No respect whatsoever for anyone who drives under the influence, no matter the reason and then dismisses it or does it again. It's asking for trouble. If it was only for yourself I couldn't give a fuck, but it's not reality. When you drive a car you have your life, the life of your passengers, the life of other people on the road in vehicles or on foot in your hand. I can understand someone slightly under the influence going for it, I don't respect it more but I understand that sometimes you don't really understand you're under the influence until you're put in a situation where your reflexes have to be top notch.
But OP was high to the point where you thought you were roofied. That's being beyond fucked.
Hope OP actually learns from this, and doesn't dimiss it as a honest mistake, or a fun story to tell people down the road since nothing bad happened. This is something that should be a life changing experience for anyone with a conscience. A good person will learn from it, understand how lucky they are that they killed no one. A selfish person will only be glad they didn't get caught. A really bad person will do it again.
