Smoking cessation has received little attention in substance abuse programs. The present study analyzed the effect that counselor and client education in nicotine addiction had on clients' treatment readiness for a smoking cessation program. Thirty-eight smoking clients and two counselors from a short-term residential alcohol treatment facility participated in this study. Counselors served in both the treatment and control conditions in this 2x2 mixed factorial design by first participating in the control condition (general substance abuse education) and then in the treatment condition (smoking education). Counselors proceeded to work (for 6 weeks) with clients who had participated in the control education in general substance abuse issues and with clients who participated in the treatment education series in smoking issues. Clients completed the Fagerstrom Test for Nicotine Dependence and Stages of Change Ladders pre- and posttest. Results indicated that counselor and client education was effective in significantly changing the clients' thoughts toward smoking cessation and their smoking behaviors. Implications for instituting a smoking education program involving counselors, as well as clients, are discussed.
