Whats causes 1 to fail a drug test?? HMMMMM??
That's easy.
Using drugs.
I went 12 year with no smoking. 7 years worth incarcerated in Federal Prison, and then 5 years of supervised release. I original had 8.5 SR but got a violation, and got sent back.
Got ratted out by a partner 1st time. I got charged with 1000 clones. Got out, on SR, NO SMOKING ECT... Got ratted out again with another partner, and got sent back to feds, and also had a class c state charge run concurrently to my federal violation.
Bottom line is if you don't want to be a walking target, and you know you are prone to a drug test, be it for a job, or parole/supervised release. Stay clean, at least until you get setteled in at what youre doing. For me, they tested me 2x a week, and sometimes would do a surprise visit for more than a year. Then after that, they gave me enough rope to hang myself, though I did get ratted out. got out in 2009. Did from 1997-2009.
Also with the feds, theres no way to sneak any type of fake urine ect, as you have to go through a body scanner to enter any federal building.
