Roofies are real, rapist have been using them for ages. They do not cause sterilisation though. AFAIK it's the same drug as a 'Mickey'.
Once back in my drinking days, I got a spiked drink. I'm a rather large guy of mostly Irish heritage, I had an extreme tolerance to alcohol. One day drinking at a bar, a girl offers me a mixed drink that she says she doesn't want. She said someone bought it for her and she didn't want it. Not being one to turn down a free drink, down it went. The next several hours are blank. Like IMMEDIATELY after, blank. I NEVER - EVER got black outs drinking. This is the one and only time. All I know is a few hours later I find myself driving around aimlessly ~30 miles away. When whatever it was' effects wore off, it wore off quick. By no means was I drunk, it was something else. Scary stuff. Some guy probably wanted to rape her, and she didn't trust the drink so she passed it on to me. :pissed:
The moral of this story? Don't accept a drink from ANYONE you don't know. Thank God I didn't run anyone over with my car, I would be in prison because someone else spiked the drink. Better yet, drink coffee instead:-D
