Need to pass a drug test

Hi everybody. I need opinions. I have a job interview coming up. The last day I smoked was on 7/11 and the interview is on 7/25. So when I have the interview it'll have been two weeks since I've smoked. I'm normally a pretty chronic smoker. I don't smoke every day but it's close. And on the days that I do, it varies between 1 - 3 times in that day. But usually it's just when I get home at the end of the day to fall asleep. I'm a 25 year old white female, I'm 5ft 4in and I weigh 120lbs. Currently I'm drinking tons and tons of water (literally going to the bathroom every half hour), and I'm drinking everyday detox tea. I'm also taking the seven day complete body cleanse from GNC, eating healthy food and doing my best to go for a walk/run everyday. I also bought an at home test for me to take the day before my interview. Now, I don't even know if they would make me take a drug test the same day as the interview. I think it's more likely to be within a week after that but I'm not positive. Will I pass? And is there anything else I should do?

 

Substitution isn't an option. I'd rather decline the drug test and lose the job than get caught trying to fake it.

 

Lol pretty sure I pissed like 20 times today.
