This home drug test....

Phamatech At Home Drug Tests

I was reading up on these since these are the tests that are at my local supermarket. Do any of you have expierience with this exact type of test or anything like it? Do you have to send-in to get the results or are the results given @ home. From what I read it seems like you only have to send it in if the test comes out "inconclusive". I figured I'd would ask for users who have taken these tests just to be on the safe side. Help would be great.
