“Several studies in the 1970s found that motor vehicle crashes increased significantly among teens when the MLDA [Minimum Legal Drinking Age in Australia] was lowered.”
“Recent neuro-imaging studies show that the human brain is still developing through to the mid 20s. Episodes of heavy alcohol use that are common amongst young adults have detrimental implications for healthy brain development. Research shows that when the MLDA is increased to 21, people under age 21 drink less overall and continue to do so through their early twenties. Decreasing the MLDA below age 21 has also been shown to result in population increases in other alcohol-related harms including suicide and youth crime.”
