Drink a 8oz glass of olive oil. Cake as much oregano under both armpits as possible.
Drink another 8oz glass of tomato juice. Eat 4 cloves of garlic. After an hour remove the oregano and replace with Allspice. wait 20 min. then shower with cold water.
Chew (not eat) on two sticks of cinnamon.
if this is a pee test you eat pectin the stuff used for canning. the morning of the test. works on pee test only. google erowid for more details on how to do it and yes it works.
@Aster – Well, the reason for the shower. If you can get down 8oz of olive oil and the tomato juice. And make it an hour and 20 min. You would have shit yourself by then and puked on the family dog.
It used to be a brand name of a jar of stuff you buy, just for passing drug tests. I havent had to use it since 2006. You drink it and I took some pill supplements as well to help ensure.
I just googled drug vales and found it and synthetic pee with warmer as well..
Flax seed is also good, I just found. There are ways of winning.
