Some e-cigarettes look similar in appearance to traditional cigarettes or cigars. Others look like pens or flash drives or have completely different designs.

Most of these devices use a cartridge that, if used once, is called a nicotine pod or, if refillable, holds an e-liquid (e-juice or e-liquid). This essential oil is a liquid that typically contains nicotine, flavoring, propylene glycol, and vegetable glycerin.
E-cigarette strength is determined by the nicotine content in the e-liquid and is expressed in milligrams per milliliter or as a percentage. However, recent studies have shown that e-cigarette product label concerns do not always provide accurate information about nicotine content in e-liquid.
