2. How do Ruyan smoking substitutes/cigarette alternatives work?

The Ruyan E-cigarette and E-pipe are sophisticated electronic devices. They use modern microelectronic technology, rechargeable lithium ion batteries and unique, safe replaceable cartridges. When using these products, drawing on them will produce a water-based, nicotine-infused vapor that smokers find satisfying and bystanders find safe and non-offensive. Additionally, the products provide the physiological and psychological effects that many smokers require for a satisfying experience.

The Ruyan Vegas E-cigar uses the same technology, except in a disposable package, with a pre-loaded, non-replaceable cartridge.
