Do student-teachers get drug tested?

Hey all - I am a senior in college in Indiana and I'm going to start student teaching on Jan. 4. I use weed and delta-8 frequently to help cope with some anxiety and also just after a long long day. I've looked into my placement school's HR resources and staff handbooks and never found anything about using weed outside of school and not during work hours. (I only use at night). I can't find anything in these handbooks or contracts about student-teachers, much less on drug use for student teachers. Delta-9 (THC) is not recreational in Indiana yet, but Delta-8 is, although I'm pretty sure it would still fail a drug test. I'm just wondering if any student-teachers here have ever gotten drug tested and which states you're in if you did or didn't. Thanks guys!
