You can definitely produce different highs with alcohol, getting drunk from vodka is different to wine is different to beer. In the end one is drunk, yes, but feeling is still quite distinct.
So pretty much the same as with pot, where you can have vastly different highs but in the end are just that: high
Not my experience at all. Give weed to 10 different people, and they'll experience 12 different reactions to it. With alcohol, it's more or less roughly the same for everyone.
Plus, there are people out there who don't experience euphoria from alcohol, it instead throws them into a depressive spiral.
