Oh for sure, but it looks like in the US drug tests are found in waaaaaayyyyyy more industries and businesses and likely don't help in any major way, they are more prohibitive than anything. I will say the types of drugs they care about should change more than drug testing itself, obviously you wouldn't want someone addicted to something that could impair their judgement, but things like weed on the weekends or in the evenings is not going to effect any judgement.
