paragraph_text: New Jersey's drinking age was lowered to 18 in 1973 as part of a broader legal change which reduced New Jersey's age of majority from 21 to 18. Much of the impetus for lowering the drinking age to 18 was to grant returning Vietnam veterans the right to purchase alcohol. Possibly because of concerns about 18 - year - old high school students being able to legally purchase liquor, and then illegally consume it school, the state raised the drinking age to 19 in 1980. Citing statistics that indicated an increase in car deaths among drivers under 21, the drinking age was raised back to 21 in 1983. At the same time, the penalties for underage drinking were increased to include a mandatory driver's license suspension. In 1985, the state made it illegal for an adult to give alcohol to a person under 21, with exception for religious services and parents serving alcohol to their own children at home or in a private area.

paragraph_text: In law, a minor is a person under a certain age, usually the age of majority, which legally demarcates childhood from adulthood. The age of majority depends upon jurisdiction and application, but it is generally 18. Minor may also be used in contexts that are unconnected to the overall age of majority. For example, the drinking age in the United States is usually 21, and younger people are sometimes called minors in the context of alcohol law, even if they are at least 18. The term underage often refers to those under the age of majority, but it may also refer to persons under a certain age limit, such as the drinking age, smoking age, age of consent, marriageable age, driving age, voting age, etc. Such age limits are often different from the age of majority.

paragraph_text: From 1976 to 1983, several states voluntarily raised their purchase ages to 19 (or, less commonly, 20 or 21), in part to combat drunk driving fatalities. In 1984, Congress passed the National Minimum Drinking Age Act, which required states to raise their ages for purchase and public possession to 21 by October 1986 or lose 10% of their federal highway funds. By mid-1988, all 50 states and the District of Columbia had raised their purchase ages to 21 (but not Puerto Rico, Guam, or the Virgin Islands, see Additional Notes below). South Dakota and Wyoming were the final two states to comply with the age 21 mandate. The current drinking age of 21 remains a point of contention among many Americans, because of it being higher than the age of majority (18 in most states) and higher than the drinking ages of most other countries. The National Minimum Drinking Age Act is also seen as a congressional sidestep of the tenth amendment. Although debates have not been highly publicized, a few states have proposed legislation to lower their drinking age, while Guam has raised its drinking age to 21 in July 2010.

paragraph_text: In response to the National Minimum Drinking Age Act in 1984, which reduced by up to 10% the federal highway funding of any state which did not have a minimum purchasing age of 21, the New York Legislature raised the drinking age from 19 to 21, effective December 1, 1985. (The drinking age had been 18 for many years before the first raise on December 4th, 1982, to 19.) Persons under 21 are prohibited from purchasing alcohol or possessing alcohol with the intent to consume, unless the alcohol was given to that person by their parent or legal guardian. There is no law prohibiting where people under 21 may possess or consume alcohol that was given to them by their parents. Persons under 21 are prohibited from having a blood alcohol level of 0.02% or higher while driving.

paragraph_text: New Jersey and all other U.S. states comport with the requirement of the National Minimum Drinking Age Act of 1984, which sought to set a national standard of 21 as the minimum age for purchasing and publicly possessing alcoholic beverages. To make states comply, Congress tied a state's failure to enact a drinking age at 21 to a punitive decrease in a state's apportionment of federal highway funding. Federal law requires colleges and universities that accept federal financial aid institute policies to sanction students who violate underage drinking and other alcohol laws, and to track the number of liquor laws violations. The Chronicle of Higher Education has reported that many colleges fail to comply with these laws, and federal enforcement is minimal.
