Okay, you guys and gals can pat yourself on the back all you want, but I'm still not buying it.
It appears as if you have to chain vap the strongest liquid out there to get your nicotine level up to 2 mg nicotine gum. That sounds a whole lot more like a smoking cessation program rather then a smoking replacement program. It's the real achilles heal of e-cigs.
It would also point to a high rate of failure. It's just not enough nicotine to be a good long term replacement for cigarettes.
Try not to take this the wrong way, though you already have, I'm not against e-cigs. I just don't think it's a good smoking replacement for the masses. The average Jane and Joe just doesn't have the time to suck on an e-cig for 8 hours a day to try and keep there nicotine levels up to acceptable levels. Most people actually have to work for a living.
If anyone actually took the time to read the link I posted above you can see that I'm not alone in this. Until the manufactures can make some liquid that has a much higher absorption rate e-cigs are doomed to a second rate niche product. Not-quite-ready-for-prime-time. It's very easy to cut back on nicotine if that's what you want to do, just cut your nicotine level or use it less often. Unfortunately, with the current state of the art in e-cigs, you can't push it any higher if need be.
I think the e-liquid manufactures need to get on the ball and give the rest of us what is needed.
