Furthermore, there has never been a commercial airline accident linked to pilot drug use. Drug tests don't prevent accidents because they don't address the root problems that lead to substance abuse. But good management and counseling can. In this context, the goal is rehabilitation and wellness - not punishment. The argument that if you don't use drugs, you don't have anything to hide, is false and misleading.
Drug testing allows employers to intrude upon the private lives of their employees.
In short, employers need to kick the drug test habit. Louisiana, Maryland, Nebraska, Oregon, and Utah have adopted legislation that regulates drug testing in some fashion.
