The
problem with drugs is that you can't always know when a person is high,
or
when drug use is affecting critical safety skills like judgment or
coordination.

You're probably right about detecting impaired judgment, but physical
coordination can be measured:

Let's see, that wouldn't be a TEST, would it? As in, a TEST to detect
physical impairment? :-)
