If it is a place of business and the business wants to drug test for reasons of safety or some other issue, by all means test away.
They should not hire who they feel cannot do the job and do it well.
I just don't think it is anybody's business if someone is drinking or smoking whatever.
Everyone has to live with the consequences of their actions, good or bad.

You've hit it on the head. The people, and that includes FReepers, who are against legalizing drugs are people who want to control others. They are as bad as any liberal when it comes to being a threat to freedom. I don't smoke pot but I am all for legalizing it, and other drugs as well.
The war on drugs has been the one of the main reasons our freedom has eroded away over the last 50 years or so and has accomplished absolutely nothing.
