I would also add to this list that you didnt have the right PG\VG mix.1. You were probably not introduced to vaping in the best way, and therefore Ill-advised.
2. You more than likely did not have the correct amount of nicotine for your smoking habits.
3. You did not have a handfull of flavors that you personally enjoy.
As a once heavy smoker and cold turkey quitter I just had to add my two cents on this. I smoked three packs of unfiltered Camels per day while I was enjoying a one year vacation courtesy of Lyndon Johnson. (RVN for those of you who are not of my vintage). Quit almost 50 years ago after smoking for six years.
Smoking is smoking, nicotine is nicotine and very bad for you. The warning on the package is not there just to please the health fanatics. Inhaling any kind smoke is bad as in inhaling coal dust. Folks, you just want to inhale pure air.
E-cigarettes are just a way of circumventing the current laws on cigarettes. And why do you think that the flavored ones are so popular among the youth. So they will buy them and become addictive.
Go see a good doctor, get the patches, chew the gum. Do anything, have some will power. Don't blame it on others, you have to be strong for yourself.
As for switching from cigarettes to the "E" kind to stop. Just another way of killing yourself.
Sorry for the rant. But they are just bad things.
Now I am going to go out and have a shot of Woodford Reserve.
50 years ago the medical fraternity stated that smoking was good for you.
Agh, good old days, I remember the Marlboro Man, a dead fit cowboy type. I used to smoke Marlboro, then went on to English fags like No.6, smoked them for years. I'm on Rothmans now although I do splash out on some non tipped like Senior Service every now and then. But at £12 ($14) ish for a pack of 20 it's not cheap.
Thank god I've got a good pension or I might have to cut down or even give up. Sometimes I pop over to Belgium on Eurostar to buy fags in bulk, much cheaper there.
