The split test doesn't really matter unless it shows up dirty on the first sample. They will have to send that second sample for further testing if the first sample doesn't pass. I would love to tell you yes you will be ok, but I'd be lying to you. I will say that more than likely you should be ok, but I've been dirty for two months now because I was also a daily toker. I'm 5'6" 160 pds, but I don't eat much and I know my metabolism is slow, so that is why it is taking so long to get out of my system. Just remember not to go and kill yourself if it comes back dirty because maybe that is God(or whoever and whatever you believe in) saying that this job isn't for you. You might get a better job down the road so keep you head up.
