Interesting times!
It's a boon for LE. They'll have access to the data. If they make enough fuss, they might even get Uber to encourage drivers to report suspicious activity. (What do they have to lose? No one wants to stick up for evil drug dealers.)
Remember how some of the Silk Road vendors were caught. LE found a couple suspicious packages confirmed to contain unlicensed medicines (supposedly via random inspection, but could have been secret spying, or regular gumshoe work). Investigators go to originating USPS office, look for suspicious activity. Quickly find it, make a bust.
Really, it should just point out the silliness of such contraband laws in the first place.

The police, now having the drugs and the guy that was going to send them, hatch a plan. First, they mail the drugs to the coach. Then shortly after the envelope arrives they search the coach's room. Low and behold they find cocaine and the coach is arrested.
I'm not sure how it turned out but it looks like the coach is still coaching to this day:
