FWIW, "those other bands" and yes, all the other grunge at the time that came out fits under that label (sound garden, pearl jam, mud dauber, butt plug, etc.) didn't sell near as many albums as Nirvana, long BEFORE he got whacked. And he definitely got whacked. The whole thing was super shady. His brother (step brother, nice guy) went to school with my cousin (fucking lame drunk slut), and he seemed naturally upset about it (though they weren't too close, age wise and otherwise), but definitely suspected foul play.
Drugs though, yeah, if you are on the heavy ones (H or meth) then you are likely to get whacked or die by yourself anyway.
I'm more interested in who killed Kennedy though, and whether Bush Sr. was on the grassy knoll that day or not. It IS known that he worked for the CIA, and that he was in Texas that day. Subsequently he was acting president (under the puppet Reagan) and then actual president, before installing his son GW through a faked election as puppet president under Cheney. Too bad Jefferson, and the other architects and didn't have contingencies for this in the Federalist Papers.
But Nirvana was only a so so band. They were much better than those other (comparatively) low selling grunge acts, however.
I look forward to the next "real rock" movement, after all these Limp Bizkit/Lincoln Park boy bands quit selling.
