Despite my advancing years and a lot of bad habits like smoking, I've managed to stay in pretty good shape and can still press about 100 pounds more than my body weight. Blood pressure has never been an issue with me, but much to my chagrin, it had creeped up to 145/80 at my last physical. The only thing that had really changed was that I quit smoking and started vaping.
Nicotine can increase blood pressure, and I was certainly vaping a lot more than I was smoking so I looked at the numbers. At a pack and a half a day of Marlboro Reds a day, there were approximately 36 mg/day of nicotine going into my system. Some studies suggest that 90% of the nicotine in an analog gets destroyed by heat; other studies (New Zealand) suggest that most of the nicotine from vaping gets absorbed by the body since it is not being destroyed by heat.
If that is the case, then a chain vaper really needs to look at how many milligrams a day he/she is ingesting. If you vape 2 mL a day of 24 mg juice, you are ingesting 48 mg of nicotine a day. 2 mL a day is nothing for a chain vaper.
So I adjusted the concentration of my juices to rebalance my daily intake of nicotine; my blood pressure dropped to 126/78 within a matter of weeks.
