I think that they work fine for catching drunks, but maybe they simply aren't needed for other drugs. If you're driving is terrible enough, it shouldn't matter if you were on a drug, or over-tired, or texting when you should have been watching the road. If you're screwing up behind the wheel and the cops don't think you're safe to drive you should get a ticket and be driven home or arrested (depending on the circumstances). I'm all for pulling dangerous drives off the roads, but it seems like a lot of people busted for DUI aren't pulled over because they were clearly a danger to others. They were pulled over for something like broken tail lights/headlights or outdated tags and only then do officers "smell" something or think someone's eyes are "red". I don't know if it's just harassment, power-tripping, or if police have quotas to meet, but it sometimes seems like once they have people pulled over, not matter the reason, they will look for any excuse to make an arrest.
