Coming of age
In the United States, teenagers are allowed to drive at 16 in all states except New Jersey, which requires drivers to be 17 and older, and sometimes receive the responsibility of owning their own car. Teenagers may drive at age 15 in Idaho and Montana. At 16, teenagers are also old enough to donate blood and work in most establishments. At 18 one is legally considered an adult and can vote and join the military. The legal age for purchasing and consuming alcohol and recreational marijuana, the latter of which is only legal in the District of Columbia, Colorado, Oregon, Washington, California, Hawaii, Massachusetts, Nevada, and Alaska, is 21. The legal age for purchasing and consuming tobacco products is 18 in most states; 19 in Alabama, Alaska and Utah; and 21 in California, New Jersey, Oregon, Hawaii and Maine. Multiple localities have also raised the minimum purchase age independent of state laws.
Sexuality in the United States
Sexual relations are mostly legal in the United States if there is no direct or unmediated exchange of money, if it is consensual, teleiophilic (between adults) and nonconsanguineous i.e. between people who are not related familially or by kinship. There are however exceptions, with for instance adult incestual relations being legal in states such as New Jersey and Rhode Island as of 2017. Prostitition laws in the USA are by far the strictest in the developed world, but the state of Nevada licenses several of its counties to operate brothels and permits prostitutes/sex workers to sell sex, and janes and johns to purchase sex. The age of consent laws in the USA are by far the strictest in the developed world, with 18 being the age of consent unlike in Europe and Canada where it varies from 14-16. There may occasionally be some exceptions to age of consent laws in age gap laws, with some states permitting an ephebophilic relationship if the two persons are close in age.
