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.
Minor (law)
In many countries, including Australia, India, Brazil, Croatia, and Colombia, a minor is defined as a person under the age of 18. In the United States, where the age of majority is set by the individual states, minor usually refers to someone under the age of 18 but can, in some states, be used in certain areas (such as casino gambling, handgun ownership and the consuming of alcohol) to define someone under the age of 21. In the criminal justice system in some places, "minor" is not entirely consistent, as a minor may be tried and punished for a crime either as a "juvenile" or, usually only for "extremely serious crimes" such as murder, as an "adult".
