Interestingly, this question has been asked many times in the 3+ years I've been on this forum. If you did a search you would see the average answer used to be about 3-4ml. Now it seems closer to 12ml.
That has a lot to do with the types of delivery devices people are using now......they drink ejuice like crazy.
I finally joined the 21st century and bought a nautilus a few weeks ago.......used it for exactly 1 day before i got rid of it. The amount of ejuice I went thru was about triple what I usually vaped. That, in terms of ejuice cost, combined with the actual coils themselves (not to mention how much more expensive a nautilus is for an over-the-counter delivery device) put my vaping budget WAY higher than I care to have it.
Not to mention, I really don't know IF I actually vaped 12ml instead of 3ml (my normal) or if the delivery device just burned off / consumed more ejuice during it's workings.
I just have no desire to put 3x as much flavorings, etc. into my lungs on a daily basis since I vape for harm reduction. I honestly feel that there was "more" harm reduction inherent in my earlier vaping days, so I have stuck with "older" hardware. After all, I did quit smoking using that stuff (and believe me, the pickins' were pretty slim back in 2012) and figure I really don't need to spend gobs of money as well as inhale 3x as much ejuice in order to "hold steady" (not smoking for 3+ years).
I guess I am not one who really *understands* the more, more, more concept.
I remember eating out at those places where people would anecdotally tell me how much food they got, so much so that they would have gobs of it to take home. My philosophy was always "why would I want MORE mediocre food instead of less truly fantastic food?
And those joints that sling 3x as much food as a person should eat at one sitting (unless they are pushing for diabetes, heart attack, obesity, etc.) aren't using the highest quality ingredients, or they couldn't afford to serve like that.
So, for me, in terms of harm reduction, whether it be eating, drinking alcohol, or vaping...........less will always be more.
All that said, when I was first quitting smoking, I allowed myself whatever was needed to get the job done, so the OPs question may be tied to where one is in their vaping journey.
After the first year, I just left my vape gear on counter, requiring me to "walk over" to use it. That was because I had and still have very clear personal goals related to all this "habit stuff". I did not want to be tied like a goat to a stake to cigs, but I certainly also don't want to be tied like a goat to a stake with my ecig either. I guess you could say I just want the freedom of not depending on an object quite that much, and that has little to do with whether it is good or bad for you.
I used to not be able to "wake up" w/out coffee. There have been a number of times when coffee first thing in a.m. was not possible (a thousands scenarios, everything from being a caregiver to a very ill person to guest somewhere or camping out in woods) and I literally felt like I would walk into a door or something. That bothered me. So I did start to restrict my use of coffee for a while, and to this day, I don't use it like i used to.
The idea that "I can't function normally" without a substance ....... well,
I just don't want any monkeys on my back.
