Cocaine is a helluva drug.
We actually had a guy show up for work yesterday tweeking on something - a middle aged, family man-type, in great shape, a long distance bicyclist (like the MS150k ride), works in Procurement - someone I actually know and like. He came in my office uninvited and plopped down on the couch and started talking a mile a minute about NOTHING... he was slurring, unshaven, dressed like a homeless guy his eyes were red and swollen and he said he had not slept in three days. He was out of work for about three weeks and had just come back mid-week of last week - we were told he was "sick" - and now I am guessing he was at rehab, and that it did not take...
No clue what he was really on, but i guarantee you now that it was not something I ever want to take.
