iggydank Reviewed by iggydank on . Pre Employment test tomorrow. Ok.. I'm a long time smoker, but I recently quit.. I hadn't smoked in over 4 months before last week & I smoked about 2 g's or so. I learned today that I will be taking another drug test for work tomorrow as they decided to hire me on early.. I really don't wanna take my chances with flushing so I'm leaning towards just using a substitute.. That bring me to my question.. Do labs check for gender of donor? My gf is clean & willing to provide a specimen for me.. But If they check Rating: 5
