I heard many times when I was a witness how much "learning the truth" helped people. Many have been said to have become much better people. Addictions were given up. Anger subsided. Hippies became cleaned up better dressed people (apparently). These were the kinds of things I was told over and over again when I was growing up in JW land. Somehow, it sounded like to me anyway, just knowing "the truth" was all that was needed to give up smoking and the like.
How much real help was any of this to people in your experience?
