drug screen

Hello!

I was offered a job with Summit Health, in Northern California. I am moving in 10 days! Upon my arrival, I have to do a drug test. Now, comming from Canada, we don't have those kinds of test as part of employee selections...so I have a few questions.

What kind of testing will they do? Blood? Urine? Hair?
I don't have anything to hide because I don't do drugs, however, I was exposed to second hand marijuana smoke several times out of my control (concerts...)

So if someone could tell what type of test is done, that would be greatly appriciated and would relieve some tension. Thank you.
