i and some friends have passed the test where the cup is the tester one day after smoking by drinking water constantly the day of the test. The theory is that the water dilutes your urine enough so the test wont pick up the thc. however more and more places are using the test where they only use one drop of urine on a testing strip. I have a freind who had passed the cup test with the water method fail the eyedropper test. I dont personally know of anyone beating the eyedropper test while dirty. Ive never done the eyedropper while dirty so cant say. Im currently subject to random testing, so i use the surefire method, i dont smoke, ever. your test is far enough away that u can stop for 30 days and be clean for the test. As an added bonus, ur tolerance will drop and u can get high as a mug after the test on very little weed. btw, are u sure they are doing a drug test, cause u know its not standard during a physical. Have they said they will be doing a drug test? it seems an odd requirement for a college physical, but what do i know.
