Some states allow parents to do this with their own child (rarely, if ever, with someone else`s child), but there is no evidence that this approach actually works.3 In fact, there is evidence to the contrary. When teens feel they have their parents` consent to drink, they do so more and more often when they are not with their parents. When parents have concrete and enforced rules on alcohol, young people drink less. References 3. Fell, James. Excerpt from «Chapter 2: Federalism: Solved, the Federal Government Should Restore the Freedom of Every State to Set Its Drinking Age.» in Ellis, Richard and Nelson, Michael (eds.) Debating Reform. CQPress Publishers, Fall 2009. A survey for the Center for Alcohol Policy found that 86 percent of Americans support the legal drinking age of 21.  Numerous national and national surveys from the 1970s (when states raised the legal drinking age) to the present day have shown overwhelming public support for MLDA 21.    In the late 1960s and 1970s: the age of alcohol consumption was lowered. In the late 1960s and 1970s, almost every state lowered the age of alcohol consumption to 18. This has led to a huge increase in alcohol-related car accidents, and drunk driving has been seen as a public health crisis.
In the mid-1970s, 60 percent of all road deaths were alcohol-related, according to the National Institute of Health (NIH). More than two-thirds of car accidents involving people aged 16 to 20 were alcohol-related. This is a major problem among public health officials, as late adolescence is one of the most important stages of cognitive development. The brain undergoes significant restructuring and specialization during this period, including the elimination of unnecessary neural connections and the refinement of connections between frontal-subcortical brain regions. Research shows that alcohol consumption, especially through excessive alcohol consumption, before the brain is fully mature, can permanently damage the brain and impede cognitive development. Yes. Injuries caused by adolescent alcohol use are not inevitable, and reducing adolescents` access to alcohol is a national priority. Since then, arguments against the age of alcohol consumption have persisted.
Some argue that the illegality of alcohol gives it a «taboo stimulant» and actually increases the alcohol quotas of minors. Others argue that if you can fight in war, you should be able to drink. As you can see in the table below, there has been a lot of volatility in the age of alcohol consumption in the states since prohibition was repealed in 1933. Shortly after the 21st Amendment was ratified in December, most states set their purchase age at 21, as that was the voting age at the time. Most of these limits remained constant until the early 1970s. From 1969 to 1976, about 30 states generally lowered their purchasing age to 18. This was mainly due to the fact that the voting age was lowered from 21 to 18 with the passage of the 26th Amendment in 1971. Many states began lowering their minimum age for alcohol consumption in response, most of which occurred in 1972 or 1973.    Twelve states have maintained their purchasing age at 21 since the repeal of prohibition and have never changed it. 76% of bars sold alcohol to obviously drunk customers , and about half of drivers arrested for driving under the influence of alcohol (DWI) or killed because drivers involved in alcohol drank in traffic accidents in licensed facilities   . Neighborhoods with a higher density of bars, nightclubs, and other liquor outlets are more likely to suffer from assaults and other violent crimes.
  18-year-olds generally enter a new phase of independence from their parents through university or staff and are more susceptible to excessive alcohol consumption, risky sexual activity and other irresponsible behaviour due to lack of maturity. In fact, young people in Europe have higher rates of intoxication than in the United States, and less than a quarter had lower or equivalent rates than in the United States. In addition, a higher percentage of young people in much of Europe report drinking alcohol more frequently than their American counterparts. 1-2 Most European teenagers have higher rates of alcohol-related problems due to their heavy alcohol consumption. Perhaps the best example of facts versus myths is what happened in New Zealand.
