Good question, and having been just babtized in the late 60's I remember too well the Elders who did smoke, the ones that were df'd in the early 70's when the "new light" burnt them outa the borg. Some mannaged to quit, but others were destined to become "closet" smokers, later just faded away only to return sometime after the 1975 upset. Anyone remember the resurgence of those coming back to the truth in the early 80's? They've pretty much have all faded away now too.
Don't even get me started on alcoholism and the Society! Well ok, here goes (getting on my soap box). In my 48 years IN, I honestly cannot think of one Elder who didn't drink, and I'm sure half of all the ones I've known are full blown alcoholics, so are their wives, as were a lot of the CO's that made the rounds. It's a known fact that alcoholism adversely affects family life, ruins your health and it runs in families, children of alcoholics are more likely to become alcoholics, and or marry one and so it goes. The fact is alcoholism is so prevalent in the borg and to me it sure explains a lot of the black and white thinking that goes on. Imagine if they started df-ing those who drank in the congergations, that alone would render the 'borg empty!
