I can say that for some of the booze hounds I've worked with.
There are plenty of congressman, governors, Military commanders, professional athletes, doctors and lawyers who are alcoholics, how many heroin addicts are in prominent positions? heroin addicts may be do ok as Rock Stars or something but what else can they do?
there have been plenty of high functioning drug addicts in positions of responsibility
That's somewhat analogous to saying that "there have been plenty of high function autistic people".
However, I think we can all agree that it's a better hand to not be autistic.
