Some great ideas, copied over here from an inappropriate marketing thread about Camel Crush cigarettes....
Due to my recent conversion to drip smoking only, I'm convinced e-cigarette makers need to look closely at this.
I think what we need instead of cartridges that contain "a pack's worth of smoking" are cartridges that contain about 2 or 3 drops of e-liquid in a capsule. In my admittedly limited experience with drip smoking, 2-3 drops equal about a cigarette's worth of smoking. So, with cartridges like this, you'd just pop in a new one, give a squeeze, push a button, or whatever to break the capsule, release the liquid into the atomizer, and then enjoy your cigarette's worth of nicotine puffing.
This would give the cartridges the self-limiting nature that some of people miss about regular cigarettes, and it'd take care of the problem of cartridge fibers getting stuck in the atomizer, producing nasty tastes, smells, and potential health concerns.
Yeah! Great idea. You get an e-cig with rechargable batteries and everything. But the refills you buy... They're sold like a pack of tic-tacs. You take one out, put it in your e-cig, push a button the side of the cig (It would crush or dissolve the capsule) and you get 1 cig worth of smoke. You could even buy them in more familiar cigarette nicotine strength. Like light cigarettes have what, .5mg of nicotine? You would buy a pack of .5mg capsules.
You put the e-cig back in your pocket when it stops making smoke. That way there's no leaking and it's easier to change flavors.
I want one of those.
