Well, from an instructors standpoint, who would you like to see perform the drug tests? The agencies? That`s not going to happen. How about having the government regulate the drug testing process? I don`t think you would want any government regulation of anything scuba-related, or do you? I don`t drink nor do I smoke or do any type of illegal substances and maybe I have a blind eye but I don`t see this as an industry-wide epidemic. If you suspect that an instructor is under the influence while conducting scuba operations, contact employer/agency. There are too many dive professionals to test in order to dispose of the relative few that practice this habit. Will the consumer pay for this drug testing program? I just don`t see the problem being large enough to pursue this type of solution.
