I am not sure if that is the correct spelling, ill try to buy some later to find out.

My mom has used this for the past five years and she has never come up positive for marijuana. I don't know if it works for other drugs.

Take it a few hours before you have to be tested 3-4 should work.

You can buy it at most grocery stores. make sure you injest(sp?) the whole box.
