I sent a pm to medhelp, maybe that will get the topic moved...
I'm going to go out on a whim and guess yes it indicates danger. Drinking alcohol leaches out many important vitamins. If you want I can google and pull up some helpful links. Combine the vitamins lost with alcohol consumption with poor nutrition, he is being malnourished. It certainly is not good for anyone's health.
I'm not sure this got posted where you wanted it, so I reported it as a mis cat. Hopefully medhelp can place this topic where you can get the most help.
I assume this belonged in the hep forum community, based on examining your profile?
