CBD & Cigarette Addiction In a double-blind, placebo-controlled study, 24 smokers were randomly chosen to receive either an inhaler of CBD or a placebo. Participants were asked to take a puff every time they had an urge to puff a cigarette. Over the week, those with placebo inhalers saw no change in their total number of cigarettes consumed, while those who were taking CBD saw a nearly 40 percent drop in their intake. Using the inhaler decreased the number of cigarettes without increasing their craving for nicotine, pointing towards a purpose for cannabidiol in the withdrawal process.
