I wouldn't say we are designed to want more heroin, but that heroin is designed to make us want more...

If you think about it, we crave love even when we've never had it and don't understand it all that well. Nobody craves heroin until they've tried it.

Ahh, but books, tv, and movies are the pushers of love. If heroin were as high profile and esteemed in most societies as this love thing, then yeah, we'd probably all want it even before we'd had it.
