Mouth swabs are a more reasonably analog to breathalyzers for cannabis, although even with those the detection period can be up to 48-72 hours. But still, much better than the months long detection period for the more common urine tests.

My hope is once its legalized fully, more effort can be put into researching and designing more sensitive tests until we have something that is equally as capable as breathalyzers are(which is questionable in and of itself, but I'll settle for equal treatment under the law for now rather than aiming for perfection).
