I probably missed out on a sure thing.

I would think more people roofie themselves than use them on others. I got roofied once at a business Christmas party. I didn't realize until I was heading home. Long story short. I missed my stop on the bus, had to walk a mile or so and nearly got hit by a car.

True Story, people roofie people to make them pass out at business events that involve heavy drinking. All those years playing 10 Guy come in handy later in life.......
