Pre-Employment Drug Test at Walgreens?

I had an interview for Walgreens on tuesday last week and I think it went well because the lady told me to go take a drug test and after she told me to take the drug test and she'll call me. I went on thursday of the same week to take the drug test and it's about to be two weeks since the interview and I still haven't received a call, is this normal? I want to call them but I don't know what to say when I call them. I know I passed the drug test because I don't do any sort of drugs. I feel like I might have not gotten the job, please tell me if this is normal or not
