Psychiatrist and addiction expert Judson Brewer was researching better treatment options for alcohol and cocaine addiction patients and found, through clinical studies, that meditation could significantly help break these behaviors or "habit loops" and prevent relapses. Brewer, who is now the director of research at the University of Massachusetts School of Medicine's Center for Mindfulness, founded a company called Claritas MindSciences, which uses neurofeedback techniques combined with mindfulness exercises for several conditions, from eating disorders to smoking addiction.
