Let's Go Get Stoned

Let's Go Get Stoned, Ray Charles

Can someone please explain to me why it's perfectly legal to operate 1000lbs of machinery at 70 miles per hour down the expressway, high off cold medicine that makes you feel like adrenaline is coursing through your veins at lightning speed while simultaneously having an out-of-body experience, but I can't buy a bag of marijuana without being arrested?

Shit's fucked. But then, we already knew that.
