Yes, that and other reasons. Quinine used to be over-the-counter in the US; people took it for leg cramps. But they made it Rx-only in the 80s (or 90s; not certain) because it can have dangerous side-effects (including cardiac issues) in some people. It's kind of a nasty drug, but it's better than malaria. There are now better drugs for the conditions Quinine was used for.
