Just to put in perspective, that is enough to supply 12-14 friendly clients with a month's worth of personal stash while paying for your own. Depending upon the volume discount
Charon, you should be a weed-defense lawyer

But seriously, no matter how it's rationalized, it's a lot of weed - and a 1/4 pound is no baggie - it's a BRICK.
It's mid level dealer tonnage... ie: a dealer that sells to OTHER dealers and never sees end users.
Most street dealers buy (more accurately get "fronted") an ounce at a time - and most end users buy a GRAM at a time (1/28th of an oz). A gram will get you plenty baked for an evening. Most drug users do not buy a month's supply at a time. Hell most don't look past the next 20 mins.
ie: she had enough stuff on her to make 400+ people go to Dairy Queen asking for triple cheeseburgers with sprinkle-butterfinger-blizzards.
So I have my doubts... if she was so smalltime and innocent, how did she even show up on anyone's radar (not once, but twice)? And why was she used on such a high profile/dangerous sting ?
The story that she was some innocent kid strung-along by the police doesn't add up in my mind - of course, I don't know the facts either - all I have to go on is that link... I'd like to know more is what I'm saying.
