I said: "Much of the problem with heroin (not necessarily coke) is that people can't afford the habit. They turn to crime and they also sacrifice healthy interests for the sake of their habit. Making the drug cheaper and more available for addicts would arguably ease these problems."
What I meant to say was that the prob with heroin is the cost, while the problem with cocaine is potentially much more health related. See, you can (apparently) have a heroin habit for life with no health problems, as long as you get clean heroin. So the problem is not the health risks of the drug (except for OD risk... granted), but rather the fact that many people cannot financially sustain the habit, and turn to crime. They also get impure heroin which is a health problem.
Cocaine, as far as I know, is much more iffy as far as health effects. It may be that it is a far more costly drug as well. On those matters, you guys seem to know more than I.
I wasn't clear enough in what I was saying. Thanks for calling me on it.
