It sound very much like you did the right thing regarding the drug screen. I know it was hard, but the "right" thing to do is often not the "easy" thing to do... so great kudos to you for having the strength and insight to follow through with what you thought was best.

I hope having the support and confirmation of your friends here helps make that decision easier, having people who understand and agree that it was the right thing to do.
