Total vaper for almost 4 years (will be 4 this month). I was a dual user for the first month, until I found the setup that worked for me.
Honestly, I don't think there is anything wrong with dual use. We always had a saying on ECF: Don't count the ones you have, count the ones you DON'T have. It is, after all, harm reduction.

you all whether you are a dual vaper or total vaper. What matters is that you are not taking in all the crap that you used to when you smoked. Even it if it is half, it is still a victory.
