Personally, i would'nt employ anyone who does drugs, and please spare me with the ''ITS ONLY A SOCIAL DRUG'' drug users are a liability no matter what the job is, you might well pass the urine sample after being given advice, but you will be ''CAUGHT OUT'' sooner rather then later, due to the fact that ''ALL COMPANIES'' operate ''RANDOM'' drug testing, and if you are a regular user or even a weekend/social user someone will notice you at work {after all users stand out like a sore thumb} and tip the boss off who will get you randomlly testered, then when you fail, you will be sacked and near on unemployable as it will be on your employment record.
Sorry for sounding so harsh but as i said, i have ''NO TIME'' for drug users
