Abstract
An electrical smoking article is provided in which tobacco flavor medium is carried past a heater by a continuous web. The web, which preferably is substantially non-combustible, may bear continuous tobacco flavor medium or spaced-apart portions of tobacco flavor medium. A flavor cassette for such an electrical smoking article is also provided. The cassette resembles a conventional recording tape microcassette, having the web in place of magnetic tape. The cassette may also include the heater past which the tape is indexed to heat individual portions of tobacco flavor medium.
