Did you know of any?
We had an elder that regularly drank wine and other cocktails. He would come to night meetings, including elder meetings, shall we say, "feeling good".
We had an elder that was losing it and failing because of old age/dementia.
I knew a lot of elder's wives that were on meds in order to function but I wasn't aware of elders under the influence of drugs. Just so-called "holy spirit".
