I looked into vaping back in 2010 only as a means of saving money. I was a 5 pack a day Marlboro red smoker and figured if I could just cut down to a 3rd of the value it would be worth it. That was may 2010 and a few months of figuring what I liked and what worked for me I started smoking less and less.
Eventually I noticed I had not opened the pack of regular smokes I had purchased and looked at the receipt date, it was 8/10/2010.
At that point I was 6 months cigarette free.
I did slowly work my way down nicotine wise with my high being 36mg freebase nicotine.
Today I’m not nicotine free, sometimes I alternate between 2mg and 0mg depending on what I feel like mixing that day.
