Thanks for your help! I pulled up the policy handbook and an app for the same position I applied to (it was an online app). From reading the policy handbook this institution seems to focus on voluntary confidential rehab and treatment for their employees, and doesn't explicitly mention anything about testing. I found a mention of a Drug Free Workplace in the policy handbook, but all that was included in that section is the following (keep in mind that while I'm not sure if the team I would be working with is working under federal grants, I'm going to work under the assumption that it is):

The federal government requires that each employee directly engaged in the performance of work under a federal grant or contract must (a) be provided with a copy of a statement describing the employer's policy; and (b) be notified that, as a condition of employment on that grant or contract, the employee will abide by the terms of the policy and will notify the employer if he or she is convicted of any criminal drug statute violation in the workplace, no later than five days after such a conviction. All individuals subject to the federal requirements should report to their employer any conviction, and the employer, in turn, is required to notify the awarding federal agencies of any convictions.
The app made no mention of the act or any pre-employment testing, but it did say the standard "I agree to abide by the Institute's policies, rules, and procedures and any changes hereto" line that prompted me to check into the policies of the institution further. The app also included this line:

I also authorize the Institute to conduct any other background checks or investigations, which it deems appropriate and understand that I may be required to complete separate authorization forms for such checks or investigations....I understand that employment is contingent upon the satisfactory completion of various background checks, investigations or examinations and my compliance with other employment requirements, such as proof of eligibility to work in the United States.
I didn't notice any dfwp signs, but it's a huge campus and I wasn't really looking for them.

So did I technically authorize a drug screen, and should I expect to be given one in the near future? With or without any notice? All this legal speak makes my head spin! I just want to know when I can indulge again :jointsmile:. Thanks for being so patient with all of my questions.
