A Dream e-cigarette is like a real cigarette, but without the smoke. And the smell. And the carcinogens, carbon dioxide, tar, tobacco cravings, lighters, matches, ash-trays, ash and butts.
Instead of burning nicotine-infused tobacco and inhaling the smoke, you heat nicotine-infused water, and inhale the vapor. (You can choose nicotine-free too.)
The flavor and strength of your e-cig come from the "juice" in the cartridge. You can choose the combination of flavors and strengths you like best, just as you can with real cigarettes.
But unlike a cigarette, an e-cig cartridge can last you all day. Each cartridge is worth an entire package of cigarettes.
