With the crack/heroin/meth angle, my understanding is that you are dealing with a harder criminality at the street level, you're right. I was talking out my ass again.

Just keep in mind that the average user is not buying a quarter pound or more at a time unless they plan on selling some of it to recoup their outlay. Moving from user to dealer puts one in a new category and any ensuing violence cannot be attributed to a "user".
"A nation can survive its fools, and even the ambitious. But it cannot survive treason from within. An enemy at the gates is less formidable, for he is known and carries his banner openly. But the traitor moves amongst those within the gate freely, his sly whispers rustling through all the alleys, heard in the very halls of government itself. For the traitor appears not a traitor; he speaks in accents familiar to his victims, and he wears their face and their arguments, he appeals to the baseness that lies deep in the hearts of all men. He rots the soul of a nation, he works secretly and unknown in the night to undermine the pillars of the city, he infects the body politic so that it can no longer resist. A murder is less to fear"
Cicero Marcus Tullius
