It probably contains Butane, I have a few that also produce the green flame, it actually comes from a small ball of metal near the top of the flame output thing that heats up and releases something that turns the flame green. I don't use it for anything, I used to use it when I smoked cigarettes, and it didn't seem any different from any other lighter.
LiquidOC Reviewed by LiquidOC on . Green Flame Lighters My friend bought me one of those lighters that has a green flame. After taking a bong hit with it i noticed it tasted really wierd/painful. Are there any risks associated with using this type of lighter? Rating: 5
