What behavior is typically illegal for juveniles but legal for adults, pertaining to age restrictions?

Substance use is often subject to legal age restrictions, making it illegal for juveniles to consume alcohol or use other regulated drugs, while adults have the legal right to do so once they reach the designated age. In many places, the legal drinking age is 21, and similar age restrictions apply to the purchase and use of recreational drugs. This creates a legal framework where actions permissible for adults are prohibited for minors, highlighting the societal concerns regarding health and safety for younger individuals.

Other behaviors such as gambling typically have age restrictions as well, but they may vary widely by jurisdiction, and some places may allow certain forms of gambling for teens. Public speaking does not have age restrictions and is a right afforded to all individuals regardless of age. Driving requires a permit or license, which is regulated but is not uniformly illegal for juveniles as many can legally obtain learner's permits or licenses at a younger age depending on local laws. Therefore, the clear distinction in legal statuses concerning substance use makes it the most notable behavior that is legal for adults but illegal for juveniles.
