According to a randomized, double-blind, placebo-controlled 2015 Preliminary Study* on 24 smokers who wished to quit smoking (in which 2/3 of the group received a CBD inhaler and the other 1/3 a placebo inhaler and were all told to use it when they felt the urge to smoke) CBD inhalation devices reduced the number of cigarettes smoked by 40% during the week of treatment.
