No one said non smokers should start vaping nicotine, you sure like read more into the words on the screen than what is actually there, aka, make stuff up.
Anyone with enough gumption to select a setup & e liquid, charge a battery, fill a tank & press a fire button has enough intelligence to be aware of & perform routine maintenance. Those that chose to remain willfully ignorant about simple things need written directions and safety nets to walk to their mail box unassisted.
I had no idea you knew most vapers, wow, that's a whole bunch people, your Christmas card list must be humongous.
Since you're "out of this discussion" allow me to say;
Well,, bye.
Or,
Bye, Felicia
Whichever you like best.
