i have considered this but always feel like i am too nervous and would possibly drop the cap. not that anyone is in the room, but i would hate to have to splash around in the toilet to pull it out. Also, just an observation. My last two drug tests, they were looking for way more volume than the 2 oz. I brought in. Both times the women marked off what i would guess was over 6 oz. I think next time around I will bring a larger sample, 3-4 oz. just to calm my own nerves. Although I am aware that they really cannot ask for more than 2oz, I think a larger sample may help to ward off suspicions if there were any. Any thoughts on why both Quest and LabCorp seem to be looking for larger samples? Are they trying to catch the subs? My past experience was that they don't want anymore than they have to work with, now they want a lot... probably should of started a new thread...
