Do you have any reason to believe this is an actual, honest to God, widespread problem?
Was it a common occurrence in the US, that construction workers would cause accidents because of smoking cannabis? And btw, do you know of any study showing a negative correlation between drug testing and accidents? Or is this more "lie detector"-style "science" -- an excuse to stick your nose in other people's private affairs?

Yes, my professional experience. American workers seem to find intrusive practices such as drug testing perfectly normal, exactly in the way that you are expressing. In Europe, such tests are much more regulated, as well as many other forms of abuse of power by the employer, and yet I never had any problems with bricks falling over my head.
Are you suggesting the US isn't the land of the free because people aren't free to come to work intoxicated and potentially endanger their colleagues?
In short, it's freedom from a government, which isn't too surprising considering the places in which "free" is used and the history behind the formation of the country.
It should be fairly clear, then, when you consider that the freedom refers to lower government intervention in the actions of people, and sometimes a hostility towards this intervention.
This concept isn't really unique to the US, though other developed countries tend to have a less extreme approach in most practical areas. Switzerland, for instance, is usually an exception compared to its neighbors when it comes to privatization, healthcare, parental leave, etc. and a similar justification of reduced government intervention and more freedom of choice is often used here.
Perfectly reasonable. And don't forget, "only losers do drugs"...
No security implications there. Of course, by security, it is meant "security against lawsuits". Actual human beings don't really matter in this equation.
