I noticed in her biggest song, "I Will Always Love You", that her voice was was already starting to get really raspy and instead of hitting any of the high notes, she went into falsetto. I told my wife that she was either trying to throw some Etta James in her delivery, or she's smoking something. She admitted a few years back she started using coke when she was recording and shooting The Bodyguard. I was somewhat perplexed at the time that anyone could possibly like her version of that song because she was so raspy and struggling so much just to get the falsetto notes. I'm not great at spotting a drug problem, I just loved her voice in the mid 80's and was shocked at how bad she sounded in Bodyguard, but everyone was saying how great she was.
