The recent Amethyst Initiative argues that a minimum legal drinking age (MLDA) of 21 has created a culture of heavy alcohol use on college campuses by making drinking clandestine and extreme. This group and others argue that lowering the MLDA will reduce the problem of "binge drinking" on college campuses. However, such a policy change would remove one of the most researched and supported policies in the nation's alcohol control arsenal. There is little evidence that other interventions or policies are capable of working on the same broad level as MLDA 21, and there could also be a deleterious ripple effect in related legislation because MLDA 21 works in conjunction with other drinking laws. In addition, historic and international experiences with a lowered MLDA indicate there are serious social and public health consequences. Instead of removing efficacious interventions, we must remain committed to implementing and enforcing evidence-based practices and legislation.
最近的紫水晶倡议认为，最低法定饮酒年龄（MLDA）提高到 21 岁，使得饮酒变得秘密和极端，从而在大学校园里造成了酗酒文化。该组织和其他组织认为，降低 MLDA 将减少大学校园里的“狂饮”问题。然而，这样的政策改变将取消国家酒精控制武器库中最具研究和支持的政策之一。几乎没有证据表明其他干预措施或政策能够在与 MLDA21 相同的广泛层面上发挥作用，而且相关立法也可能产生有害的连锁反应，因为 MLDA21 与其他饮酒法律一起发挥作用。此外，降低 MLDA 的历史和国际经验表明，存在严重的社会和公共卫生后果。我们不应该取消有效的干预措施，而必须继续致力于实施和执行基于证据的实践和立法。
