And it came out positive after only three days of not smoking! Haha, who knew right? The cashier at CVS even wished me luck after I bought the test. Looks like I still have work to do so I can apply for some new jobs Oh, and apparently according to the test I took a street name for marijuana is "zig zag". Never heard that one. Or even better, "nose nachos" for cocaine. * I knew I was going to test positive after only three days. I just wanted to take it for shits and giggles. I'll be testing myself again in a week.
