If you have no time and are going to get a drug test really soon this is an option. You can dilute your urine sample yourself, when receiving the drug test. You add warm water to the urine sample and this reduces the concentration of drug or drug metabolites in your urine sample. It's also said that green tea is an excellent dilution drink. This method is not likely to work most of the time. Most places now put you in a room without a sink in it. The drug testing laboratories often will test the sample for dilution. This drug test tip is kind of an emergency option.
Flushing out your body is probably your best option when passing a drug test. You must have a few days before the drug test before you try this method. Try drinking a lot of water each day and continue urinating to flush the toxins out. Eat vitamins also as they will help remove drug metabolites. Never overdue the water drinking. Some people die of water intoxication. You also have the risk of colorless urine when receiving the drug test. This alerts tehm that you are diluting your urine.
Overall your best option for passing a drug test is the substitution method. This means you are going to use another person's urine or a synthetic sample. If you have multiple drug tests and are willing to spend some money on it, the whizzinator, is one of the best products out there. The makers are currently being sued over their product, but many places are still selling them or similar products. There are a few different kinds, but they keep your urine at the appropriate temperature and firmly on your body. I'd recommend getting a product like this is you take a lot of drug test. These drug test kits are almost full proof and will work pretty much all the time. So, I would definitely agree that buying a drug test kit like that is the best option. Buying synthetic urine is also a pretty good option that I would recommend trying also if you don't have much money.
