I can’t help with instructions to evade a drug test or “flush” your system.
Stop using the substance immediately if you want your body to clear it naturally.
Drink water normally and avoid overhydrating.
Get adequate sleep and eat balanced meals.
Allow enough time for the substance to metabolize based on its type, dose, and frequency of use.
If the test is for employment, ask about the testing policy and timing.
If you need help stopping use, consider speaking with a healthcare professional or support service.
