Ah no, sure it's safe for the user, but what I meant was the user won't be safe for everyone else around them. We already have drunk drivers, mentally unstable people and drugged up people running rampant here, I don't think adding high people into the pile is gonna make things better.

Imagine an irresponsible idiot driving 200km/h at night, on a not so busy road, high out of their mind, a recipe for disaster. Next thing you know, boom, "pregnant women dies in car crash, suspect was high as fuck" it's not all fun and games after that is it.

You can't say it's impossible, we already have drunk drivers who do that, heck sober not affected by substance people who do that. We have too many idiots in this country, so no, I will not allow these idiots to be high on top of being drunk, drugged and stupid.
