Was against it from the start and the statistics have proven this is a very cost-ineffective safety program. In fact, so few airline workers (not just pilots) were found to test positive, that alcohol was added just to save some face. Of course the way it is conducted means it is ineffective as well.
Random drug testing should be at the discretion of the employer. Not another costly government mandate.
Airline pilots had a proven program of interdicting crewmembers with problems and getting them straightened out. There is no "drug problem" to worry about in the industry.
