To pass a drug test using home remedies, first identify the type of drug test, then try the home remedies recommended to pass that particular test. For urine and blood drug tests, taking water, diuretics, fiber, B-complex vitamins and exercise may help. In the case of hair drug tests, home remedies include Rosemary shampoo, vinegar, sea salt, lemon juice and baking soda. Use aspirin, mouthwash or red meat to pass a saliva test.
Some drug tests attempt to measure the presence or absence of THC metabolites in the body. The metabolites are fat soluble, and urination rids them from the body. Taking lots of water a few hours, preferably 24 hours, before a urine or blood test increases urination, and dilutes THC metabolites to non-detectable levels. Diuretics such as cranberry juice, apple cider vinegar, grape juice and coffee also cause frequent urination.
Exercise helps burn fats, reducing THC metabolites. It, however, requires adequate time before the test to be efficient. Taking lots of fiber aids in passing the metabolites in the stool. To maintain urine integrity, consume creatine 48 to 72 hours before the test. Use 100 mg of B-complex multivitamin two hours to the test to restore the yellow color of urine.
Washing the hair with a mixture of water and lime juice removes metabolites and detoxifies the strands. When using vinegar, use it to rinse the hair and wash with salicylic acid to eliminate toxins and dirt before cleansing with a detergent. The best way to escape a hair test is to shave the hair. Gargling toxin-clearing mouthwash for 30 minutes or taking aspirin a few hours before a saliva test helps disguise the use of drugs. Red meat increases body creatinine levels.
