<P> As one can see in the table below, there has been much volatility in the states' drinking ages since the repeal of Prohibition in 1933 . Shortly after the ratification of the 21st amendment in December, most states set their purchase ages at 21 since that was the Voting age at the time . Most of these limits remained constant until the early 1970s . From 1969 to 1976, some 30 states lowered their purchase ages, generally to 18 . This was primarily because the voting age was lowered from 21 to 18 in 1971 with the 26th amendment . A lot of states started to lower their minimum drinking age in response, most of this occurring in 1972 or 1973 . Twelve states kept their purchase ages at 21 since repeal of Prohibition and never changed them . </P> <P> 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 . </P> <Table> <Tr> <Th> State </Th> <Th> Pre-Prohibition (prior to 1919) </Th> <Th> Post-Prohibition (after 1933) </Th> <Th> 1970s / 26th Amendment (adopted in 1971) </Th> <Th> 1980s / Drinking Age Act of 1984 </Th> <Th> 21st century </Th> </Tr> <Tr> <Th> Alabama </Th> <Td> Pre 1881: None 1881: 21 (none with consent of parent) </Td> <Td> 21 </Td> <Td> 1970: Lowered to 19 </Td> <Td> 1986: Raised to 21 </Td> <Td> 21 (no one underage is allowed consumption Section 28 - 1) </Td> </Tr> <Tr> <Th> Alaska </Th> <Td>? </Td> <Td> 21 </Td> <Td> 1970: Lowered to 19 </Td> <Td> 1984: Raised to 21 with grandfather clause (if born before January 1, 1965) </Td> <Td> 21 </Td> </Tr> <Tr> <Th> Arizona </Th> <Td>? </Td> <Td> 21 </Td> <Td> 1972: Lowered to 19 </Td> <Td> 1985: Raised to 21 </Td> <Td> 21 </Td> </Tr> <Tr> <Th> Arkansas </Th> <Td> Pre 1925: None 1925: 21 </Td> <Td> 21 </Td> <Td> 21 </Td> <Td> 21 </Td> <Td> 21 </Td> </Tr> <Tr> <Th> California </Th> <Td> Pre 1891: Regulated by municipality / county (common age was 16) 1891: 18 (statewide) </Td> <Td> 1933: 21 </Td> <Td> 21 </Td> <Td> 21 </Td> <Td> 21 (except small amounts for religious ceremonies) </Td> </Tr> <Tr> <Th> Colorado </Th> <Td> None </Td> <Td> 1945: 18: for beer 21: for wine and liquor </Td> <Td> 18 </Td> <Td> Raised to 21 in 1987 </Td> <Td> 21 </Td> </Tr> <Tr> <Th> Connecticut </Th> <Td>? </Td> <Td> 21 </Td> <Td> 1972: Lowered to 18 </Td> <Td> 1982: Raised to 19 1983: Raised to 20 1985: Raised to 21 </Td> <Td> 21 (exemptions: (1) a person over age eighteen who is an employee or permit holder under section 30 - 90a and who possesses alcoholic liquor in the course of such person's employment or business, (2) a minor who possesses alcoholic liquor on the order of a practicing physician, or (3) a minor who possesses alcoholic liquor while accompanied by a parent, guardian or spouse of the minor, who has attained the age of twenty - one .
