The volume of nicotine may be higher, but note that the 'nicotine content' marked on cigarettes is generally the amount considered to be available/absorbed, whilst the content marked on e-liquids is the total present. Whether the amount absorbed is higher I'd be interested to know. I suspect it depends quite strongly on the mechanism (tiny vape pen vs mech setup, how long vapour is held before exhaling, etc).
