I used to be an avid smoker...I'd smoke once a day. I'd been doing that for a while, but I needed to apply for a new job, so now I'm clean. Needless to say, I've been clean for 19 days now. I bought one of the at home drug tests that says 99.9% accurate when I had stopped smoking for 7 days. It showed that I was clean. I'm very lean and a very healthy person. I'm wondering if that test would be accurate as opposed to the ones that they do for pre-employment at places like Lab Corb. I took a test there on Wed. this week. I'm assuming that it would show clean as well but I just wanted to see if anyone else has any experience with this. I'm not smoking anymore, so please no rude or negative comments. I would just like to know if you think I'm good to go. I don't do anything else as far as drugs are concerned. I'm 115 lbs and in great health. Thanks.
