Urinalysis checks for 31 different metabolites caused by marijuana, 4 caused by cocaine, 3 caused by opiates, 1 caused by Phencyclidine, and 5 caused by amphetamines. Be careful not to over-hydrate.

Try also to pee several times in the morning before taking the drug test. Your pee will contain more metabolites if you haven’t already gone to the bathroom before you take the test. Be smart and chug some water first thing when you wake up the day of the test.

Take about 250 mg of zinc sulfate the night before your test. Avoid eating too many solids. Then, the morning of your test, take the same dose of zinc sulfates. Do not take any more than this if you choose to use zinc. Over-medicating with zinc can lead to harmful mineral deficiencies and should be avoided.
If you have long fingernails, try hiding a small amount of bleached laundry detergent crystals underneath them. Then, when it comes time to take the test, add the detergent crystals to the pee sample and be sure to mix well. This may buy you enough time to take the test again another time when you’re more prepared.
