Heroine's pretty bad, but a lot of people have bad first or second experiences with it and hence don't get addicted. However, regarding its legalisation, it might not be such a bad thing. In Russia, most heroine addicts have spent so much money on heroine that they've had to turn to making krokodil instead, and that's a much, MUCH worse habit, so if addicts could get it through healthcare that would at least help ease the problem...
Personally, even if it was legal I wouldn't try it.
