What's the vaping equivalent of smoking a cigarette in nicotine inhalation?

This is a common question and again, isn’t easily answered. One study using automated smoking machines suggested less nicotine is delivered by vaping than from smoking, but admitted this may not be accurate. The variety of vaping technology and individual inhalation techniques means there is no consensus on how much nicotine is absorbed during a single drag. More studies are needed to accurately measure this. Until then, the only advice is to, as with caffeine, try out different variations to find what suits your needs and stop vaping once you feel satisfied. Take consolation that no matter what, you’re consuming far less than the 4,000 chemicals typically found in tobacco smoke. If you have determined to give vaping a shot, suggest starting from Eleaf iStick series battery.
