Why is it anybody's business but the users if they choose to render themselves unable to get oil patch jobs?

Taxpayers for one - we pay for health care, food stamps, etc. for those unemployed.
And company's for two - they need workers for projects they bid on or hold. It's bad on other employees (who have to take up the slack) and on the company's bottom line when they don't have staff or those with skills to do the job.

We should stop. Using one violation of rights to justify another is not a conservative argument.

They don't own the labor pool; they should meet their needs by either more narrowly tailoring their testing - standard marijuana testing detects any use within the past few weeks - or by raising the wages they offer ... supply-and-demand and all that.
