Passing a drug test for methamphetamines can be a concern for many, but it's important to prioritize health and safety. Meth typically stays in the system for 1-4 days after use, but this can vary based on several factors like metabolism and frequency of use. Some choose to stay hydrated and avoid drug use to help clear their system. Are you facing this situation personally, or are you asking for someone else? It's crucial to consider the implications and support needed in such scenarios.
