I've been smoking a bowl every weekend for the past month or so when I party on the weekend So one day I get randomly drug tested on a wednesday, and it seems like I passed since they didn't say anything... So to make sure I bought a at home drug test kit from CVS, and pissed in it the next morning right after I woke up, sure thing it came out negative. On that saturday I went to a party and smoked another bowl, and took a few hits from 2 different blunts.. I had this 'dip stick' drug test kit and sunday morning I tested myself and I came out negative again... and to make sure it wasn't a false negative, i tested my self again, and yet I was negative. ?????
