"Is routine drug testing universally considered acceptable?" In the US, yes. There is a very, very, very good chance that your cashiers, call center workers, and a slew of other low-level (and store management) positions have had to take a pre-employment drug test. A lot of government jobs require it as well (IIRC, the government has some issues getting tech folks because of drug test requirements): Some have to take random drug tests during their employment. It doesn't matter if it will affect your job at all. In some states, they can reject or fire you for nicotine. I don't think this is as acceptable outside of the US: I'm in Norway now, and it would probably be illegal without reason (pilots, for example... perhaps). And a real reason, not just wanting sober employees or to sort potential employees.
