Is It Posible for the Drug Ice Not to Show Positive in a Urine Analysis if Used on a Regular Basis?

I was told that some people who used the drug ice took a urine analysis and the drug didn’t show positive. Is that posible?
First off, I’m not the user. Second, I too have a hard time believing that this is true. I can’t help but be curious as to whether it is posible for it to show as something other than meth or these people are just full of crap
