OK, I'll give what info I know. If nothing else, someone who reads this will learn something new.
GHB/roofies/date rape drugs QUICKLY dissolve in liquid. They are colorless, odorless, and tasteless. You don't know you've been hit until usually the next morning where you wake up and can't remember a good chunk of the night before. Other than staying away from places that you KNOW date rape drugs have been showing up,
NEVER allow someone else to get a drink for you. ALWAYS get your own.
NEVER set your drink down or leave it unattended.
NEVER drink from a "community punch" Get your own sealed bottle/can. And open it yourself, or watch the bartender open it.
If you have a beer bottle, keep your thumb over the hole when holding it.
If you can't drink out of a bottle/can, take a mug with a lid on it.
Watch for very "out of it" sisters being led away by one guy away from the crowd. Stay in pairs, etc.
Don't drink!
Of course, this advice applies to both genders. However, I don't know if a guy who takes GHB will be able to *ahem* "function", so I think it's more prevalent that females are hit with GHB then males.
Your college health center or counseling center can also give you information. Of course, this info was probably in the pamphlet they gave you or your sister/daughter/etc. It's basic info.
And by the way. Let the university and police do their job. You never know who's undercover and
*watching*!! Why call attention to yourself, unless you like that sort of thing.
