On the other hand, I've never known anybody to use heroin or opiates in general and know very little about these drugs. Reasononline has an article H The surprising truth about heroin and addiction. Unfortunately, I don't trust it, as per my rants below about the lyin', cheatin', media. Especially when they throw the word "truth" in the title. That's almost a guarantee that it's not the truth. Other than that, it's an interesting article.
The main point I'd like to make is that Drug Policy, and the millions of peoples whose lives are affected by it, seems to be based completely on intentional lies and other perversions of the truth. But real data, trustable data, data that could be used objectively to make people better off is nowhere to be found.
