Most people who try a caffeine vaporizer report that it gives them a fast, non-jittery burst of energy. It works faster than ingesting caffeine in the form of coffee, tea, or edible supplements, because the dose is absorbed into your bloodstream almost instantly. Because you feel the effects quicker than coffee, it's easier to avoid taking too much caffeine by mistake. Researchers are still working on confirming what energy vape users know, but the evidence is starting to build up. One study published in Brain Science reported that participants who tried a commercial caffeine vape did better at mental tasks than those who only used flavored vapes. We're looking forward to seeing these results repeated and expanded!
