I Injected Meth On Thursday Night For The First Time

I Injected meth on Thursday night for the first time in months. I am 5'9 175lbs 25 year old male. I drank lots of fluids and even had a smoothie (6 diff types of fruits and veggies) the morning after and took lots of B vitamins like b12 etc. I also took niacin. (I usually do this after using, it makes me feel better physically and emotionally)

On Monday evening I had a random oral drug test. One that they rest on your gums until the dot turns blue. What are my chances of passing this test? And will any of the things that I did prior to test (niacin and b vitamins, etc) help my chances on passing?
