That's the only reason I started vaping as well. The hobby side though is starting to grab a hold of me.
But yeah, if you want to quit smoking, I suggest to stop thinking about it & just do it.
back up, charger, everything you need except ejuice.
Not really a lot of money, $16.50 each. You'll get your money's worth out of it & you can always upgrade whenever you like, if you like.
Go to your local smoke shop, vape shop, or convenience store. If you see a rig for $20 or less, get it. If money's no object, grab something you like. Anything, just get started. Buy some eJuice. Around here, the locals usually have stuff ranging from $5.99 to $9.99 for a 10ml bottle. I'd go ahead and get 18 mg or 12 mg strength. Puffing that is as satisfying as puffing a cigarette. If you're used to taking 20 drags on a cigarette, about 20 drags on that liquid should fix you up. If you're used to taking 10 drags, 10 drags on that juice should be about the same. (I know it's not scientifically, or technically correct, but in my experience, it's pretty close).
I was a light smoker & vaped about 1.5 ml/day when I started. That was my equivalent to 7 cigarettes a day. So if you smoke a pack a day at 18mg nicotine, I'd expect you to use about 3 times as much, a little less than 5 ml/day but I don't trust that conversion, I think it's not likely that you'll be vaping that much a day right off the bat.
So anyway, a 10ml bottle should last you about 2 days. You already cut your cost of smoking in half (if you were a PAD smoker). So I'd buy two or three bottles. Should last you anywhere from four to six days.
Then I'd go to $4.99 for a 15 ml bottle great customer service & quick to get your order out. Most likely same day, even on a weekend. I'd buy two or three bottles of whatever flavor you like at 18 mg, then two or three bottles of the same stuff 0 mg. Then you can adjust how much nicotine you're vaping. 1 part 0 mg to two parts 18 mg gives you 12 mg strength. two parts 0 and one part 18 mg gives you 6 mg. You'll probably start vaping more & more, and being able to cut the nicotine strength yourself is going to come in real helpful until you figure it out. Then you can just order the strength that you settle on.
