When alcohol enters your body, it must pass through the liver in order to be metabolized. Therefore, one or two beverages will leave your system long before a six-pack or more will. Because of this, if you know or suspect that an alcohol test may be coming up, it is best to abstain from drinking for one to two days before the test to ensure the best results and chances of passing. The average, healthy liver can process about one ounce of alcohol, or approximately one drink, per hour. Also, all alcohols are the same as far as your liver and the tests go. One beer is one shot is one glass of wine is one mixed spirit.

In order to know as for how long does cocaine stay in the urine one must undergo a urine test for cocaine which detects the slightest presence of cocaine in the urine. In fact the urine drug test detection times depends on the mode of intake of the drug. In case of snorting cocaine, it can be detected within 4-10 hours. In other cases such as cocaine injection, one can detect cocaine compounds in the urine even after 20 hours of intake. The metabolites of cocaine that can be detected in urine even after 60 hours of cocaine intake or its intake for a prolonged period are Benzoylecgonine, coca ethylene (in case of cocaine intake with alcohol) and ecgonine methyl ester.
The procedure of a urine drug test commences from the point when a person ready to undergo the test is instructed to move to a collection site. Then the person's urine is collected in a secure cup which is exclusively meant for the collection of urine. It is sealed with a tape that is tamper resistant and sent to a testing lab for a drug screening. Using advanced scientific methods such as GC-MS methodology, one detects the presence of cocaine in the urine sample. However it is not possible to locate the exact time of & the amount of cocaine intake through this method. Yet this test is relied on for the accuracy of the results that can be sought with the help of standard testing kits in the labs. It is also relatively cheaper than the other drug testing methods.
