You've had a job, haven't you? Of course you have. Most likely you've had a job requiring a pre-employment drug screening. Equally likely that job did not require post employment, suspicionless drug tests. Almost as if a drug free workplace is a one day event, with that day coming before you're actually at the workplace. Afterwards nobody cares, so...toke up.
It is the same as politicians. They come out to press the flesh before the election, with feigned sincerity they do their best to fool you into voting for them. Afterwards they really couldn't care less about any of that, any of you. Sure, they may have these "public input" online push polls gathering "data" you'll never see, just so they can say they're still "in touch." Hardly.
Want proof? You need look no further than city hall. Do you think those nattering nabobs have a clue about your issues...your concerns? Only if you're as clueless as they are. Are you?
