Maybe you have more free time, hon. But that was an exellent explanation of how drugs are classified... er scheduled.
One thing. Heroine actually does have analgesic properties. However, it's so highly addictive and has such serious side effects it's almost never used. It is, after all, almost the same thing as morphine, just not as refined, right? Or anyway, that's what I've always understood.
Hugs and lots of love,
