I passed. I was able to use the synthetic urine but took the drink as a back up I had to use half and half he wanted half a cup and that synthetic urine only has like 2oz in it so I was able to do both... I am a heavy smoker meaning everyday and at least 3 bowls a day not that heavy I guess considering some people but still. I recoment synthetic urine for lab tests and regular urine screens. I had a whole bunch of lab work done today,blood ears eyes everthing so happy I really needed this job.:rasta:
