Electronic smoking article

Abstract

An electronic smoking article includes a first section containing a liquid supply reservoir including liquid material, a heater operable to heat the liquid material to a temperature sufficient to vaporize the liquid material and form an aerosol, and a wick in communication with the liquid material and operable to deliver the liquid material to the heater, and a second section containing a power supply. The first section is connected to the second section at a breakaway connection. The breakaway connection includes a weakened region.
