A misleading nickname for GHB, only describing what it can do to total dumbasses who get hold of it. Unfortunately, after seeing the substance referred to as a "date rape drug" in ER, those same idiots end up killing unsuspecting innocent people too.
You see, GHB is fairly nontoxic by itself, but lethal when mixed with alcohol. Thanks a lot to the sensation-hungry media for advertising it to the masses as a great date rape helper.

Because of the aforementioned dimwits, GHB is getting banned all around the world. The legal stubstitute 1,4-butanediol is said to possible cause "grievous bodily harm" even when used responsibly, and is even more lethal with booze.

Isn't it ironic? Don't you think?
