To anengineer,
Yes there are technologies that can be implemented to stop any user (pilot, driver, machine operator) from using any item by means of a breath test.
In Europe much work has been done on hard wiring breath test machines in to cars, but they are all too flawed.
The technology cannot differentiate between alcohol on your breath from a "night before"' session, and the mouthwash you've just used.
An for the more lateral thinkers, you can always get someone else to blow in a tube. That is unless you want an officer with a special blow-into-my-bag testing all flight crew as they put their socks back on after going through the airport scanner.
