I don't know right now, especially if you are referring to someone who's actively drinking. I am working on building trust with my RAH right now and it's not easy. My dad was a problem drinker and an alcoholic according to my mom. She finally left him when, after years of asking, he wouldn't quit drinking to save his family. A few years later he called me in college and told me I should have never been born, that they should have aborted me, etc. So, technically, I don't trust ANY active alcoholics based on my past experience.
