it seems like everybody in that celebrity world did drugs in the late 70's early 80's cocaine was considered the rich mans drug eddie murphy, whitney, rick james, natalie cole, jennifer holiday, james brown, El Debarge, David ruffin, nell carter, river phoenix, john belushi, janis joplin i could go on and on with names of those dead or those who managed to over come, notice most the names mentioned were frequently in the same circles. though it was considered the rich mans drug i always wondered is that why whitney said crack is whack cause it was a cheap drug not like the expensive pure coke she was getting. there is something called a functioning addict . it means someone who is doing drugs but there are no obvious signs that the person is doing drugs. so whit could have been a functioning addict in the 80's then it got exposed when she used more or harder forms of the drug
