Well said matt. Funny how the aviation industry is singled out here. If i have a beer after work and get breath tested (Tests run 24/7) and blow over .02, i obviously have a drinking problem or an intention to fly/taxi/conduct maintenance on an aircraft, and therefore am compromising the safety of an operation. We all know how small an industry we are in, and that in the extremely rare event someone has a drug addiction or becomes an alcoholic, their employer is among the first to know and the individual will be dealt with accordingly. This will only serve to deter more people from becoming a pilot/engineer/ATC. Anyone read 1984 or Brave new world lately?
