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.
Ages of consent in the United States
The age of consent, at the time applying only when the girl is the younger party, was 10 when California introduced its penal code in 1850. In 1889 the age of consent was raised to 14. In 1897 the age of consent became 16. The age of consent in California has been 18 since 1913. Some media sources reported that the age of consent in California in the 1970s was 14 or 16 but in fact it was and has been 18.
