Dude if you've never been an iv drug user then you really don't understand. Its about compassion and keeping people from spreading HIV and hepatitus.
Yeah needles are cheap and you can buy them almost anywhere in my state, IL, their like $2.51 for 10, but for people without like extra two-fity after buying a dime or two of smack, needle exchanges are a lifesaver. They run needle exchanges in chicago but I'm too lazy to go there and would rather pay the two-fifty for 10 spikes, plus the cops sometimes tail people from those kinda things cause their either carrying or about to score.
Also the people with the needle exchange went around a 100 yard area of Humboldt park in chicago in 95 before the needle exchange opened and found something like 300 syringes. A year after it opened they did it again and found like 35 or something. It's really depressing to think of some poor kid picking up a hype and sticking themselves or a friend and getting aids or hep cause some douche was too stingy to pay an extra, like what a dollar or even less??
Either way you come off as callous with your comments on this stuff you don't even know or really think about.
As far as I'm concerned they should hand out free smack too, the cost of the smack to the gov would totally be offset by the reduction in people in jails for possesion or sale, hardly no one would od with standerdized doses, and the rates of petty theft and robberies would drop significatly. All these things happened in The Netherlands when they had their free heroin expierment.
