[OH] Question about pre-employment alcohol and drug test & secondhand marijuana exposure

Hi all! I’m starting a new job soon and will have a pre-employment drug and alcohol test. I don’t use marijuana or drugs and I don’t smoke.

However, last weekend my ex was smoking marijuana in my car with the window half down while I was driving. Could secondhand exposure cause a positive drug test?

I also drink occasionally (socially). I’ve never been tested for alcohol as part of employment before, and I’m just trying to understand how these tests work and what to expect so I can prepare. Honestly, I'd love to have a glass of champagne or two to celebrate but again, have never heard of an "alcohol" AND drug test.

I live in Ohio and would appreciate any insight. Thanks in advance!
