A study carried out by a British research team from the University of London and specialized in psychopharmacology, has set the objective of evaluating the effect of CBD (cannabidiol) on smoking cessation. The clinical study was carried out against placebo by including 30 dependent smokers under strict abstinence of nicotine, that is to say, not treated for smoking cessation by nicotine substitutes (gums, patches) or consumers of nicotine liquids for electronic cigarette. The volunteers consumed 800 mg of CBD orally before bedtime. On waking up, the following criteria were measured in particular: the desire to smoke, the attraction for tobacco in general (visual stimuli), the effectiveness of withdrawal. After a night of abstinence from cigarettes, it is observed that CBD induces a decrease in blood pressure. It also appears that CBD significantly reduces the psychological attraction for tobacco and positive stimuli induced by smoking. On the other hand, it has no effect on the reduction of the desire to smoke and the withdrawal.
