Well, I have no idea about cinnamon, or clove hen not mixed with tobacco. Aside from that, a menthol or clove cigarette/cigar versus a vape with those flavors? You're getting the same flavors as you would from a tobacco, without thousands of extra chemicals, including 40-70 carcinogens, depending on whose number you go by. If you weren't a menthol or clove user, don't inhale those flavors, if there is something that concerns you. Most of your nicotine intake from vaping seems to be induced through the oral and nasal soft tissue: the inhalation satisfies the mind, not the body.
