Something tells me this will not survive a serious court challenge.

I've drawn many chain of custody blood alcohols. I absolutely refuse to draw against a persons will. In fact, I always specifically ask if they are complying of their own free will and understand the implications of their consent.(They are waiving their 4th amendment rights.)

Makes for a much stronger case if you advise people of their rights and make sure they clearly understand their consent.

Of course, most are too drunk to really give "informed" consent. They haven't a clue to the fact they they are handing over incriminating evidence.

Nor should it. Since the penalty for refusal can just as easily be made the same as it is for guilt.
