Companies I know of that do drug testing: - Walmart (1.5 million US employees) - IBM (352,000 US employees) - Target (350,000 US employees) - Kroger (450,000 US employees) - Home Depot (400,000 US employees) These are just spot checks of the top 10 largest employers. Obviously, sectors such as transportation and finance also have broadly embraced drug screens. Based on my experience in IT, they are not outliers. As a contractor, I've even had to submit to drug testing for contract gigs in the past.
