That's not really asymmetrical, in the same way that e.g. wage information is. You can refuse to take their test (and not be hired) the same way they can refuse to take your test (and you refuse to work for them).
That being said, I believe that weed usage not being comparable to alcohol usage outside of the workplace doesn't make sense. I think it only makes sense to test for harder drugs e.g. opiates and amphetamines.
