contact solution

I heard that if you put contact solution in your urine for a drug test, it will clear any marijuana traces. Is that true? Bc this person smokes weed everyday and he put contact solution in his urine and the test didn't detect any marijuana. But this person that did this, I've never met and I don't know them, he's a friend of a friend. So does contact solution make weed traces disappear? I don't want to spend $40 on detox and I'm not chugging gallons of water for this job...

Okay can anyone answer this question? Just a yes or no is fine. Thanks alot

I'm going to have to lean strongly on the bullshit side.

I have never heard such a thing, so i wouldn't know and suggest anything except Water, Certo...
