I drive Truck for a living,turn a wrench on weekends,but reading about masking agents reminded me about a UA I took last summer.I was in Omaha at a set of lights with 3 lanes 2 going to the left 3rd going to the right.I was in the middle lane going to the left,as I made my turn I heard a screeching and then a loud thump.The second car in the right turn lane decided to go left and ended up under my trailer.As with all accidents I had to take a UA, I ended up staying at the Hospital for like 7 hours because my first 3 tests had too much water.Which they considered a masking agent,by flooding my body with water I was trying to hide drug use.I finally asked them to do a blood draw out of pocket so as to get cleared.Thankfully I took pictures as the Gals lawyer brought up the fact that I failed the first 3 test by being water logged.102 degrees and cant drink water.
