How long opiates take to leave urine if taken for a month?

Opiates can typically be detected in urine for 3 to 7 days after use, but this window can extend significantly for chronic users or those who have taken them for an extended period, such as a month. In such cases, opiates may be detectable in urine for up to 30 days or more, depending on factors like metabolism, hydration, and the specific type of opiate used. Individual differences, such as body fat and overall health, can also influence detection times.
