The amount of time it takes to feel the effect of CBD varies depending on the individual, the reason for using the CBD, and the form of CBD oil they are using. CBD oil can be used orally, topically, or inhaled as vapor.
Vaping is the quickest option, as it is disbursed through the bloodstream. With orally dropping the oil you can expect anywhere from 20 to 40 minutes before the CBD will take effect. Topically, on the other hand, is used for spot-specific skin issues and will take somewhere around an hour to take effect.
