I believe this article on the Department of Intoxicating Substances is flawed.
The article references a sign at the Harry Potter Wizarding World which is located in Orlando, Florida, USA, but still argues that the legal drinking age is 18 years as is the legal drinking age in the UK, and not 21 years which is the legal drinking age in the state of Florida.
The article also states that this department is probably a sub-department of another department such as the department of magical law enforcement without any form of refrence to why this assumption is made.
I feel that this should be rectified as soon as possible, but I do not want to step on the authors toes so to speak, and will therefor leave it to the author to change this article.
