A New Requirement to Receive Welfare?

Today, I heard something very interesting that I'd like to throw out for open discussion. A fellow working up in the Alberta oil sands drives heavy machinery and, as such, must submit a urine sample once a month to prove that he his not taking any drugs. His company takes safety very seriously and anyone on drugs operating such equipment would put countless lives at risk.

So in essence, a requirement for him to be paid every month is to submit to a drug test. He earns well over $100,000 per year, a big portion of which is paid in income tax, which goes toward the services that all Canadians enjoy.

Now let's compare him with someone on welfare. Is not welfare a temporary measure that provides short term funding until a person can find a job again? That's what I always thought it was for. If someone is being paid by the government in this way, then what responsibilities do they have? If their primary objective is to find a job then wouldn't it be fair to say that being high on drugs some or all of the time would not be conducive to getting hired?

That oil sands worker strongly believes that everyone who agrees to receive welfare must also agree to a compulsory drug test. What say you?
