Oculos Aperire wrote "[the Bethel application asked] 'Have you ever smoked Marijuana?' Well I had.. so I never got accepted or even considered."
I also was seduced by the evil weed (and similar evil pursuits), disclosed it on the application, and was accepted. While at Brooklyn, I met many who had similarly been cannabis-corrupted (although not certain whether they disclosed it or not).
Marijuana use (and worse) didn't seem to be a disqualifier.... at least not in the early 1980s and at least not in my case.
