Will I be able to pass my drug test?

So here is my scenario. I am an avid smoker, i smoke marijuana 2-3 times a day everyday. I smoked yesterday and have a drug test tomorrow. I have been drinking water and taking water purification pills(iodine) all day. I was wondering if i continue this routine tomorrow morning and the rest of the night, will i be able to pass my test. I heard that the pills and all the water help dilute the urine so the thc metabolites wont show up. Also if this will work should i do anything to help so it doesnt look so diluted?
