Re: Why, you utter barstewards
The article refers to alcohol/drug dependency not necessarily being a barrier. To my mind dependency still ought to be a barrier, although use may not be. For example "use", such as occasionally puffing on a jazz cigarette could be viewed as no worse than popping down to the NAAFI bar for some beers. But "dependency" is a much bigger deal, likely to impact on a person's behaviour in a way that renders them unsuitable for service.
