Action on Addiction, in association with the University, trains addiction advisers at a higher level.
“We’re all excited about HRH The Duchess of Cambridge’s visit to our Centre for Addiction Studies (CATS) next month!” Action on Addiction tweeted on November 27.
The royal visited Send Women’s Prison in September, where she met inmates who had been victims of various addictions.
After her visit to the women’s prison, Kensington Palace shared Duchess Kate’s thoughts on its official Twitter account.
“Addictions lie at the heart of so many social issues .. substance misuse can play such a destructive role in vulnerable people’s lives,” she said. “Failure to intervene early in life to tackle mental health problems and other challenges can have profound consequences.”
“I am grateful to the women I met for sharing their difficult personal stories with me,” the Duchess added.
