It is a relatively unpopular emoji, and is most likely to be used by adults, particularly those in the 18-25 age range. It is most commonly used on Twitter, Instagram, and Facebook. This emoji is not necessarily considered rude, but it can be interpreted as such depending on the context in which it is used.
The history of this emoji dates back to the late 1990s, when it was first included in the Unicode Standard. Since then, it has been used in a variety of contexts, from representing smoking in general to being used as a symbol of rebellion or as a way to indicate someone is feeling stressed. In recent years, it has become increasingly associated with the vaping and e-cigarette industry, as well as being used as a way to represent smoking in a more general sense.
