Yes—exercise is increasingly becoming a component of many treatment programs and has shown efficacy, in combination with cognitive-behavioral therapy, for promoting smoking cessation. Exercise may exert beneficial effects by addressing psychosocial and physiological needs that nicotine replacement alone does not; attenuating negative affect; reducing stress; and helping prevent weight gain following cessation. Research is currently under way to determine if and how exercise programs can play a similar role in the treatment of other forms of drug abuse.
