Does anyone know if aspirin works as a screen on urine tests?

urine test is for Thc

No - aspirin will not work. If you are an infrequent user of THC then the drug typically will not show in your urine three days after your last use. If you are a frequent user than things may be more complicated. Residual THC is stored in the fat cells of the body, so your weight may also play a roll. Thinner folks (less fat) don't have as many "hiding places" for the chemical to stay around. Ibuprofen in larger doses has been known to cause false-positive results, so you could always claim that you have a chronic Advil habit.

PS - You may want to ignore the advice of the previous writer to "drink plenty of water." Smart test labs test your urine for a chemical called creatinine. This level becomes abnormally low if you consume large amounts of water prior to the test. This abnormally low level is reported to employers and may "indicate" your guilt (and stand up in court) even if the THC results are negative.

no aspirin does not count, just narcotics.

no, but niacin will clean you out, you can buy it at walmart. take 10 pills 3-4 hours before your test drink at least 44oz of water and pee 2-3 times before your test. The niacin may make your skin turn a little red and feel slight discomfort but it will work

It doesn't. If it did, so many people wouldn't get caught. Believe me, plenty of THC carriers take asprin.

No...water is best. piss5 times before the test in the same 2 hours.

eat lots of popyseed roles and seseme seed roles that will help. you can get the seeds at any grocerystore
