CBD is known to help with addiction.
According to one study, twenty-four smokers were given a placebo or an inhaler with CBD. The twenty-four people were split into two groups of twelve. One group received CBD; one group received a placebo inhaler. The study was carried out over seven days.
The study subjects were encouraged to use the inhaler each time they wanted a cigarette. Those receiving placebo did not change the number of cigarettes they smoked that week. In contrast, those treated with the CBD significantly reduced the number of cigarettes smoked in a day by 40%.
