If we were drunk/high all the time, drink driving laws couldn't be enforced and so there would be soo many legal deaths on the roads... loads and loads of road traffic accidents (RTA.. cop talk is good) would happen and no one could do anything about it, they'd just get "Well as you well know, we're all stoned and drunk so it's not fault I plowed into that crowd of people and killed 100 people, officer." So yeah, it'd be fun, but fucked up!
