Mood-Altering 'Euphoric Beverages' Are the Alcohol-Free Drinks We've Been Waiting For
There have always been lots of reasons to drink alcohol , and the events of 2020 have only added to that list. But one of the biggest reasons for people drink is to enhance a sense of social connection with others. For many people, that benefit alone is worth the negative side-effects associated with drinking, like hangovers or loss of control. But over time, it can also seem as if alcohol is pro
