Int J Clin Exp Hypn. 2004 Jan;52(1):73-81. Thirty smokers enrolled in an HMO were referred by their primary physician for treatment. Twenty-one patients returned after an initial consultation and received hypnosis for smoking cessation. At the end of treatment, 81% of those patients reported that they had stopped smoking, and 48% reported abstinence at 12 months post treatment. Most patients (95%) were satisfied with the treatment they received.
