Ok, first the job is in medicine. I will avoid specifics to avoid lurkers as I live in conservative southern state. The test will be on Feb 25. I was told it was a drug screen and have yet to hear back from a friend (non-user) about if it's a UA or hair test. The last time I smoked was the 23rd of Janurary (1.23.11 and last time I smoked was 2/25/11). I have a month before the test. I was a heavy users smoking about a bowl a day. I'm 155 lbs and have a relatively fast metabolism. I also wear my hair about an inch long or shorter (I can cut if I need to). I know with exercise and abstinence from smoking I can pee clean in a month. I will home-test the week before to decide if I need to sub (Which raises more questions since there is a physical involved). SO... with a month clean and exercising, what are my chances? Should I purchase the zydot ultra clean shampoo and use it the day of? Any other advice? Thanks, and it's funny that I can get to this level with a doctorate treating patients and still be subjected to drug testing to see if I'm a scourge on society? What I do in my home after work has no bearing on how I perform on the job.
