I've been vaping for about two months now, and they've been the 18 mg all along (I was smoking a pack and a half a day of Marlboro Lights for years and years and figured that was the ideal level). I haven't smoked a cigarette since, but always felt like I was just sucking the life out of the things to get a hit. Just tried a 24 mg that I got in a swap... WHOA! Full satisfaction. Just placed an order for six or seven (can't remember exactly) packs of cartos last night at 18mg, and just emailed Val asking her if it was possible to switch them to 24 mg if it's not too late. Either way, I think I'll be going with the 24 mg from now on. There goes my plan to eventually quit vaping
