I may be wrong, but I thought we were discussing how many regularly-heroin-using people die early, not how many people try heroin once and subsequently become addicted.
Oh I interpreted the thread to be talking about heroine use in general. Could go either way I guess, there's a lot of comments at this point.
Though ime most users don't die. Which is why I support legalization. What I watched happened with my drug phase and others, it was mostly a phase and people just needed time, support and patience to get through to other side. There might be extreme examples ruining it for all, but I saw a lot of people stop after some serious use.
Unfortunately some die because of the policy we have like a few people I knew personally. All uncessarry.
