A cigarette you are stuck with 7357 chemicals and whatever else they toss in the cigarette. This is NOT control because there is no control of what is in a manufactured cigarette. At least with vaping the user controls the nicotine... If the person DIYs the E-liquids all aspects are controlled from nicotine%, flavor%, even VG PG ratio, even coils being used, and wicking.  With regulated the mods users control how much or how little power people need. Even RTA's RDA's and sub-ohm tanks all have different pros and cons from air flows, sizes, to wicking even they way people vape MTL RDL RMTL..... Vaping is so customizable to the persons tastes, needs and likes this makes it truly a user choice on portion control
