I'm gonna make my own top 10. Most of the OP's top 10 can be categorized into health benefits and personal presentation....
1: Plainly obvious health benefits from not smoking (cardiovascular, pulmonary, dental, anti-carcinogenic, etc)
2: Plainly obvious personal presentation benefits of not smoking (smelling like crap, tooth yellowing)
3: You can vape indoors at home, or in the car, which certainly matters when it's 10 degrees or 100 degrees outside. No need to crack a window.
4: Flavor selection. Anyone seen Marlboro Strawberry Cheesecake Cigarettes? I didn't think so .
5: As long as you don't go crazy with hardware, it's a money saving enterprise.
6: Big clouds are fun. 'Nuff said.
7: No calories! Instead of finishing that bag of Doritos that will only make you hate yourself, why not go for a vape?
8: As long as the nicotine level is appropriate for you, you can vape all day!
9. Cigarettes aren't cool anymore; that was soooooo 1990's. High technology and nerdy electronic equations are cool now. Have you seen Glee and High school Musical?
10: Here's the big kicker... Nicotine on its own is considered to be neuroprotective. Whaaaa? That's right, just like a glass of red wine a day provides antioxidants for heart health and cancer prevention, nicotine (preferably not from cigarettes) has been shown to slow the rate of neural apoptosis (translation: Brain and nerve cells essentially killing themselves), and therefore prevent the worsening of cognitive impairment, Alzheimer's Dementia, and generalized dementia.
So, not only is vaping (versus smoking) linked to undoing the damage of smoking, it can actually be beneficial in and of itself.
I like this list better than the OP's! lol. #10 especially. I drip 8mg's of nic and I'm staying right there. I need to work on the munchies and work on the hardware spending. I'm under control when it comes to mods, but I keep wanting a new dripper ever 3-4 weeks lol. The messed up part on that, I'll use the new dripper for a bit, find something wrong with it, and go back to my daily driver.
