In regards to the urine tests, they are looking obviously for an all clear but... they test urine for 4 types of drugs...
1. Marajuana (this is fat soluble so for those users I suggest that you give up atlest 6-12months ago as it sits in the fat of your body and slowly dilutes; slowly meaning months/years)
2. Amphetamines
3. MDMA
4. Ice
Not sure if the last 3 go under the same heading, but I do know they test it for those sorts of things, and YES they will watch you so boys don't bother using your g/f's because high levels of estrogen will appear.
