From the looks of Samantha I think we can rule out 'rape' as a motive.. because drugs cost money, it makes no sense that someone would put them in someone elses drink unless they had a motive or stood to gain something...
My theory is as follows: Samantha was a filthy little slut, and she opened that metal filled mouth of hers and gobbled a little too much of the older boys cocks... she was also a coke user, because she didn't feel her parents loved her, and because she watched too much Teletubbies (read the poems section for interesting bits of nothing about her worthless existance) .. well, she was at one of those "rave parties" (though she told her mom she was going to her friend "Katies" over-night sleep over) ... of course given that this was a "rave party", she was required to be under the influance of one or more controlled substances (the Rave Law of 1996 mandated this) .. having spent all her money on Midori and Black and Milds, she went to the rave broke (she told her mother that she spent this extra cash was to "pay a friends way into the movies" - cf:
http://www.ghbkills.com/samanthareid.htm) .. well, in exchange for oral pleasures and a case of herpes, a DJ (DJ MadPhatJungleBreakZ) offered her some "Georgia Home Boy!!!!!!!!!!!!!!!!!" (the multiple exclaimation points and lame 'street name' no one actually uses courtsey
http://www.ghbkills.com/whatisghb.htm) .. she took her cap and ran off, only later to gank the entire bottle when DJ MadPhatJungleBreakZ went to grab another record ("Rock the funky beats") .. one of her friends told her parents "yeah, someone put some in her mountin dew" for some unknown reason...
Look at this, or as the BlackPhreeX would say "peep this y0" -
