Based on information from their own website (see the final paragraph, below), the answer is YES! --- with about 99.9% certainty.
The larger the company, the more likely they are to drug test, since setting up a drug testing program is a bit pricey, but once it's set up, the cost per person drops dramatically. (It like when someone orders business cards: the first 100 might cost $20, but if you order 1000 cards, it might cost only $40.)
Almost every business is, or will soon be, drug testing prospective employees. Their thinking is basically: "Why not? We don't want these folks working for us, since they do poorer quality work, take more unscheduled time off, and increase our risk and liability exposure." The only downside is the cost of testing, perhaps as much as $75-100 per applicant ---- and that's nothing compared to the benefits a company obtains by drug testing. It's like cheap insurance, so that even if a bad incident occurs, the company can truthfully state that they did all they could to proactively protect the public ----- what will they say if they FAILED to drug test an employee who later causes something bad to happen? ("We were just trying to save that $75" won't sound too good when the guy from "60 Minutes" wants you to explain to America why that gate in front of the nuclear reactor wasn't secured.)
The bottom line: if you're looking to work at ANY job, plan on being drug tested. And remember this ---- those kits sold at some pharmacies that claim to produce a clean urine test are total BS ..... and the newer drug tests even check for a couple of ingredients that these kits contain [these are not illegal substances, but they are substances that people don't usually have in his/her urine. So the drug tester knows that the applicant is trying to disguise some illegal drug, as well as making a pre-meditated,deliberate attempt to deceive his/her prospective employer].
How do I know this? --- I'm in the medical field, and I am often asked to review questionable drug testing results (for both military and civilian testing programs).
