Although I think its bullshit that anywhere tests ya for weed anyway, as if havin a chong outta work is gonna effect ya work.
Even chaz aint gonna effect ya work so long as ya aint at it 24/7
In fact only way your work could be really badly effected by drugs was if ya was a raving bag/rock head and their all too busy robbin their grans to bother goin for an interview :S
