Age of Adulthood

Original Question

Is it a logical fallacy to say that an 18 year old is not an adult until their 21 because they can't drink, smoke, or get a gun in most states? I've heard many adults say this and I wanted to know your opinion. Is there a difference in a "legal adult" and someone who has become an adult? Does the age of majority count in this context?

I see no logical fallacy, just general ambiguity (i.e., the poorly defined term "adult"). Adulthood is generally a socially constructed concept with a legal and biological counterpart. The solution to such an argument is simple: ask what they mean by adult. It sounds as if they are defining an adult as one who can drink, get a gun, etc. That is even more arbitrary then the rights that one gets at 18 (legal adulthood) and certainly more arbitrary than when one is fully grown or developed (biological).
