There are drug kits that can test hair on the spot but I believe is only 80% accurate.

However, drug testing should be done as it is in drug court (I know from experience). They have a baliff watch you pee in the cup and the kit they use is ones supplied to hospitals and/or correctional facilites. I have never seen one person beat one of those even when I personally watched someone use a urine cleaning kit, drink cranberry juice, and urinate as much as possible leading up to their court case. Still came back positive.

Another idea using drug court ideas is to have repeat offenders get their blood tested.

That's how we do it in the military. The unlucky guy assigned to be the watcher, we call that job "dick watch".

A few years ago, we had some guys that had friends in the civilian company that actually tests the piss that goes to them. They got away with getting high for quite a while like that, but when caught, were discharged. I could've done it, but just didn't want to take the chance.
