By late 1920s, there were four main types of lighter in use – manual strikers, semi-automatic, automatic, and striker lighters. In the 1950s, the main fuel source for lighters became butane. This enabled creation of really light and disposable lighters that quickly spread all around the world.

The public population must be educated about the dangers of this gas and its bad outcomes and should be recommended to stay away from it.
