Countered Nick Barton, chief executive of Action on Addiction: "I can only speak of what I know, and having met the Duchess several times I find her to be engaging, natural and genuinely interested in the subject. You can tell a lot about someone from the questions they ask and she asks really good questions, the questions of someone who wants to learn. She is also an intelligent woman."Added Barton of the Duchess' efforts: "She is doing an enormous amount to reduce the stigma of addiction and increase understanding of it."
