How do you pass a drug test without the use of money?

From personal experience, you need to drink no less than 10 glasses of water back to back until your piss is clear. Do this 2 hours before your drug test. but after the 10 glasses you need to keep drinking water and only itll hurt but itll be worth it when you pass. It wont work for coke tho. only weed, extasy, meth, but coke and prescription pills it wont work. this wont get it out of your system but will will trick the drug test to think your clean.

And if its cotton swab, get sum chewable vitiam c and vitiam d and chew it up and spread it around your gums, teeth, and inside your cheeks. leave it in for a good 10 min after that rinse with mouth wash with the alchol in it. don't get alchol free, you need the alcohol to kill the chemicals. and after you rinse, repeat about 2 more times and you'll be straight. do it 2 or 3 hours before your test. if you don't have any money just steal the vitaims from cvs or Walmart, keep going if they try to stop you because they cant legally touch you.
