Drinking is a huge problem among JWs. Many of them drank heavily. As well as CTD mention, I knew man who died from cirrhosis in my old KH. Sometimes he will get so drunk that he will open doors and yell through entire block, but his wife was extremely orthodox pioneer. My JW uncle drunk a lot as well, but hid it from his family that he crashed at my dad or grandma. Once my uncle was so drunk that he attacked my dad tearing his ear and broke his head, and my dad ended in emergency room to get stitches. When I was kid this uncle often would sleep on the stairs outside the house as my dad would refuse to open the doors for kids safety.
Also in the early 1990's elders got so drunk after program in KH that one of them waddled out and pied on the street right next to bus stop in public.
