I may have done something very stupid. Please help me figure out some peace of mind :(

I am a performer and recently auditioned for a very large theme park and...got a callback for a role! I don't feel comfortable letting the internet know my location, but know that this is a large and famous theme park that provides tourism money for a smallish town. Now the bad news:

This theme park requires all applicants to submit a drug test. Because it is a hair test there was pretty much no way for me to prepare my body within a few days' notice. I bit the bullet and went ahead with the test. I just got a call from the company that completes the test for the theme park and they said (of course) I tested positive for marijuana. They asked when was the last time I used and I said about a month ago (I panicked and lied--it was actually about 2 days before the test). They said they would forward the results to my potential employer who would then decide what to do.

Basically now I'm sitting here completely stressed out that they will contact authorities and my young life will be ruined because I wanted a performing job so bad I took a stupid drug test after knowing I would test positive. Someone please tell me what the company can legally do: can they contact police? can they turn me in? will this totally fuck up my life? I'm really panicked right now.

Additional info:

* This job would be for performance that does not involve operating any sort of machinery or partnering with someone else (so no danger of them saying, she gets high so she'll fuck up and hurt someone).

* I'm over 18, so no worry of contacting family\parents (I don't think?)

* The person who talked to me did not say I tested positive for anything else, so that's good I suppose--even though in the last 90 days I've dropped acid and taken molly (I thought a hair test picked up everything you've done in the last 90 days)

Sorry this is long and thanks for any\all info!
