I'm literally speechless that someone here has openly admitted (on a VERY public message board) to snorting coke!!! Dear God! And it's OK, as long as you only do it like once a week or so????
I'm just baffled as to why you'd snort coke, and why you'd admit it on a public message board. Your photo is posted in your profile, along with your personal information like where you work. Could you imagine your employer finding out that you snort coke??? I'm sure they'd love to know that you showed up at work the next day after snorting cocaine. Nice.
If you go to work after snorting coke...there is an issue. I've done it on a Friday or Sat night and by Monday was perfectly fine to work. I'd be more concerned with people showing up hungover as alcohol's residual effects last a bit longer. Aside from that...it's not my employer's place to say what I do in my free time, as long as it's not encroaching on my performance with them. If cocaine is affecting your performance at work, then you should be disciplined.
