This debate is decades old... When I was a student it was always structured as Alcohol vs Weed.
The outcomes are always the same:
Yes - on a purely statistical level, and especially viewed through a societal lens, alcohol is a very harmful drug.
All drugs harm in different ways, Alcohol's harm doesn't manifest through the same mechanisms as smoking or weed or cocaine etc. But it does manifest and is objectively the cause of a large amount of harm (especially large because it is legal compared to other drugs)
Being 100% logically consistent, the debate tends to conclude that if you had a fresh society and analyzed all substances equally from scratch.. alcohol would be controlled to the same degree as other dangerous substances. That level would have to be consistent.
E.g. very little restriction on most dangerous substances, or bans on most etc. The level would change, but the consistency needs to be there.
However, the side of the debate in favor of bans always has to concede that in practice we live in a world grounded in history and context, and as such (as shown in America in the 20s) trying to remove something which is such a huge part of society, life, and such a normal thing for many, who will never have a problem with it, is not just impossible, it is dangerous and would cause even more problems.
