Hi,
Based on the information you've provided, it is likely that the
THC from the three hits of weed you smoked will be detectable in your system for up to 7 days, potentially longer, depending on your
body fat percentage, overall health, and other factors.
Drinking water and exercising can help to flush out some of the THC, but it may not be enough to eliminate it from your system in time for the
drug test. It's also worth noting that the initial negative-dilute result may have been because you drank a lot of water before the test, which can dilute your urine and make it more difficult to detect drugs.
It's impossible to predict your chances of passing the drug test with certainty. However, based on your information, likely, the THC will still be detectable in your system, and you may test positive for the drug test.
Take care. Hope I have answered your question. Let me know if I can assist you further.
