, rapid urine screening tests are fast and can provide results in minutes. However, they may not detect substances that have been diluted. Another important factor that influences the duration of a drug's detection is its half-life. Typically, drugs with a long half-life are detected for longer periods of time. In other words, they take more than a day to completely exit the body.
