I've been looking at the Chacon story over breakfast. I don't know how familiar you are with the drug scene, but the quantity involved in this case is significant. He was caught with over an ounce so he's likely not just a dealer, his customers were almost certainly lower level dealers. I've also seen comments that since he was a dealer he probably didn't use it himself. That's almost certainly not true. The 1.3 grams found at his home was probably his personal supply and probably received as payment for his part in the transaction (delivery and collecting money). For him to have escaped detection by urinalysis for very long would call into question the person who runs the testing program at TA-55. If he is giving people advance warning of upcoming drug tests a cocaine user could probably pass urinalysis for his entire career. Even without warning, if there is no observer during specimen collection the person being tested can cheat and avoid detection. Given the lax policy at TA-55 regarding detection of contamination uptake (self-administered nasal swabs), it wouldn't surprise me to hear that they have no observers during specimen collection. Garbage in, garbage out.
