Electronic Cigarette

As the slogan for a smokeless world has been raised, a new practice called “vaping” has come to the forefront recently, but vaporizers/e-cigarettes were invented back in the 60s. The earliest e-cigarette can be traced to Herbert A. Gilbert, who in 1963 patented “a smokeless non-tobacco cigarette” that involved “replacing burning tobacco and paper with heated, moist, flavored air”. This device produced flavored steam without nicotine. The patent was granted in 1965. This concept never took off because smoking was still fashionable back then.
