Alright so like summer of 2009 I got really high off of these brownies and I'm talking about beyond stoned. So I went to my d&a program (so dumb I know) like that and I was so high but long story short they though I od'd on something else so they called 911. I got to the hospital and the did a drug test of course. I was clean though. That doesn't make sense though. How the hell did I pass a drug test while high? Does anyone have a clue how this worked?
