Longtime readers of MetaEzra know that I'm not one to indulge in sex and booze stories, to say nothing about an English major turned heroin dealer. It's a big world. And Cornell is a big place filled with all types of people, so something like this was bound to happen at some point. Let's just trust that she wasn't the recipient of any of my annual fund gift money. But it does give one pause to ask just who was she selling to. Six ounces of pure heroin yields around 3500 doses of the stuff. And I certainly think that there can't be more than a handful of heroin users among Cornell students. The incidence of use among the general adult population might be around 0.2 percent, so that would be associated with around 40 students users at Cornell and 200 in the Ithaca area. So that might be an upper bound to the Tompkins County heroin market, or so one can hope.
