What you may or may not realize is drug testing is far from detecting intoxication on the job. Marijuana can stay in your system up to three weeks. So if I decided to smoke some pot on Thanksgiving, and then got drug tested on Monday morning, got positive results when the substance has no impact on my performance or duties, how is that a public safety issue?<quoted text>
Because you have a job (truck driving) where the public safety aspect has been decided to trump your Fourth Amendment protections. This was decided in "Skinner v. Railway Labor Executives Association" in 1989. This was a controversial decision at the time.
"At face value, random drug testing appears to be a violation of the Fourth Amendment, which protects the right of citizens "to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures." In addition, the Fourth Amendment states that "no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized." However, the United States Supreme Court ruled in Skinner that random drug testing is permissible for employees in safety sensitive positions."
To reenforce Pop's point, there is no difference how somebody is financially supported. People on public assistance are living off of taxpayers money, and I would be willing to bet that most taxpayers have no problem with drug testing welfare recipients.
It's not just drug testing either. Do you realize that the DOT can pull me over anytime they desire and search my truck? They look inside of the cab, inside of the trailer, underneath the trailer, underneath the hood, and they don't ask for my consent? They have no warrant or probable cause either.
Okay, so it's all for public safety. Don't you think that a parent using illegal narcotics is a safety issue for their children?
